Don’t worry, there is nothing that needs to be done!
We automatically detect this and send the messages in a way that they will not be affected. If we detect a DMARC policy of Reject or Quarantine, we will automatically use our email address ([email protected]) as the sender (with your name) and set the reply-to to be your email address.
This will avoid the DMARC policy, and your emails will continue to be sent without issue.
