Your server comes preinstalled as a send only SMTP server, allowing you to send unlimited emails from the server from any account you need. Simply setup an email in the WordPress plugin or application and send away.
To make sure your emails reach their destination, its recommended to:
- Use SPF and DKIM records to prevent spoofing and improve email reliability and delivery.
- Make sure the PTR record for your server matches the hostname being used by the mail server.
