Review on testmail.app by Michael Moonin

I like how easy it is to write tests with this app, and how they've made it very flexible by allowing you to run tests in parallel or serially. It's also good that they have a free tier which allows you to try it out before committing to the pro version. There are some things in their UI which could be improved. For example, the "send" button should not change color when the user has already sent an email - that makes it look really bad. You can't run multiple tests at once, so if you want to run a lot of tests at the same time, you'll need to keep switching back to the main screen. I'm using this to automate my end-to-end testing process. Sometimes I find myself manually clicking around in the different screens to make sure everything looks correct. This saves me time.
