 Configure multiple servers to use both transactional and broadcast streams

You can configure multiple custom SMTP servers and assign one to each of your Postmark server types accordingly.

 Postmark’s Broadcast Stream will include their Unsubscribe link by default

If you do configure your workspace to send bulk emails through Postmark’s Broadcast Stream, an Unsubscribe link is required. Postmark inserts their own link into your messages by default, however you can opt-out of this by contacting Postmark Support. You can request removal of their link by informing them that you’re using’s built-in Unsubscribe link and management, and they’ll be happy to assist from there.
