Advanced Sender Routing

Advanced sender routing lets Sequenzy separate the address your recipient sees from the verified domain Sequenzy uses for routing and dedicated IP assignment. Example:
  • Visible From: hey@pawpulse.ai
  • Routed via: hey.pawpulse.ai
This is useful when you want a cleaner root-domain sender in the inbox while still isolating traffic on a verified subdomain.

​
Availability

This is available directly in sender profile settings. Sender profiles can keep a visible From address on one verified domain and route mail through another verified sending domain in the same workspace.

​
Requirements

  • The visible From domain must be verified in your workspace
  • The routing domain must also be verified in your workspace
  • Dedicated IP assignment follows the routing domain, not the visible From domain

​
What Changes

  • Recipients still see your visible From address
  • Sequenzy chooses the SES configuration set and dedicated IP from the routing domain
  • Campaigns, sequences, transactional emails, test sends, and forwarded replies all use the same routing decision

​
What Does Not Change

Advanced sender routing selects which verified domain Sequenzy uses for its managed delivery infrastructure. It does not configure a customer-managed outbound SMTP relay. External SMTP providers such as Hostinger cannot be selected as the delivery transport because Sequenzy owns outbound delivery. You can keep an external mailbox or alias as the visible From address after its domain is verified, and use it as Reply-To for manual replies.

​
In The UI

For most workspaces, sender setup still looks the same. Sender settings show an extra routing-domain control, and campaign review shows a small via your-subdomain.com hint when the visible sender and routing domain differ.

​
Several Display Names On One Address

One mailbox can carry more than one sender identity. hello@mail.example.com can send as Example for most of your mail and as Brennon at Example for a single sequence, without renaming the shared identity that every other campaign and sequence uses. Send fromEmail together with fromName and Sequenzy picks the identity of that name on that address, creating it the first time you use it. Matching ignores case, so a name you have already used is reused rather than duplicated. To rename an identity everywhere it is used instead, use update_sender_profile or sender settings. Reply-To works differently: an address carries one Reply-To display name for the whole workspace. If you send a replyToName that does not match the saved profile for that address, the saved name is kept and the response warnings array tells you so. Sequence email steps are the exception, because a step stores its own Reply-To header and applies the name you sent to that step only.

​
Best Practices

  • Keep both the visible From domain and routing domain under the same brand
  • Use a subdomain for routing when you want stronger reputation isolation
  • Move transactional and marketing traffic onto separate routing domains when possible
  • Warm up any new routing domain or dedicated IP gradually
