By default, your WordPress site will send out emails from username@servername. If you’re only using them for your notifications, this is fine, but if you’re sending them to customers, you may wish to send them from an address at your domain. Here are the steps you need to make that happen.

Please follow this guide to create an email address – ensure you take note of the password.

Test your settings

Enter an email account you receive mail on along with a subject and brief message then send the test email. Check that everything appears correctly (and that you receive the email) and then you’re all done!
