MAGY Mandates: Microsoft Sender Requirements and the Bigger Picture

Last week, yours truly (Al Iverson from Valimail) was joined by my friend Jennifer Nespola Lantz from Kickbox for a deep dive webinar on Microsoft's new bulk sender requirements and how they fit into the bigger "MAGY" (Microsoft, Apple, Gmail, and Yahoo) landscape and overall email ecosystem.

The good news: If you're already doing the right things to meet Yahoo and Gmail's requirements, you're most of the way there. But Microsoft's approach does include a few gotchas that we walked through in detail.

Jen and I talked about:

• SPF, DKIM, and DMARC requirements, and passing versus alignment
• Permission and best practices, engagement and feedback
• What exactly Microsoft means by P2 sender address (and what's a compliant one)
• Why email forwarding breaks things
• Spamtrap realities and why verification (while useful) wasn't made for spamtrap removal
• How MAGY (+ Cloudflare) requirements are converging, and what that means for the email marketing campaigns you send

We also dug into the quirks and features, bugs and stumbles people run into with DKIM and DMARC failures, list hygiene expectations, subdomain reputation, and what “good mail” actually looks like from the mailbox provider's point of view.

It was a fun session, with a little bit of practical advice, a few nerdy detours, and occasional attempts at dry humor. Find the video above or linked here.

Thanks again to my friend Jen for joining me on this adventure (and thanks to all of you who attended). And if you missed it, but you're a sender or ESP trying to make sense of MAGY mandates, I hope you find this recording useful!
