Mailtrain VS Listmonk

I have used mailtrain for a while to send out a small newsletter with articles from an rss feed, but mailtrain does not see much development anymore.

In many cases an email group could be defined a simply as a forwarder with multiple recipients configured for it. For more complexity, I really like this: https://github.com/Mailtrain-org/mailtrain

Mailtrain documentation is lacking big time

I have mainly name and email fields in the newsletter signup and there is no verification. Then I manually blacklisted all the bots in the email service Listmonk.

Listmonk – An open-source alternative to Mailchimp just released version 3. It’s great as a stand-alone newsletter. Also seems like a low lift for capturing leads for side projects.

Here is another great self hosted solution that I came across. Really high performance (written in Go). No affiliation but well done open source product.

When I searched for this I had a very hard time finding a right answer because all the results were SEO blogs advertising their newsletter services (Mailchimp, Convertkit, etc.), which is not the same thing.

So I wrote this overview covering all the options I found. Additional input is welcome.

Even though Listmonk seems like the best free & open source option, there aren't many guides for it and the documentation is quite limited. So [I've been having trouble getting it running on a CentOS server](https://github.com/knadh/listmonk/issues/1004#issuecomment-1...).

It's a shame that it seems to be used by thousands of people but almost no one bothers to create guides or improve the docs.
