When sending a Mailchimp campaign, with your email address as one of the recipients, your campaign may appear in your junk email folder. In Gmail, you may even receive a warning that the email message may have been sent from someone purporting to be you (i.e. spoofing).
Below I discuss how to avoid this warning in Gmail.
Why the spoof Gmail warning appears
It is quite scary to receive the warning in Gmail however don’t be concerned if you know that you sent an email campaign from Mailchimp to yourself and this warning message appears.
From the perspective of Gmail it looks suspicious that you are sending yourself an email form a non-Gmail server.
How to resolve the Gmail spoofing warning
Once you’ve authenticated your domain, Gmail is able to identify that you use Mailchimp to send your email campaigns. The spoof warnings will stop showing and your campaigns will also stop going straight to the junk folder.
