Postmark costs money, Mailgun does not.

Postmark is free up to 100 mails / month. But mail deliverability issues are a hell that I'm happy to pay a small fee to avoid.

Do they have an overage charge for the free 100/month, like the 1.25/1000 they list for their non-free use? So you could be free most of the time with the occasional 1.25 charge if you have a busy month?

Unfortunately I don't think so. :(

> We offer a Free Trial plan for testing purposes only. The Trial is limited to 100 emails a month with no overages allowed.

The free tier of Mailgun has significant delivery problems because those servers have a poor spam reputation.
