Learn How To Use The CNAME Checker:

What Are CNAME Records?

A CNAME checker reads the CNAME record on a domain or subdomain and shows you where it points. A CNAME, short for Canonical Name, is a DNS record that points one domain name at another instead of at an IP address. It is used for tracking domains, custom links, email setup, and connecting third-party services. The checker pulls the record and shows the target it resolves to, so you can confirm a subdomain is pointed where it should be and catch entries that resolve incorrectly.

How the CNAME Checker Works?

1. Enter the domain or subdomain: Type the address you want to inspect and run the lookup.

‍2. We query DNS: The tool retrieves the CNAME record for that name.

‍3. We show the target: You see exactly where the CNAME points and whether it resolves.

‍4. You confirm the setup: Use the result to verify a tracking domain or connected service is pointed right.

Why It Matters?
‍

Keep Your Tracking Working

Custom tracking domains for cold email rely on CNAME records. If the record points to the wrong place or has a typo, your open and click tracking breaks and links can look untrustworthy. Checking the CNAME confirms your tracking domain is set up correctly before you send.

Catch Misconfigurations Early

A stale or mistyped CNAME fails silently. The page or service it should connect just does not work, with no clear error. The checker shows the live target so you can spot a wrong or outdated entry immediately.

Verify Connected Services

Many third-party services ask you to add a CNAME to verify ownership or route traffic. The checker confirms the record resolves to the right target, so you know the connection will work before you rely on it.

What is a CNAME record?

A CNAME record points one domain or subdomain at another domain name instead of an IP address. It is used for tracking domains, custom links, and connecting third-party services.

Why does my CNAME matter for cold email?

Custom tracking domains use CNAME records. If the record is wrong, your open and click tracking breaks and links can appear untrustworthy. Checking it confirms your tracking domain is pointed correctly.

Why can't I add a CNAME at my root domain?

A root domain usually cannot use a CNAME because it conflicts with other required records. Use a subdomain for CNAMEs, or use an ALIAS or ANAME record if your DNS host supports one at the root.

Is CNAME record checker free?

Yes! Using Salesforge’s CNAME Record Checker is completely free.

What is the difference between a CNAME and an A record?

An A record points a domain directly to an IP address. A CNAME points a domain to another domain name, which then resolves to an IP. CNAMEs are used to alias one name to another, such as a tracking subdomain to a provider's domain.

Why is my CNAME not resolving?

Common causes are a typo in the target, the record not having propagated yet, or a conflicting record on the same name. The checker shows the live target so you can confirm whether the record exists and points where it should.
