Ask HN: What's your preferred transactional email provider?

We're currently using SendGrid to handle transactional email for matchist, but they make you get the $80 plan just to use the Parse API.

Seems silly to use them when competitors like Mailgun give you parsing for free and their overall pricing is much cheaper (we don't have a large volume).

Is SendGrid much better at delivery or would I get just as good delivery with a cheaper competitor? What does everybody use?

Thanks!
