Workflow Builder: Pick an Email Sender Domain for Each Workflow!

What's new?

Workflow Settings now has a Sender domain dropdown under Sender details. Pick any verified dedicated domain on the sub-account and every email action in that workflow sends from it, the same way domain selection already works in Email Campaigns. If the sub-account has no dedicated domains configured, the dropdown doesn't appear.

How it works

The Sender domain dropdown shows all verified dedicated domains on the sub-account, plus All domains.

1. All domains: Enter the sender name and email prefix, such as 'marketing'. Emails continue to send across configured domains using weighted distribution configured in the sub account

1. Specific domain: Select a domain and enter the email prefix. For example, marketing with example.com sends as .

If you enter a full sender email on a different domain. In that case, the sender email overrides the selected domain and a Sender domain mismatch warning appears because mismatched domains may affect deliverability. Sender details set inside an individual email action take final preference over the workflow-level settings.

How to use it

• Add and verify your domain under Email Services, Dedicated Domains.
• Open the workflow, go to Settings, and pick the domain under Sender domain.
• Set a From name and From email, then save. Every email action in the workflow inherits it.

Why we built it

Until now every workflow in a sub-account went out on the same domain. You could change the From address on a workflow, but that only changes the name people see, not the domain the email is actually sent on, so a promo blast and a booking confirmation always rose and fell together. One bad campaign and risks that other email confirmations landing in spam as well.

Now you pick the domain workflow by workflow. Reminders and receipts sit on one domain, promos and cold outreach on another, and a campaign that lands badly costs you that domain alone. You can also try a new domain on a single workflow and watch how it does before moving anything else across.

Simple example

A sub-account sends appointment reminders and payment receipts on mail.acmeclinic.com, and runs its monthly promo nurture on news.acmeclinic.com. The promo volume builds reputation on its own domain, so a bad month there leaves the reminders untouched.

Additional Notes

• Only verified domains from Email Services show up in the dropdown.
• Sender details on an email action override what the workflow settings have, including the domain.
• Email headers configured in your dedicated email settings take priority over the ones in workflow settings.
