SMTP Testing Tool

About the tool

The Simple Mail Transfer Protocol (SMTP) is the protocol used to send emails over the Internet. It is a text-based protocol that uses commands and responses to communicate with the email server.

This tool is designed to help you test SMTP communication with email servers by sending test emails. It is helpful if you are having trouble sending or receiving messages with your email server or if you are testing a custom messaging server implementation.
