I’ll point out, this isn’t an ESP only problem. Two of the biggest

actually a bigger problem in my (mostly unfiltered for reasons) inbox
than any ESP.
That is an understatement. Worst part is, I can't get more aggressive
on the filtering for gmail/gapps and o365 sources without running the
risk of catching legit mail from my customers or their customers.
I’m agreeing there is a problem with ESPs and have said so to ESPs
individually and as a group over the last few weeks.
The ESPs are interested in sender reputation. But, in this context,
reputation means “Our mail gets accepted at the ISPs”. In that context
their reputation is fine. They’re not being blocked. Specific customers
may have delivery problems, but a lot of the modern machine learning
filters are very good at blocking the problem customers without blocking
the good ones.
My biggest (well, one of two big) gripe right now with SendGrid is their
apparent lack of bounce handling. I can throw their mail back at their
tagged from addresses with a rejection notice or reject at connection
time and their systems just won't take NO for an answer.
Zoom on the other hand, it seems like they're just letting (at least
this particular spammer that has been spewing for over a year now)
people use their mail systems with a from of no-re...@zoom.us and no
list tagging or any way to unsubscribe or block messages from them.
