I have used my IP for 5+ years. Too scared to switch hosting provider for exactly this reason.

I disagree on your your point of letting go of emails. What’s the alternative to reach out to my users? Social media? they have much more vendor lock-in.

I also disagree on the the “protocl outlived its usefulness” part. Yes, it has its warts. but so do everything else, eventually. I have not seen anything fundamentally better and widely adopted at the planet scale.

I use local SMTP server (exim4). It is not easy; You need to have all the SPF/DKIM/DMARC crap setup, and your hosting company allows outbound SMTP.

Some email providers still block my emails though. However, all cheap email senders have the same problem in one way or the other. With your own IP and a fully controlled setup, at least I can fill out complain form.

Previous discussion thread here:

Yeah, there are certainly tradeoffs with self hosting Email. I don’t mind the occasional issue, and IMO, it’s important for the continued federation/democratization of Email that enough people choose to self-host so as to discourage bad practices, such as whitelisting senders.

Mailjet has a free plan with 6k emails/m (200/day)

Resend’s free tier is a bit worse than Mailjet (3k emails per month) but their paid plans seem cheaper. You get 50k emails/month for $20.
