MailCatcher is a development software and application tool that allows developers to create, test, and debug emails. It is a simple and lightweight tool that allows developers to quickly and easily test their applications with emails. By using MailCatcher, developers can easily send and receive emails without having to configure a separate mail server. It also makes it easier for developers to debug and track down email related issues. MailCatcher also has features that allow it to be used in a production environment, such as email address whitelisting, anti-spam and virus protection, and email forwarding.
The REST API to verify sent email is a nice feature.
