Custom Tracking Domains


Link tracking is the process by which ReachMail records which subscribers clicked on links in your messages. When link tracking is enabled in a campaign, the links in the mailing are aliased with unique tracking links. When clicked, the subscriber will be directed to their final destination via one of ReachMail's servers and a 'click' will be recorded for that link. You'll see information on clicked links in all mailing reports.

Using custom tracking domains in the link tracking process allow you to set a preferred domain that will act as the alias for the tracked links.

From here you can click on Set Account Tracking Domain and enter in the domain you would like to setup as your tracking domain. The Verification Status column will highlight red if there is a problem with the verification process. You can use the icons on the side to enable, disable, and re-verify the domain.
