Hey guys, I have been attempting a paid list for few weeks now and I need help. The list is 1million and we are sending a onetime email. At first we started with SES then 2 other SMTP providers -- we were suspended by each one after a certain number of emails (150k in total now). On a healthy ip we get a bounce of 10% with spam of 0.5%. I am looking for a smtp provider that can accommodate us or setup our own with ip rotation. Please advise!
