It's also difficult to find providers for competetive large-scale non-transactional emails, i.e. marketing and newsletter mails.

None comes close to AWS, closest comes are messageflow (PL), elasticemail (PL), brevo (FR). Other players like Scaleway TEM (FR) and Lettermint (NL) don't offer non-transactional.

AWS SES does not work for me at all, the sending success rate is really bad.
