I had set the SPF, DKIM, DMARC correctly with the with the ESP system, right after I change send out the campagin, I do see all email send/delivered.
Can I immediately change of SPF, DKIM, DMARC?
example change from ESP1 to ESP2's record?
As my understanding, as long msg reach receipient end. Should be no problem to do the changes.
Correct me if I am wrong.
Do share me more detail. TQ
