I switched from Postmark to @Mailtrap for sending ~1M emails per month for my SaaS. It’s cheaper and and has a better stats design. Also, their team is very nice and helped me to improve open and bounce rates.

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. https://mailtrap.io/

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.
