Yet another happy Postmark customer here. They're the only transactional email provider I've found who keeps full text logs of your outgoing mails (for a couple weeks) - in a complex "Enterprise" environment I cannot overstate how helpful having one place that always logs the mail that actually went out to the customer is. No matter what the sending system may have logged or failed to log.

Also their deliverability is excellent and when there are deliverability issues, it's easy to find exactly why. The logs also surface the info we need to prove what actually happened during a nondelivery event. ("Here is the actual log line from your MX server rejecting the mail we sent.")

For small near-zero-budget projects, I still use Amazon SES. It's Good Enough for most uses and nobody else with even decent deliverability can touch them on price. All my hobby projects combined are billing well under $1/mo for SES usage.

SES is also decent for some very specific inbound email use cases. If you need to receive email from some system that doesn't have a real webhooks type outbound API, but does have robust email notifications, and send the body to a Lambda function that parses it and makes the API call that system ought to have just made in the first place.. SES is perfect. (And unfortunately all the major systems I work with that process inbound email are stuck needing an IMAP connection - if I was able to use an API based inbound email receipt scheme, and needed to receive mail from various domains, I'd consider Postmark for the better diagnostics and logging.)

Mailgun's logging is great, and includes the full-text of messages.
