The problem with mailtrain is according to them it's not viable to use in production. There's also no tests and very little documentation.

I can get around that but the main thing preventing me from using it is there's no success stories associated to the application.

Sendy has dozens of unbiased blog posts, and even some posts where people are sending millions of e-mails without issues. That instills a lot of confidence in using it.

You would have to be a madman to trust an untrusted application with managing your email subscribers.

Just for the record, Mailtrain is used in production by several marketers with very large lists (from hundred thousand subscribers to a million subscribers) and Mailtrain seems to work fine for them

Is there anything to read that's public where those marketers comment about using it?

Have any of them done any audits on the code base and traced all incoming requests through Mailtrain vs their SES backend to ensure everything was delivered as expected?
