What is Custom URL Tracking?
Custom URL tracking replaces ContactMonkey's default tracking domains with your own branded subdomain in all email links. Instead of links starting with contactmonkey.com or regional variants, they'll use your organization's domain (e.g., comm.yourcompany.com).
Getting Started
Prerequisites:
- Enterprise plan subscription
- Subdomain ready for configuration
- IT/Security team available for DNS setup
Next Steps:
- Contact your Customer Success Manager to purchase this feature
- Our Technical Support team will guide you through the implementation process
- Work with your IT team to configure DNS settings
- Add your custom URL to your organization's security allowlist
Why Use Custom URL Tracking?
Brand Consistency
Maintain your organization's branding throughout email communications. Links appear as internal resources rather than third-party tracking URLs.
Simplified Security Management
- Keep your existing security allowlists without adding ContactMonkey domains
- Eliminate the need to update security policies across Microsoft Defender, Mimecast, Proofpoint, or SafeLinks
- Reduce "ghost clicks" from security scanning tools that inflate campaign statistics
Note: You'll still need to add your custom URL subdomain to your organization's allowlist.
How It Works
Before Custom URL
When you send a tracked email, ContactMonkey adds tracking parameters to your links:
https://contactmonkey.com/api/v1/tracker?cm_session=a99999a9-aa99-999a-99a9-a9999aa9a9a9&cs=9a99aa99-a99a-9aaa-aaaa-a99aaaaa99aa&cm_destination=https://www.google.com/After Custom URL
The same tracking functionality uses your branded subdomain:
https://comm.yourcompany.com/api/v1/tracker?cm_session=a99999a9-aa99-999a-99a9-a9999aa9a9a9&cs=9a99aa99-a99a-9aaa-aaaa-a99aaaaa99aa&cm_destination=https://www.google.com/All tracking features remain fully functional—only the domain changes.
Subdomain Requirements
Your custom URL must be a subdomain of your organization's main domain.
Examples:
- Main domain:
example.com - Valid subdomains:
newsletters.example.com,internalcomms.example.com,cm.example.com
Regional Considerations
ContactMonkey uses different tracking domains based on your data hosting region. If your organization sends emails from multiple regions, you may need custom URL entries for each.
ContactMonkey Tracking Domains by Region:
