What I need:
- Focus on transactional email.
- Support for inbound emails, sent to us via POST webhook.
- Good developer documentation and overall good product obviously.
- DKIM, SPF and DMARC support.
- Decent UI to troubleshoot delivery problems, i.e. easy to inspect the status for any one email.
- Happy to pay for it, price not a big factor.
I've looked at Mailgun, but happy to hear other suggestions.
I prefer SES for a number of reasons:
- The price is about the best you will get.
- You can DKIM sign messages yourself if you want (although IIRC they remove the ability to verify your domain with DKIM from the console recently. Hopefully they don't drop this support).
- Pay as you go Pricing means that you don't pay for unused quota.
- Regional service may be more complicated but in theory you should be able to tolerate localized issues. The main downside is that you need to verify in each region which is very annoying.
wouldn't you know it, we transferred them to postmark...
