May I suggest Mailjet (which is now part of Sinch just like Mailgun)? Their Ruby gem is very memory inefficient, so Courrier could be a solution for many use cases.

@svoop sure, go for it! Iirc I tried adding them but could not verify them because of an strenuous spam checks.

@eelcoj Sounds like the kind of thing you run into with Mailjet. 🙈 We're currently using their problematic gem (because we also have to manage our newsletter campaigns using the API), so there's no urge to swap the transactionals adapter. After reading about Courrier on one of my Ruby feeds, the suggestion was merely to mention Mailjet in case you don't know them... which obviously isn't the case. If we switch to Courrier at some point, I'll have go for sure.

Hi! I'd like to add the MailerSend provider, following the existing Brevo provider pattern. 🙌

Following up on MailerSend (#53) — I'd like to take the two remaining providers as well: SMTP.com and Mailtrap. Both are ready and I'll open them as separate PRs so they can be reviewed independently.
