Configuring ContactMonkey’s Trusted URLs In Group Policy

If your images are not displaying automatically for your recipients, your IT team may need to add ContactMonkey-specific URLs to your Group Policy to ensure that ContactMonkey is not flagged as an external tool and therefore blocked. 

If these URLs are not added, it can result in some aspects of ContactMonkey being blocked and not performing as expected. This can look like:

  • Emails sent through ContactMonkey appearing as external emails in any capacity 
    • Images not loading automatically
    • [ EXTERNAL ] tag on emails

Applies To:

❌ Gmail ✅ O365 ✅ OWA ✅ COM Add-In


Getting Started

To complete these steps, you will need to have:

  • An IT team member with permission to update Group Policy

What is Group Policy?

Group Policy is a hierarchical infrastructure that allows a network administrator in charge of Microsoft's Active Directory to implement specific configurations for users and computers. Group Policy is primarily a security tool, and can be used to apply security settings to users and computers.
