Update: Since publishing this post, we’ve received information that while both Gmail and Microsoft will both update their DMARC policies this year, both policy updates will likely happen closer to the end of 2016. It never hurts to be ahead of the game though, so go ahead and ensure you’re email program is prepared sooner than later. Happy June! You may have heard rumblings of it, but DMARC changes from major inbox providers Microsoft and Gmail are about to shake up things in the world of email authentication. (Asking yourself, “What is DMARC?” Check out this post.) Both Microsoft and Gmail have reported that changes to their DMARC policies will be happening “in June” of this year and unfortunately, haven’t provided more detail since.
