Setting Up Your Sender Signature
Before customizing your email templates, set up a verified sender signature so emails are delivered reliably and appear from your domain.Click Set Sender Signature
In the Email Designer editor, click the Set Sender Signature button in the top-right header.
Enter your sender details
In the modal that appears, fill in the following fields:
- Sender ‘From’ Email: The email address customers will see as the sender (e.g.,
support@yourdomain.com). You’ll receive a confirmation email if this address hasn’t been verified before. - ‘From’ Name: The display name associated with the “From” email (e.g., “Your Brand Support”).
- Sender ‘Reply To’ Email (optional): The email used if a customer replies to a claim email. If not set, replies go to a masked Order Protection address via Postmark.

Configure DNS records
After adding your signature, you’ll receive an email from Postmark with the DNS records needed to verify your domain. Two records are required:
- DKIM — A TXT record that authenticates your emails.
- Return-Path — A CNAME record that ensures proper bounce handling.
