What is Magento 2 Mail SMTP?

A Simple Mail Transfer Protocol (SMTP) allows you to send emails through an external SMTP server rather than the default Magento email server.

This mail server ensures better mail delivery and reduces the likelihood of your emails being flagged as spam. It supports popular email services like Gmail, Yahoo, and Outlook. Logs emails can be sent for better tracking and troubleshooting. It also provides flexible SMTP settings for advanced configurations.
