Get Started Now!WHMCS can send emails without any additional configuration using PHP mail(). While this works in most cases, other mail providers may give you a better experience and access to additional features.
In addition to the existing SMTP support, WHMCS 8.0 added support for Mailgun, SendGrid, SparkPost, and Google OAuth with SMTP. WHMCS 8.6 and later also include Microsoft services as separate mail provider options. For more information, see:
