This certainly seems to be the consensus about self hosting email, but but I'm now convinced otherwise.

I send a couple newsletters (one tech related, other for marketing for a coffee shop/bakery I own), and it was fairly easy to land on inboxes. Now, I don't know with a 100% certainty that they were delivered, but if DMARC records and bounces are anything to go by, self hosted emails aren't all that hard.

When you buy a VPS, it helps to check if the IP you receive is already blacklisted. After that, it's easy to use some outside service to monitor DMARC responses and blacklist. There are about 40 black list databases. My domains and the IP address are on none of them.
