It took me a couple of days to figure out... and now I'm getting messaging that my email is "broken" across a number of sites a few that even refusing to email me even though my DNS is fixed.
Is there any recourse here?
It sounds like the answer is "no, there isn't any recourse because this is sender-specific". In my case (e.g.) SendGrid needs me to be whitelisted again.

For another provider, I was told I had to contact support as I had been "blacklisted" by Sendgrid and they had to issue a request to unblacklist me.
