Tracking CNAME issues
Resolve conflicts on the link tracking subdomain Reloop uses for clicks and opens.
Reloop typically expects:
| Type | Host | Value |
|---|---|---|
| CNAME | link | link.reloop.sh |
So link.yourdomain.com resolves to Reloop’s tracking edge.
Symptoms
- Tracking record shows failed in Reloop
- Another app already uses
link.yourdomain.com - Provider error when saving the CNAME
Fixes
- Remove or rename the old
linkrecord if you no longer need it. - If you must keep
linkfor something else, change Reloop’s tracking subdomain in domain settings (when available) and publish the new host. - Ensure no A/AAAA sits on the same host as the CNAME.
- On Cloudflare, use DNS only for the tracking CNAME unless Reloop docs say otherwise.
