Adding/Changing/Deleting a Sender Name


Use different sender names to separate different types of emails and let subscribers filter your messages. For example:

  • promos;

  • messages from managers;

  • triggered emails, etc.

You can add or change a sender in a few ways:


Before configuration, you must add email authentication.

  • Contact field data

To add a dynamic sender address, follow the next steps in the email editor.
