Engage sends two general types of email messages to users. First, there are system-triggered notifications, such as invitations, confirmations, status updates, etc…. Second, there are user-initiated mass messages in the form of mail relays.

To increase mail delivery rates through the varied spam-protection protocols in use by our campuses, Campus Labs works with a third-party email service called Mailgun. Mailgun provides tools that help our member campus email screening systems see these messages positively while providing redundancy and error handling for our development staff. 

Since we’ve implemented Mailgun’s email deliverability service, many member campuses have not had to take any action to successfully receive mail from Engage. However, from time-to-time, a member campus’ email screening system may be tuned more sensitively, necessitating campus IT to allowlist traffic from our email servers. 

Allowlisting is the process of instructing an email screening system to trust all messages sent from a specific IP address and/or domain. Although common, allowlisting is a crude method to allow this traffic and should be avoided unless necessary, to align with anti-SPAM best practices. 

If you have questions or would like to obtain our IP and domain information for allowlisting, please contact our support team. 

Since every campus screening system is unique, we recommend that you test both system-generated and user-generated messaging from Engage before initiating an allowlist request with your IT team; there’s a good chance you will not need to use allowlisting!
