Custom tracking domain
Set up branded tracking for opens and links.
A custom tracking domain keeps tracking links aligned with your sending domain instead of a shared tracking domain.
What this helps you do
A custom tracking domain keeps tracking links aligned with your sending domain instead of a shared tracking domain.
Recommended workflow in Outlio
Choose a subdomain such as track.yourdomain.com.
Add the CNAME record shown by Outlio or your tracking setup.
Keep the record DNS-only if your DNS host has proxy controls.
Enable custom tracking for the account or campaign.
Send a preview and click the tracked link to confirm it resolves.
Quality checks
- Use a subdomain, not the root domain.
- Do not use the same subdomain for another tool.
- If deliverability matters more than open data, consider disabling open tracking.
Common mistakes to avoid
- Proxying the tracking record through Cloudflare when it should resolve directly.
- Using a subdomain already used for a website.
Done well, this should leave you with
A cleaner Outlio setup, fewer avoidable campaign issues, and a more reliable path from setup to replies.
