Thanks! In my personal experience, I've had success delivering to the inboxes of Gmail, Outlook, and Zoho Mail with SES. However, my newsletter is entirely opt-in on my website. When I signed up for SES, there was a human review as to what I would be sending. So, I think Amazon understands spam is an issue, too.

Listmonk supports many email providers though, if your needs outgrow SES.
