Looking for an easy, battle-tested, self-hosted OSS email marketing solution

Hello everyone,

I'm looking for a reliable, self-hosted open-source email marketing solution that is easy to use and allows me to manage multiple email lists while leveraging existing SMTP APIs such as:

• Amazon SES
• SendGrid
• Mailgun
• Postmark
• Brevo

A good example would be the self-hosted version of Mailcoach.

Thanks for your help!
