We use Mailgun. It is similar to MailChimp--it is really simple and easy to set up. It’s free and more customizable for developers.

We used to use Mandrill, which merged into MailChimp, but we’ve moved transactional emails to Mailgun and that’s been working well for us.

Mailgun’s users run the gamut in terms of size and growth stage, but all have the high-level development skills (or staff) to be able to use the solution to its fullest.
Mailgun charges by individual email, each costing a fraction of a fraction of a cent. The first 10,000 emails are free; the next 500,000 are $0.0005 per email; the next 1 million are $0.00035; the next 5 million are $0.00015; and anything beyond that is $0.0001. Simple, right?
