Important Points

• Make sure to configure the Mail extension with the correct SMTP server details and login credentials.
• Use the Message class provided by the Mail extension to construct the email message before sending it.
• The send method of the Mail extension is used to actually send the email.

Summary

The Mail extension in Flask provides an easy-to-use interface for sending emails from your Flask application. By providing the SMTP server details and login credentials, you can quickly send emails to one or more recipients straight from your Flask app.
