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.

Came across a nice test SMTP server at @Mailtrap today. Seems like a lovely little service to use, free plan and price plans are very reasonable. No more dev junk in my mailbox 🙂

I’ve had a hard time setting up an SMTP server for some testing purposes because of sender authentication. Thanks to @Mailtrap, it doesn’t require such complicated settings, and everything works perfectly! Mailtrap solves my problem in 5 minutes.
