Custom Tracking Domains
Set up a custom tracking domain for better email deliverability:
Why Custom Tracking Domains:
- By default, the open/click tracking and unsubscribe links in your cold emails use WarmySender's shared domain
- A custom domain (e.g., track.yourdomain.com) improves deliverability because the tracking links match your sending domain
- Email providers are less likely to flag emails with matching domains as suspicious
Setup Steps:
1) Go to Settings > Tracking Domains
2) Click 'Add Domain' and enter your tracking subdomain (e.g., track.yourdomain.com)
3) The system shows the CNAME target you need to add: track.warmysender.com
4) Go to your DNS provider and create a CNAME record:
- Name/Host: track (or your chosen subdomain)
- Value/Target: track.warmysender.com
- TTL: 3600 (or default)
5) Wait for DNS propagation (can take up to 48 hours, usually faster)
6) Click 'Verify' in WarmySender. Verification confirms your domain is fully live — that it resolves AND securely serves your tracking links end to end — not just that the DNS record exists.
Status Values:
- Pending — added but not yet confirmed live
- Verified — confirmed live; your campaigns now use your domain for open/click/unsubscribe links
- Error — the domain isn't resolving or serving correctly yet (fix the CNAME and re-verify)
Automatic fallback (your sends are always safe): once a domain is Verified, WarmySender keeps checking that it stays healthy. If a custom domain is ever removed, or its DNS changes and it stops working, your campaigns automatically fall back to our default domain and keep sending without interruption — a broken tracking domain can never stop your emails from going out.
You can set up multiple tracking domains. Tracking domains are managed per workspace.
Best Practice: Use a subdomain of your sending domain (e.g., if you send from @acme.com, use track.acme.com).
