GMail DMARC Update June 2016
Some time in June of 2016, GMail is updating their DMARC policy and it may affect your deliverability. For many ConvertKit senders, the change will have little or no impact on their regular sending. For others, it will require a little effort to avoid serious interruption. Either way, it’s worth understanding exactly what changes are being made and how it could affect you.
What is DMARC? It stands for Domain-based Messaging Authorization Reporting and Conformance Policy. It means that emails coming from an @gmail.com account can only be sent from their original servers.
Since you're using our ConvertKit servers to send your emails (and this is true for any other ESP too), your emails sent from an @gmail.com address - using an @gmail.com in the from address - will likely be bounced (read: your subscribers won't get your emails). Yahoo has had this same policy in effect for some time to cut down on SPAM but GMail is just now putting it into place so it's time to pay attention, GMail users.
What do I do about it?
You’ll want to create an email account using your domain name (ie: firstname.lastname@example.org) and use this for your ConvertKit from email address instead of your Gmail account. You can get an email address for your domain name using Google Apps for Work or through your domain host.
Once you’ve secured your new email address, log into your ConvertKit admin page (found by clicking on Account in the menu bar and heading to the reply-to field to make your changes) and update your primary email to ensure that your emails will not be bounced by Google!
Note: In ConvertKit the reply-to IS the from email address. You only need to change this one field to update everywhere.
