The title seems a bit dramatic but I can see how this sort of stuff would throw anyone without a history of network or systems administration for a loop.

This is one thing I really enjoyed about setting up ProtonMail with my personal domain. They make it really simple to validate that SPF, DKIM, and DMARC are set up properly.

I didn't realise that ProtonMail had DMARC built in. I'm kind of surprised more email providers aren't including DMARC report analysis out-of-the-box, to be honest.

If Google Workspace/G Suite started pushing admins to use DMARC, and provided tools to make it easy, so many more domains would be protected, particularly in startup world.

Ok, we've changed it to the (slightly less dramatic?) subtitle. Not sure which is the better choice here...

I agree about Protonmail. Never used their service, helped a client straighten their records for a project. No issues.

Tutanota are just as straightforward, but they're both in the security game so not much of a surprise there.
