I am testing Mailtrap last weeks. You can send emails from your domain for free. They allow 1000 mails/month. It is quite ok. It can be used with good old SMTP connection or via API.

I love @Mailtrap. It removes all the asshole of configuring email servers in test environments. Great service! Is totally worth your money!

One thing we started using recently is @Mailtrap for our dev & staging environments. We were previously either turning email sending entirely off for staging or running SES + whitelist. Turns out, having a fake SMTP mailbox is great and you can test better with it.
