Troubleshooting System Email

Problems with your system email can prevent you from sending email to clients or connecting to your mail provider.

Mail Providers

You can choose from several supported mail providers for your WHMCS installation, including Google™, Mailgun, Microsoft®, PHP Mail, SendGrid, SMTP, or SparkPost.
