Campaigns - Sequenzy

Sequenzy campaigns dashboard with callouts showing how to create and open a campaign

Campaigns are one-time email broadcasts sent to a segment of your subscribers. Use them for announcements, newsletters, promotions, and any communication that goes to multiple people at once. Workspaces with the SMS add-on can also send SMS campaigns: the Campaigns screen gains an Email / SMS switch, and text campaigns follow the same message, recipients, schedule, and review steps. See SMS campaigns for the SMS-specific rules. When you create an email from a prompt in the dashboard, your first applied AI result saves automatically. Wait for the save confirmation before refreshing. Later edits still use Save; if the automatic save fails, your result stays in the editor and you can click Save to retry.

Safety Review

Scheduling a campaign can put it in waiting_approval instead of scheduled. This is an anti-abuse hold, not an error: nothing is sent while a campaign is in this state, and the campaign is not lost. This most often happens on new accounts. The checks run against your account and your sending domain, so a brand-new workspace or a recently registered domain is the usual reason a first send is held. Once your account and domain have a track record, later sends normally go straight to scheduled. A campaign is held when any of these apply:

New or unverifiable domain. Your sending domain or your company website domain was registered in the last 7 days, has no public registration record, or the website did not respond when we checked it.
Content that matches known abuse patterns. Business-opportunity, guaranteed income, or high-pressure “act now” language in the subject, preheader, or body.
Automated content review. Campaigns to 10 or more recipients, or campaigns whose content hits our review watchlist, are checked automatically before the first send.
Contacts held for review. If your audience includes contacts our team is reviewing, the campaign is held whatever its size.

Campaigns to fewer than 10 recipients skip the automated content review, so tests and one-off messages send without waiting. If an account dispatches 5 or more of these small campaigns within 24 hours, the review applies again to the rest - splitting one large send into many tiny ones does not avoid it. The domain and abuse-pattern checks above always run. New senders do not get the small-send exemption. While your account is under 7 days old, has not completed a campaign yet, or has delivered fewer than 100 emails, every campaign is screened automatically before it sends, whatever its size. Sequence and transactional emails get the same screen. It usually takes a few seconds and can take up to about two minutes, so the first schedule call or the first sequence email of a new account may wait that long. A screen that passes sends normally. One that flags the content holds the campaign in waiting_approval as described below. Established accounts that our team has marked as trusted skip these checks, except the hold for contacts under review, which applies to every account.

What happens next

Held campaigns are reviewed by the Sequenzy team. When a review finishes:

Approved - the campaign returns to scheduled and sends at its original time. If that time has already passed while it waited, it moves straight to sending.
Rejected - the campaign moves to rejected and the reason is available in rejectionComment on GET /api/v1/campaigns/{campaignId}, sequenzy campaigns get <id>, and the get_campaign MCP tool.

The hold is evaluated per schedule call, not stored permanently on the campaign. Fixing the underlying cause (verifying a domain that now has history, rewriting flagged copy) and scheduling again is enough - you do not need a per-campaign exemption.

If you are building an unattended integration, treat waiting_approval as a normal outcome of scheduling. Check status in the schedule response, and if it is waiting_approval, log it and poll the campaign instead of retrying the schedule call. Retrying will not clear the hold.

If your account sends automated campaigns and you keep hitting review, contact support and ask to have the workspace marked as trusted. There is no API parameter or dashboard setting that bypasses the review.

Creating a Campaign

Sequenzy campaign template picker with callouts showing template styles and a starting point

1. Choose Recipients

From Subscribers, apply filters or select contacts, then choose Create campaign. Analytics activity groups offer the same action. Choose a template, use an existing email, start blank or write an AI prompt. The complete matching group across every page is saved directly in the campaign when you create the draft. This does not create a list, change list membership or enroll contacts in sequences. New matching contacts do not join the draft automatically; edit its selected contacts or use a saved segment if you want a changing audience. Email eligibility is checked before sending. Saved lists and segments keep their existing Create campaign and Create sequence actions. Unsaved filtered groups offer campaign creation only. Draft campaign rows show an Audience set chip when an audience has been configured. It is not a final recipient count; review the audience before sending. Use Create Campaign for a Group, sequenzy campaigns from-audience, or MCP create_campaign_for_audience to create a blank draft with the same frozen contact selection. Update its content using the existing campaign tools before reviewing and sending.

Sequenzy campaign recipient step with callouts showing include rules, exclusions, and audience preview

Define who receives the campaign: All Subscribers

Recipients: All active subscribers
Filters: None

Filtered Segment

Recipients: Filtered
Filters:
  - Status is "active"
  - Tags contains "customer"
  - Tags not_contains "churned"

2. Select Email Template

Choose or create the email content:

Use an existing template from your library
Create new content in the editor
Duplicate and modify a previous campaign

You can also make individual blocks conditional. In the block settings, use Conditional Display to show that block only when a recipient value matches a rule such as equals, contains, exists, or numeric comparisons. Conditions are not limited to profile values: you can also target segment membership, custom events (for example “performed purchase in the last 30 days”), tags, lists, subscription status, engagement (opened or clicked recently), Stripe and store purchases, signup date, email provider, and SMS status - the same filters you use to build segments. These rules are checked against live subscriber data when each email is sent. For an else branch, use the Conditional (if/else) block, or duplicate the block and invert the rule on the copy. Attribute and variable conditions use the same merge-tag variable names you already use in emails, but without the {{ }} braces.

3. Choose Sender

Select who the email appears to come from:

From: "Sequenzy Team" <hello@sequenzy.com>

4. Schedule or Send

Send Now: Queue immediately
Schedule: Pick a specific date and time
Spread Over Time: Distribute sends linearly over 1–72 hours

You now choose these in two layers:

Start time: Send now or schedule a future start
Delivery strategy: All at once, Spread Over Time, or Send Time Optimization

5. Review and Send

Sequenzy campaign review step with callouts showing campaign details, final audience, and email preview

Use the final review step to verify the subject, sender and reply-to identities, resolved audience, delivery plan, and rendered email. Send a test first when you have changed personalization or conditional content, then confirm the campaign. When you click Send Now or Schedule Campaign, Sequenzy shows Ready to send? with a last check of your email: every link and image is opened to find broken pages, dead domains and missing images, and the content check lists anything left to fix, such as placeholder text. Nothing there blocks sending; if something needs attention the button reads Send anyway, and Edit email takes you back to the content.

Checking your email

The badge in the editor toolbar opens the email check. It groups findings by links, images, content, subject line, preview text, accessibility, email clients and sender, and Show next to a finding selects the block to fix. Links and images are checked live as you edit: each one is opened from our servers and reported as working, broken (page not found, domain doesn’t exist, certificate problem, redirect loop), unreachable, or couldn’t verify when a site refuses automated checks. Without a request, the check also flags links missing https://, mistyped addresses, localhost and staging URLs, placeholder domains such as example.com, link shorteners, and link text that shows a different domain than the link goes to. Links built from merge tags that change per recipient are only checked for valid syntax; {{company.url}} links use your company website. To run the same check outside the editor, use the Check Campaign endpoint, sequenzy campaigns check, or the check_email MCP tool. Sequence steps and templates have matching checks.

Delivery Options

These options refine how a campaign goes out. Choose them in the Schedule step.

Recurring Campaigns

Scheduled campaigns can repeat automatically. When scheduling, set Repeat to “Every week” or “Every month” and the campaign becomes a recurring template:

At each run time, Sequenzy duplicates the template into a normal one-shot campaign and sends it
The audience is re-evaluated at every run, so new subscribers who match the list or segment are included and removed ones are skipped
Each run gets its own campaign (named after the template with the run date) with its own stats
The email content is snapshotted per run - you can edit the template between runs, and the next run picks up your changes without altering past runs
Cancel the recurring campaign to stop the series; runs already sent are unaffected

Recurring campaigns pair well with dynamic product lists: a repeat block with Recommended products and Rotate between sends turned on sends each subscriber a fresh selection every month without repeating what they already saw.

If the platform is briefly unavailable at a run time, the run starts as soon as it recovers. Runs missed by more than the full interval are skipped, not sent in a burst.

Spread Over Time

Enable Spread Over Time to distribute your campaign sends gradually over a configurable window, protecting your sender reputation during warmup. How it works:

Choose when the campaign should start sending
Select “Spread over time” as the delivery strategy
Use the slider to choose a delivery window (1-72 hours)
The first batch sends at the chosen start time
Remaining batches are spaced evenly across the window

When to use:

Warming up a new sending domain
Sending your first large campaign (1,000+ recipients)
You’ve sent fewer than 10,000 emails total (Sequenzy will recommend this automatically)

Example:

Campaign start: Tomorrow at 9:00 AM
Spread window: 12 hours
Subscribers: 1,200
Chunks: 5

Chunk 1: Sent at 9:00 AM
Chunk 2: Sent at 12:00 PM
Chunk 3: Sent at 3:00 PM
Chunk 4: Sent at 6:00 PM
Chunk 5: Sent at 9:00 PM

Spread Over Time and Send Time Optimization are mutually exclusive. You can only enable one per campaign.

Recipient Limit

Turn on Recipient limit on the schedule step to send to only part of the audience. Enter the maximum number of recipients and Sequenzy keeps the first that many matching subscribers, ordered by subscriber ID, after every audience rule, exclusion and suppression is applied. When to use:

Ramping up a new sending domain a few hundred contacts per day
Soft-launching an offer or price change to a small group before the full send
Working through a large import in daily batches
Capping send-quota spend on a campaign whose segment keeps growing

The review step shows the capped count (“First 100 of 950 recipients”) and the send resolves the cap when it starts, so a segment that grows in the meantime still sends to at most the number you set. If you pause and resume a capped campaign, recipients already reached count against the limit. Duplicated campaigns and recurring runs keep the limit. For A/B tests, allow at least one recipient per variant plus one for the winner. Invalid enabled limits block sending; turn off the limit explicitly to send to the whole audience. To send the next batch, duplicate the campaign and add an audience filter such as Email sent was not sent ever so contacts who already received it are excluded, then set the next day’s limit. The same field is available as maxRecipients in the API, the CLI (--max-recipients) and MCP.

Attachments

A campaign can carry up to 10 files, 5MB in total, that every recipient receives, such as a weekly PDF report. CC and BCC copies and test emails get the same files. Add them with attachments when you create or update a campaign through the API, with sequenzy campaigns create --attach ./report.pdf in the CLI, or with the create_campaign and update_campaign MCP tools. The dashboard shows attachments in the review and sent views; use the API, CLI or MCP to change them. Sends, test emails, duplicates and recurring runs include them. Sequenzy loads every file when sending starts. If one is missing or too large, nothing is sent and the campaign returns to draft so you can fix it; a resumed send stays paused and shows the reason. Keep URL files available until the campaign finishes sending: a file removed mid-send stops the remaining recipients. Large attachments make every email heavier, so link to big files instead.

Pauses and Sending Locks

A manual campaign pause stores the pause on that campaign. You can resume it from the campaign page, and Sequenzy uses the saved spread setting unless you choose a new one on resume. Company sending pauses and account bans act as parent sending locks. When the lock engages, every campaign that is mid-send is paused automatically with the label Paused with company sending (or Paused with the account for a ban), so no further chunks are attempted while the lock is active. Scheduled campaigns keep their schedule and show Sending paused until the lock clears. When the lock is removed, those campaigns resume automatically on the normal resume path: remaining recipients continue at the same pacing as before the pause, using the saved spread setting. Scheduled campaigns that came due during the pause start; future scheduled campaigns wait for their scheduled start. You cannot resume one of these campaigns on its own while the company lock is still active; the campaign page, API, CLI and MCP explain which lock applies. An admin restoring sending can leave those campaigns paused instead. They then stay paused until you resume them from the campaign page, API, CLI or MCP. Campaigns you manually paused before the company lock engaged remain paused when company sending is restored.

Automatic Pauses for Deliverability

Sequenzy watches each campaign’s own bounce, temporary bounce and complaint rates while it sends. Once a campaign has sent at least 50 emails, it is stopped when 20% or more of them hard bounce, 50% or more soft bounce, or 1% or more draw a complaint. For an established sender, only that campaign is paused, with the label Paused automatically for deliverability and the rate that tripped. Your other campaigns, sequences and transactional email keep sending. The campaign does not restart when company sending is restored. Clean the recipient list, then resume it from the campaign page, API, CLI or MCP. Its rate is measured over the whole send, so it pauses again if the rate stays over the limit. A sender counts as established with at least 20,000 sent emails, a workspace older than 30 days, a paid plan, and no recent pause for phishing, content review, complaints or an admin hold. For other senders, company sending is paused instead. It is also paused when campaigns are paused this way 3 times within 24 hours, including the same campaign pausing again after a resume. While company sending is paused, resume it before resuming one of these campaigns. Company-wide bounce and complaint limits also still pause company sending on their own.

Send Time Optimization

Enable Send Time Optimization to deliver emails at each subscriber’s optimal time based on their engagement patterns. How it works:

Toggle “Send Time Optimization” on the schedule step
Sequenzy analyzes each subscriber’s historical open times (last 90 days)
Emails are delivered within a 12-hour window at each subscriber’s optimal hour
Subscribers without enough data receive emails at the scheduled time

Requirements:

Subscribers need at least 5 email opens in the last 90 days
The UI shows how many subscribers have computed optimal times

Example:

Campaign scheduled: 9:00 AM
12-hour window: 9:00 AM - 9:00 PM

Subscriber A: Usually opens at 2:00 PM → Sent at 2:00 PM
Subscriber B: Usually opens at 6:00 PM → Sent at 6:00 PM
Subscriber C: Not enough data → Sent at 9:00 AM (scheduled time)

After sending, view the delivery distribution chart to see how STO spread your campaign across hours.

Recipient’s Local Time

Deliver a scheduled campaign at the same wall-clock time in every recipient’s own timezone - “send when it’s 8pm for the customer”. How it works:

Store a timezone on your contacts (see Subscribers) - via the API timezone field, a CSV import, the MCP tools, or the contact page
On the schedule step, pick a date and time and choose “Recipient’s local time” as the delivery strategy
Each contact receives the campaign when their local clock reaches the scheduled time. Timezones ahead of yours are delivered earlier - processing starts when the scheduled time first occurs on Earth (UTC+14)
Contacts without a stored timezone receive the campaign at the scheduled time in your timezone, and timezones whose local time already passed when processing starts receive it immediately

Notes:

The option is available once at least one recipient has a known timezone; the schedule step shows how many contacts will get local-time delivery
Not combinable with repeats, Spread Over Time, or Send Time Optimization
Also available from the API (sendInRecipientTimezone + scheduledTimezone), the CLI (campaigns schedule --in-recipient-timezone --scheduled-timezone), and the MCP schedule_campaign tool

Example:

Campaign scheduled: 8:00 PM in New York

Subscriber A (America/New_York):   Sent at 8:00 PM New York time
Subscriber B (Asia/Tokyo):         Sent at 8:00 PM Tokyo time (13 hours earlier)
Subscriber C (no timezone stored): Sent at 8:00 PM New York time

Filtering Options

Status Filters

Filter	Description
`is subscribed`	Only active subscribers
`is_not subscribed`	Exclude active (rare use)

Tag Filters

Filter	Description
`contains [tag]`	Has the specified tag
`not_contains [tag]`	Does not have the tag

Example: Target customers, exclude churned:

Tags contains "customer"
Tags not_contains "churned"
Tags not_contains "unsubscribed"

Email Filters

Filter	Description
`contains [text]`	Email contains text
`not_contains [text]`	Email does not contain text
`is [address]`	Email is exactly this address
`is_not [address]`	Email is anything but this address

is and is_not match the full address and ignore case, so they are the right choice for explicit allowlists (QA contacts) and exclusions. Use contains when you want a domain or substring. Example: Target company emails:

Email contains "@company.com"

Example: Only a fixed list of test contacts:

Email is "qa1@company.com" OR Email is "qa2@company.com"

Date Filters

Filter	Description
`less_than [value]`	Added within/after a value
`more_than [value]`	Added before/older than it

You can use rolling values like 7 days ago, natural language like last week, or fixed dates like 2026-03-01 and Mar 1 2026. Rolling values update automatically as time passes. Fixed dates stay fixed. Examples:

Added less_than 30 days ago
Added more_than 2026-03-01

More targeting examples:

Status is "active"
Added less_than 7 days ago
Tags contains "customer"

Tags contains "trial"
Added more_than Mar 1 2026

Attribute trial_ends_at lte 3 days from now
Email contains "@company.com"

Name Filters

Filter	Description
`firstName contains [text]`	First name contains
`lastName contains [text]`	Last name contains

Filter Combinations

Filters are combined with AND logic:

Tags contains "customer"
  AND
Tags contains "pro-plan"
  AND
Added more_than 7 days ago

This targets: Pro plan customers who signed up more than a week ago.

Variations Canvas

The email editor’s Canvas tab puts alternative versions of a campaign’s email side by side, so you can compare them before choosing one. Variations don’t change what the campaign sends until you use one.

Just say what you want. The Canvas chat reads each message to see what you’re asking for. With an email or some of its sections selected, an instruction like “make the hero dark” or “I don’t like this” changes that email in place, with Undo. Ask for options (“give me 3 headline options”) to compare a few versions of the selected sections, or for variations (“2 more variations”) to get new emails. Say how many you want, or leave it to the assistant.
Ask for variations. Describe a direction and the new versions appear as each one is ready, and keep generating if you reload or leave the page. Each takes its own direction and its own structure in your brand’s look, so they differ from each other. Ask for “more like this” to stay close to a version you liked, or for “something completely different” to get bold versions with their own layout, colors and fonts. The AI Assistant in the Edit tab offers Create 2 vastly different variations too. You can also ask the AI Assistant in the Edit tab for “three variations” and it opens the canvas instead of editing the email. Requests that rely on attached images or your GitHub repository stay normal edits. Up to 8 versions can generate at once for one email. On an empty email, each version is a complete first draft.
Change one part. Click a section inside a selected variation (Shift-click to add more) and say what should change; ask for options to get a few to compare instead: hover to preview one in place, then Apply. Undo steps back through your changes, newest first.
Move around. The canvas zooms and pans like a whiteboard: scroll to pan, pinch or hold Cmd/Ctrl and scroll to zoom, and drag empty space to move around. Arrows show which variation each one came from, labeled with the request that made it. Drag a variation by its title to place it anywhere; Tidy up puts everything back. Show everything (Shift+1) fits all variations on screen.
Use one. Use in campaign puts the variation’s content in the email and saves it, including its own colors and fonts when it has them. If the email’s current content isn’t already a variation, it’s kept as a new one first (“Before V2”), so you can always go back. Variations that follow your email’s look keep the one they had.
Discard. Discarded variations can be restored with Undo. Their branches move up a level while they’re gone.

The canvas is available for a campaign’s main email in its default language. It isn’t shown while you edit an A/B test variant, a translation, or an HTML email. You can do all of this through the API, with sequenzy campaigns variations in the CLI, and with the variation tools in MCP. Through those, using a variation works on draft campaigns only; in the editor it saves like any other change. Every email campaign can be shared through a public “view in browser” link - useful for showing a campaign to stakeholders, clients, or anyone outside your audience. Unlike the {{viewInBrowserUrl}} merge tag, which serves one recipient’s personalized copy, the share link renders an anonymized version: a sample contact instead of subscriber data, an inert unsubscribe link, and no open or click tracking. Click Share in the campaign editor to open the hosted page in a new tab - the link is minted automatically the first time, and drafts can be shared too, so you can circulate a campaign for review before it is scheduled or sent. Links can also be created via the API, with sequenzy campaigns share, or through the share_campaign MCP tool. The link is a high-entropy URL that only exists once it is created, and it is revocable via the API, sequenzy campaigns unshare, or unshare_campaign - after revoking, the old URL returns 404 immediately and sharing again produces a different URL. Transactional emails, sequence emails, and standalone templates can be shared the same way through their underlying email: use the Share button in the email editor, the templates API, sequenzy templates share, or the share_template MCP tool. Campaign links stay campaign-level so a shared A/B campaign always shows the winning variant.

Sending Process

When a campaign is sent:

1. Campaign marked as "sending"
         │
         ▼
2. Fetch all matching subscribers
   (apply filters)
         │
         ▼
3. Split into chunks of up to 500 recipients
         │
         ▼
4. Queue each chunk for processing
         │
         ▼
5. Each chunk:
   - Render email with personalization
   - Send via email provider
   - Record in analytics
         │
         ▼
6. All chunks complete
         │
         ▼
7. Campaign marked as "sent"

Personalization

Available Variables

Use these in your email content:

Variable	Description
`{{FIRST_NAME}}`	Subscriber’s first name
`{{LAST_NAME}}`	Subscriber’s last name
`{{NAME}}`	Full name
`{{EMAIL}}`	Email address
`{{customAttribute}}`	Any custom attribute
`{{subscriber.ATTRIBUTE}}`	Custom attribute, explicit form
`{{subscriber.firstName}}`	Same as `{{FIRST_NAME}}`
`{{html.subscriber.ATTRIBUTE}}`	Custom attribute rendered as raw HTML

The subscriber. prefix also accepts the contact’s core fields - {{subscriber.firstName}}, {{subscriber.lastName}}, {{subscriber.email}}, and {{subscriber.name}} - so either form works for those. A custom attribute of the same name still wins. The prefix is scoped to the contact, so it does not reach company or URL variables: use {{COMPANY_NAME}}, not {{subscriber.companyName}}.

Example

<p>Hi {{FIRST_NAME|there}},</p>

<p>As a {{plan}} customer, we wanted to share...</p>

<p>Your account: {{EMAIL}}</p>

The |there syntax provides a fallback if the name is missing, and {{ FIRST_NAME | default: "there" }} does the same thing.

A fallback hides a misspelled tag: if nothing provides the name, every recipient gets the fallback, including the ones whose real value is stored - and the email looks perfectly personalized. Rendering a preview reports these under unresolvedMergeTags with reason unknown, so check that list rather than reading the greeting.

Raw HTML Attribute Values

Merge tag values are always HTML-escaped, so an attribute holding markup like <p>...</p> renders as visible code. When a custom attribute stores trusted, prebuilt HTML - for example a unique per-recipient body your system generated - add the html. prefix to render it as markup:

{{html.subscriber.body_html}}

This lets one campaign deliver fully unique HTML per recipient while keeping campaign-level analytics: store each recipient’s body in a custom attribute, then use a single merge tag as the campaign content. It works in raw HTML campaign bodies, text blocks, and HTML blocks alike, and {{subscriber.subject}} in the subject line pairs with it for per-recipient subjects. Keep these rules in mind:

Only render HTML you generate or trust. Never route end-user input through a raw HTML tag; a regular {{subscriber.attribute}} stays escaped.
Injected HTML is sanitized: scripts, inline event handlers, and dangerous URLs are stripped.
The prefix only applies in HTML text position. Inside attributes such as href or src, the value is validated and escaped like an ordinary tag.
Store final HTML. Merge tags still present in the injected HTML are substituted before sending, so resolve your own placeholder syntax first.

The same prefix works everywhere merge tags render - sequences, templates, and transactional emails, where it also applies to API-passed variables like {{html.prerenderedHtml}}.

Tracking

Open Tracking

When enabled, Sequenzy tracks email opens via a tracking pixel.

<!-- Automatically inserted -->

You can enable/disable tracking per company in Settings → Tracking.

Analytics

When a Campaign Was Sent

Reopening a finished campaign shows the date and time it went out next to the Sent badge. A campaign without recorded pacing reads Sent <date>; a paced one reads Finished <date>, because for native sends that timestamp is when the last recipient was handed off rather than when sending began. Hover or focus the info button beside it for the recorded send strategy - no pacing recorded, spread evenly over a set number of hours, or at each recipient’s optimal open time - plus the scheduled time when one was set. Imported campaigns may not include pacing metadata from their source provider. The scheduled time is not presented as the actual start, because safety review or queue delays can postpone delivery. You do not have to open a campaign to check. Each row in the campaign list shows a relative age, and hovering its Sent badge gives the same record - the exact date, plus the recorded pacing when there is any. The same record is available outside the dashboard. sentAt, spreadOverHours, sendTimeOptimization, and sendTimeWindowHours all come back from List Campaigns, Get Campaign, the sequenzy campaigns list and sequenzy campaigns get commands, and the list_campaigns / get_campaign MCP tools. Change draft pacing with Update Campaign or apply it when scheduling. STO is campaign-only; sequences use a sending window instead. After sending, view campaign performance:

Metric	Description
Sent	Total emails sent
Delivered	Successfully delivered
Bounced	Failed to deliver
Opens	Unique opens
Clicks	Unique clicks
Unsubscribes	Opted out from this email
Open Rate	Opens / Delivered
Click Rate	Clicks / Delivered

Revenue Attribution

If you have goals configured, sent campaigns show revenue attribution metrics:

Metric	Description
Conversions	Goal conversions attributed to this campaign
Revenue	Total tracked value from attributed conversions

Attribution uses your workspace’s attribution window (24 hours unless you change it; campaign goals default to 7 days). See Goals for the window settings and supported billing integrations.

Tracking Over Time

View how engagement changes:

Day 1: 45% opens, 12% clicks
Day 2: 52% opens, 15% clicks
Day 7: 58% opens, 17% clicks

Most engagement happens in the first 48 hours.

Resending to Non-Openers

After a campaign finishes sending, you can resend it to everyone in the same audience who didn’t open it. This is a simple way to recover opens - a second touch, often with a fresh subject line, reaches the people who missed the first send. On a sent campaign, use the Send to non-openers button. Before creating anything, it shows an estimate of how many subscribers haven’t opened the campaign yet, so you know the size of the resend up front. Confirming creates a new draft named <campaign> (Non-openers) that:

Reuses the original campaign’s audience (all subscribers, lists, a saved segment, or a filtered audience), and
Adds a “didn’t open this campaign” rule so only people who haven’t opened it yet are targeted.

The draft is not sent automatically. Review it, tweak the subject line, then schedule or send it like any other campaign. Manual exclusions from the original send are preserved; manually added recipients are dropped so they don’t bypass the rule. Every audience format keeps opener exclusions that manual additions cannot override. Resending a resend also preserves exclusions from earlier campaigns. Your audience is evaluated live, so new members can qualify even if they never received the original. If an older resend draft lacks excludedCampaignOpenerIds, recreate it from the original campaign and review the new draft before scheduling.

Resending to non-openers becomes available 6 hours after a campaign finishes sending. This gives opens time to register, so the estimate and the resend audience are accurate. It is not offered for imported campaigns, which have no opens in Sequenzy to resend against.

This is also available outside the dashboard:

API: POST /api/v1/campaigns/{campaignId}/resend-to-non-openers (see the API reference)
CLI: sequenzy campaigns resend-to-non-openers <id>
MCP: the resend_campaign_to_non_openers tool

Imported Campaigns

When you move to Sequenzy, you can bring your old campaigns with you as historical records by creating them with status: "sent" and the original sentAt (see Create Campaign). Sequenzy records campaigns created this way as imported history and labels them Imported in the campaign list and on the campaign page. Only the email content and the send date come across. Sequenzy never delivered these campaigns, so it has no recipients, delivery records, opens, clicks or bounces for them - the campaign page says so in place of the usual analytics rather than showing zeros. Resending to non-openers is unavailable for the same reason. Everything else works normally: you can view and share the email, duplicate it into a new draft, rename it, and label it alongside the campaigns you send from Sequenzy.

Organizing Campaigns and Sequences

Sequenzy label settings with callouts showing reusable content labels

Labels group related campaigns and sequences into reusable collections. Open Settings → Tags & Labels to review existing collections, then assign labels from a campaign or sequence settings panel so related work stays easy to find.

Create a Label

Sequenzy label dialog with callouts showing label name and creation

Give the collection a short, recognizable name. Labels organize content only; they do not change recipients, enrollment, or sending behavior.

Best Practices

1. Test Before Sending

Send a test email to yourself
Check personalization renders correctly
Verify links work

2. Segment Thoughtfully

Don’t send everything to everyone:

✓ Feature update → Only to customers using that feature
✓ Upgrade offer → Only to free/starter tiers
✓ Renewal reminder → Only to annual subscribers

✗ Everything → All subscribers

3. Time Your Sends

B2B: Tuesday-Thursday, 10am-2pm
B2C: Evenings and weekends
Consider time zones: Schedule for recipient’s local time

4. Monitor Deliverability

Watch your metrics:

⚠ Bounce rate > 5%  → Clean your list
⚠ Complaint rate > 0.1%  → Review targeting
⚠ Open rate < 10%  → Improve subject lines

5. Respect Unsubscribes

Process unsubscribes immediately
Don’t re-add unsubscribed contacts
Provide easy unsubscribe links

Pick an A/B winner by revenue, a goal or an event

Opens and clicks are not always what you want more of. In Test settings under Pick winner by, you can also judge variants by what recipients did afterwards:

Most goal conversions: the variant whose recipients convert on a goal most often, per delivered email.
Most goal value: the variant that brings in the most goal value per delivered email. Choose Revenue to pick the variant that made the most money from purchases and orders.
Most recipients who fire an event: the variant whose recipients most often fire an event you choose, such as trial.converted, after receiving it.

A conversion counts for a variant when it is attributed to that email: the recipient opened or clicked it within the goal’s attribution window. For campaigns, built-in revenue and goals of that campaign also credit a recipient who received the email in that window without opening it. You can use built-in revenue, a company-wide goal, or a goal of this campaign. Give the test enough time for people to buy or convert; a short test window only sees fast conversions. If no variant has converted when the test ends, the winner falls back to click rate. Sequence A/B steps offer the same choices; there, contacts keep being split until one variant leads. When you duplicate a campaign or sequence, its test keeps built-in revenue, company-wide goals and events. A goal of the original campaign or sequence is not copied, so the copy’s test picks its winner by click rate until you choose another goal. Through the API, CLI and MCP, set winnerCriteria to goal_conversion_rate, goal_value or event_rate with winnerGoalId (a goal ID or default-revenue) or winnerEventName, for example sequenzy ab-tests update ab_123 --winner-criteria goal_value --winner-goal default-revenue. Get A/B Test Stats reports each variant’s conversions and value under outcome.

Control a running campaign A/B test

Your campaign review shows the fields that differ, winning metric, percentage of the full audience, assigned and sent recipients, total duration and deadline. Use Change time to set total minutes from the original start (15–1,440), Change sample size to set how much of the audience (5–50%) gets the test variants, or Finish test early to choose which variant the remaining audience receives. In Finish test early you can also pick Pick by [metric] now: the variant leading on the test’s winning metric so far wins, without waiting for the rest of the test time. Through the API, CLI and MCP, send endTestNow: true (sequenzy ab-tests update ab_123 --end-now). Already committed sends keep their variant. Pausing the campaign pauses delivery; changing settings does not resume it. You can retry a pending audience change or discard a failed one. The same workflow is available through Update A/B Test and Select A/B Test Winner, CLI ab-tests get, ab-tests update --test-percentage 30 --duration-minutes 120, and ab-tests select-winner, and MCP get_ab_test, update_ab_test, and select_ab_test_winner. Use --cancel-sample-update or cancelSampleUpdate: true to discard a failed request; repeat the same target or selected winner to retry.

Is the difference real?

Under the variant results, the campaign review tells you whether the leading variant’s advantage on the winning metric is statistically significant at 95% confidence, not yet significant, or still too early to judge (fewer than 30 recipients per variant, or too few opens or clicks). With more than two variants, the leader has to beat every other variant. Sequence A/B steps show the same note when metrics are visible on the canvas. The check is informational: automatic winner selection still picks the highest rate when the test period ends, so a leader that is not yet significant may be noise. Once a winner is chosen, the note keeps describing the test itself: it compares only the emails sent before the winner was picked, not the winner’s later sends to the rest of your audience. Get A/B Test Stats returns the same result as significance, sequenzy ab-tests stats prints it, and the MCP get_ab_test_stats tool includes it. When reducing a campaign sample, only queue jobs whose sends have never started and that have no committed recipients can be withdrawn. Active jobs and pending transport retries finish first, so the minimum can rise before the change applies. Retrying preserves the request; discarding a failed change keeps work already performed, including withdrawn sample jobs. Recipients without committed sends remain eligible for the eventual winner.
