Fake SMTP server as a service

In plain words

Fake SMTP Server as a Service is an email testing tool for developers. It provides a fake SMTP server that captures outgoing emails during development and testing, allowing developers to verify email functionality without sending real messages. The service is useful for teams building applications that need email features, letting them test email delivery and formatting in a controlled environment before deployment.
