Custom tracking domain
Also called: Branded tracking domain, Tracking CNAME
A custom tracking domain is a subdomain of your own (for example `links.yourdomain.com`) that tracked links and open images use, instead of the sending tool’s shared domain.
How it affects cold email
With a shared tracking domain, your links carry the reputation of every other sender using it. Your own subdomain keeps link reputation tied to you and makes links match the sender’s domain.
How Inboxed handles it
- Set it in Settings by adding a CNAME record on your domain that points at Inboxed. Tracked links and the open image then use that domain. Without one, tracking uses the Inboxed app’s address.
