Tracking domain verification failed
Custom tracking domains require a CNAME DNS record pointing to track.warmysender.com, on a SUBDOMAIN of a domain you own. Common issues: 0) 'A tracking domain must be a subdomain' — you entered your bare domain (acme.com) rather than a subdomain (track.acme.com). Bare domains are refused when you add them, because pointing your bare domain at us would take your own website and email routing offline; accept the suggested track. version, or type your own subdomain. 1) 'No CNAME record found' — You haven't added the DNS record yet, or it hasn't propagated. Add a CNAME record for your chosen subdomain (e.g., track.yourdomain.com) pointing to track.warmysender.com. 2) 'CNAME record points to wrong target' — Your CNAME points somewhere else. Update it to point to track.warmysender.com exactly. 3) DNS propagation can take up to 48 hours — try verifying again later. 4) Some DNS providers require you to enter the subdomain only (e.g., 'track') without the full domain. 5) Make sure you don't have conflicting A records on the same subdomain. After verification succeeds, select the tracking domain in your campaign settings to use it for open and click tracking.
