# Email Templates

> Keep one master design and reuse it across sequence steps and campaigns without editing the original

# Email Templates

You can reuse any email in a campaign or sequence, even if it is not marked as a
template. Marking an email as a template keeps it easy to find in the template
picker. Starting from a template always creates an independent copy, so you can
change the copy and images for each step while the original stays untouched.

## Mark An Email As A Template

* On the **Emails** page, open the row menu and choose **Mark as template**.
  Templates move into their own **Templates** section at the top of the page.
* In the standalone email editor, use **Save as template** in the header.
* In the campaign editor, open **Campaign settings** beside **Send Test** and
  choose **Save as template**.
* Campaigns using a marked email show a **Template** badge beside their name
  in the campaign list.
* Over the API, CLI, or MCP, set `isTemplate` on
  [Create Template](/api-reference/templates/create) or
  [Update Template](/api-reference/templates/update), or pass
  `--template` to `sequenzy templates create` and `sequenzy templates update`.

Any email works as a master: a campaign you already sent, an email built in the
editor, HTML you imported, or a designed template from the gallery.

## Use A Template In A Sequence

When you add a **Send Email** step, the **Start from** row lists your templates.
Pick one, describe what the step should say, and choose:

* **Generate in this design** - AI rewrites only the text inside the template
  for your description. Layout, imagery, links, colors, and merge tags stay
  exactly as designed. If the rewrite cannot be validated, the step still gets
  a clean copy of the template and you edit the text yourself.
* **Use a copy** - duplicate the template as is and edit it in the editor.

Either way the step gets its own email. Editing it never changes the template
or any other step.

When AI starts from a gallery design, illustrative testimonials, offers, and
other unsupported sample content are removed before writing. Your verified
brand and catalog content is retained. Saved company designs and **Use a copy**
keep their original content.

Choosing a marked template through **Change email** on an existing step also
creates an independent copy. Plain copies keep the template's saved translations.
AI rewrites use your company's translation settings to translate the new content;
they do not reuse translations of the old copy.

## Use A Template In A Campaign

Open **Use one of your emails** in the campaign template picker. Templates are
copied into the new campaign the same way.

## Sharing Versus Copying

Steps can also **link** an existing email instead of copying it. A linked email
is the same record everywhere it is used, so an edit in one step shows up in
every other step and campaign that uses it. The sequence canvas marks these
steps with a **Shared** chip, and the step panel offers **Make an independent
copy** when you would rather detach.

| Rewrite text with AI while preserving a selected design                                                  | **Generate in this design** | Not available; creating with `prompt` generates new content without preserving a source layout |

These standalone/sequence copy and rewrite flows are an intentional dashboard-only
exception in this release. They are scoped to interactive authoring, where
you can inspect the source design, translations, and any unchanged fallback copy
before saving the sequence step. Public template creation accepts supplied content
or generates new content; it does not expose the source-design and fallback
guarantees of the dashboard workflow.

For an integration, use the public create operation with your finished `blocks`
or `html`, or use `prompt` for new AI-generated content. Reading an existing email
and submitting its content as a new template does not automatically copy its
localized variants; those must be supplied through the localization operations.

Campaign creation already supports copying an existing company template through
[`POST /api/v1/campaigns`](/api-reference/campaigns/create) or MCP
`create_campaign` with `templateId`. That existing workflow is separate from this
exception; `templateId` cannot be combined with `prompt` for an AI rewrite.
