Tracking domain checker for cold email

Check whether a branded cold email tracking domain has the DNS and HTTPS basics it needs before campaign links go live.

This checks tracking-domain CNAME, DNS, HTTPS, and redirect handoff for one domain. For a real launch verdict, run every domain, inbox, and tracking domain through the full QA pass.

Runs live in your browser via public DNS. Nothing is stored.

Links break after DNS looks green

Tracking domains fail in a specific way. The CNAME can resolve, the sending tool can show a setup check, and the actual HTTPS link can still fail for prospects.

This checker verifies the branded tracking host from the outside. Use it before launch, after changing sending tools, and before reusing a client workspace.

What to fix before launch

A missing CNAME means the tracking host is not pointed at the sending tool. A DNS-only result means the target exists, but HTTPS still needs review. A failed HTTPS result is a launch blocker for tracked links.

For client signoff, pair this with the sending-domain checks. OutboundQA runs tracking CNAME, SSL, redirect, blacklist, and sender checks across the full workspace.

How to read the result

A pass means the tracking host has a CNAME target, resolves, and accepted HTTPS from the browser. A warning means the link may work, but one setup detail needs review. A fail means links or opens should not depend on this host yet.

What this check does not catch

A passing tracking-domain CNAME, DNS, HTTPS, and redirect handoff lookup is useful, but it is not launch signoff. Cold email campaigns still fail when adjacent records, tracking domains, or inbox-level settings are broken.

Setup guides for this check

Read the setup notes behind this result, then verify the neighboring records before launch.

Need to check a full outbound workspace?

OutboundQA checks every domain, inbox, and tracking domain in the workspace, then gives you a shareable report with a Ready, Needs Fix, or Do Not Launch verdict.

Cold email launch checks to run next

Use this result as one checkpoint in the launch flow. Then verify the neighboring records and run the combined domain check before the outbound launch goes live.

SPF Checker

Look up a domain's SPF record and count its DNS lookups against the limit of 10.

DMARC Checker

Look up a domain's DMARC record and read its policy in plain English.

DKIM Checker

Look up a domain's DKIM selector and confirm the public key exists.

Auth Checker

Run SPF, DKIM, and DMARC together for a sending domain before launch.

MX Checker

Look up a domain's MX records and detect the mail provider.

Blacklist Checker

Check a domain and sampled mail server IPs against domain and email blocklists.

Reputation Checker

Check observable cold email reputation risks across age, blacklist, authentication, MX, and HTTPS signals.

Deliverability Checker

Check observable cold email infrastructure readiness across MX, SPF, DKIM, DMARC, blacklist, age, tracking-domain, and SMTP egress identity signals.

Receiver Checker

Check observable Gmail, Yahoo, and Microsoft sender requirements from public DNS and optional pasted message headers.

Recipient Preflight

Paste emails or domains and classify MX provider, free inboxes, security gateways, SPF, DMARC, and receive-mail readiness.

MTA-STS Checker

Check MTA-STS and TLS-RPT records for inbound mail security posture before a cold email launch.

PTR/rDNS Checker

Check a custom SMTP egress IP for PTR, reverse DNS, and forward-confirmed rDNS before launch.

Questions

A tracking domain is the branded host used for click and open tracking links, such as links.yourdomain.com. It usually points to the sending tool with a CNAME.

It checks whether the tracking host has a CNAME target, resolves in DNS, accepts HTTPS in the browser, and appears to hand off to the tracking service.

Prospects, browsers, and link scanners open tracking URLs over HTTPS. A certificate failure can turn a real click into a browser warning or a campaign risk.

No. Tracking is only the Links part of launch QA. A real signoff also checks sending-domain authentication, inbox setup, blacklist status, domain age, and receiver requirements.
