I received my first message on Monday (after ATL-PDX on Sunday) Congratulations!
You've earned Silver Medallion® Status through January 31, 2021, with Reclaim My Status.
I should hit the AMEX waiver on this trip, and I believe reach Gold after this trip and ATL-LAX-ATL in the next two weeks.
Depending on some details I'll probably hit the Diamond threshold, but I shouldn't end up being eligible for it, though I wouldn't complain. The funny thing I realized is that I'll actually likely hit the PM threshold naturally on the same flight that I reclaim it so I don't have any clue what message I'll receive.
