I have a list of email subscribers. I was using an email service, but am not happy with it.
What happens if a mailing software is set up on a new server, that has never sent email before, but the software sends email through an SMTP service like Amazon SES or Sendgrid?
Would a server warm up process still need to take place, where I start sending emails a few at a time?
Or could I start sending a lot of emails right away?
Thanks in advance!
