Do you have questions? If so, we have answers!

Microsoft's newly published updated sender requirements are all everybody has been talking about since they were first shared with the world on April 2nd. If you're not clear on everything, have questions about how it all works, or wondering things like who handles what, me versus my ESP/ISP, does DMARC guarantee inbox placement, what constitutes a bulk sender, what if I send 1:1 email only, what about outbound sales emails, and how do I test for compliance, and more?

If so, then you'll want to come to the Microsoft Sender Requirements Roundtable Session hosted by yours truly (Al Iverson of Valimail) and Alison Gootee of Braze this Friday!

This small audience event will be fully interactive; Alison and I will share a brief overview of current state and our understanding as far as what you need to do to comply, and then we'll take your questions.

This will happen on Friday, April 18th at 12:00 noon US central time on Zoom. Want an invite? Just REPLY TO THIS EMAIL and let me know that you want in, and I'll send you the invite. It's that easy.

As always, thanks for reading! And now, on to the deliverability news!
