Every time I’ve thought, “it would be great if it could do this,” Mailtrap already did. It is a polished product from a team that listens. It’s exactly what we need to handle our critical B2B marketplace communications.

Building simplistic things is the hardest, but Mailtrap is just simple. I just throw the documentation into Cursor and it works flawlessly. It stood out with a perfect bucket of features other services charged way more for.

Mailtrap solved a real problem for us. It’s a stable system that provides the visibility our marketing team needs without compromising our high-security infrastructure. It was far easier to turn on than complex cloud providers – our devs are happy.

Mailtrap has been a game changer. Switching was very quick and the UI is super fast and intuitive, it takes much less time than SendGrid. The interface is amazing, always working, and I’m not missing anything from our old tool.

Prior to Mailtrap, testing was a world of pain. Mailtrap has certainly made things a lot easier for our teams. It’s a very well thought out, stable system that does the job.

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/

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

Shout out to @Mailtrap, hands down the best way to handle mail sending in local/test environments.

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.
