Email API (Application Program Interface) is a powerful tool that enables developers to send and receive emails from their applications. It serves as an interface between two separate applications and simplifies the process of sending and receiving emails.

An Email API works by receiving requests from your application and translating them into commands that the SMTP server understands. It then sends the request to the SMTP server, which handles the actual task of delivering the message. The Email API will then take care of any responses it gets from the SMTP server and pass them back to your application.

Apart from simplifying the process of sending and receiving emails, Email API also provides additional features such as tracking messages or customizing emails. This makes them very useful for developers.
