After all these years of web development, how have I only JUST started using @Mailtrap. I had heard about it, but never got round to using it. An awesome way of testing emails.

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.
