For better deliverability it is advised to whitelist the following SMTP server IP addresses in your email server and spam filters settings:

  • 216.157.35.124
  • 50.31.58.66

You may also want to whitelist the campusgroups.com domain as a sender to prevent emails sent from it from being quarantined. If you are also using a custom url you will also want to whitelist the custom domain as well as it may be used to send emails from the platform.
