How to Configure Custom Tracking Domain
A custom tracking domain replaces OutSends' default tracking links with your own branded domain. This prevents link rewriting from triggering spam filters and builds recipient trust.
What you'll need
Before you start, make sure you have the following ready.
- A domain you control (e.g., yourdomain.com)
- Access to your DNS provider
- An OutSends account
Step-by-step guide
Follow these steps to complete the setup.
Choose your tracking subdomain
Create a subdomain like "track.yourdomain.com" or "links.yourdomain.com". Shorter is better for email display.
Add CNAME record
In your DNS provider, add a CNAME record pointing your subdomain to OutSends tracking server. OutSends provides the target value.
Verify in OutSends
Go to Settings > Tracking Domains. Enter your subdomain and click Verify. OutSends checks DNS propagation.
Set as default
Once verified, set your custom domain as the default tracking domain for all campaigns.
Test tracking
Send a test email to yourself. Hover over links to confirm they point to your custom domain.
Tips for best results
Pro tips to get the most out of this setup.
- Use a subdomain, not your root domain — this protects your primary domain reputation
- Verify DNS propagation with tools like whatsmydns.net before verifying in OutSends
- Set up the tracking domain before launching your first campaign
