Stay informed to safeguard your digital communications effectively and maintain trust with your recipients. Let us delve more about this!

What is DKIM Cname?

What is DKIM Cname?

A DKIM CNAME record (short for Canonical Name record) is a type of DNS record that associates an alias with the actual domain name it represents.

Typically, CNAME records are used to link subdomains like www or mail to the domain where their content is hosted. For instance, a CNAME record can connect the web address to the actual website for the domain

Instead of directly adding the public key to the DNS as a TXT record, which was the traditional method, some email service providers offer the option to publish the DKIM public key using a CNAME record.

What is the difference between Cname and TXT record?

CNAME redirects one domain to another, while TXT stores text information about a domain. They are both types of DNS (Domain Name System) records used to manage domain names, but they serve different purposes:

FeatureCNAME RecordTXT Record
PurposeAlias one domain name to anotherStore arbitrary text-based information associated with a domain
UsageDomain aliasing, redirectionDomain ownership verification, email authentication (SPF, DKIM, DMARC), providing descriptive information points to example.comSPF record: "v=spf1 ~all"
ImplementationRedirects requests from one domain to anotherStores text-based data for various purposes

In summary, while both CNAME and TXT records are essential components of DNS management, CNAME records are used for domain aliasing and redirection, whereas TXT records are used for storing textual information associated with a domain, such as verification, authentication, or descriptive data.

How to Set up CNAME Records?

To update your domain’s DNS records, you might need to add a CNAME record through your domain host. This is often necessary for tasks such as domain verification or password resets, and it’s also common when mapping your website to a new location.

Step 1: Access your Domain Host

Identify your domain host. Next, open a new tab or window in your browser and log in to your domain host’s website.

Step 2: Obtain your unique CNAME record

You receive a distinctive CNAME record for your domain upon setting up Google Workspace or resetting your admin password.

If you’re unfamiliar with CNAME records, reach out to your domain host for assistance. You can utilize the provided email template when contacting their support team.

To add the CNAME record to your domain host, adhere to the following steps. Refer to your domain host’s documentation for more detailed guidance:

  1. Navigate to your domain’s DNS records.
  2. Introduce a new record into your DNS settings, specifying CNAME as the record type.
  3. Return to the initial window or tab and copy the contents of the Label/Host field.
  4. Paste the copied contents into the Label or Host field within your DNS records.
  5. Go back to the original window or tab and copy the contents of the Destination/Target field.
  6. Paste the copied contents into the Destination or Target field within your DNS records.

Your record should resemble one of the tables below:

Why DKIM CNAME is Important?

1. Email Deliverability

Email Deliverability

Many email providers use DKIM authentication as a factor in determining whether an email should be delivered to the recipient’s inbox, spam folder, or rejected altogether. Without a valid DKIM Cname, emails may be more likely to be marked as spam or rejected by recipient servers.

2. Protection Against Spoofing

Protection Against Spoofing

DKIM helps prevent email spoofing, where malicious actors forge the sender’s email address to trick recipients into believing the message is from a legitimate source. By validating the DKIM cname, recipient servers can confirm that the email actually originated from the stated sender domain.

3. Message Integrity

DKIM ensures that email messages haven’t been altered or modified in transit. If a message’s DKIM cname fails validation, it indicates that the message may have been tampered with, and the recipient server can take appropriate action, such as quarantining or rejecting the message.

4. Reputation and Trust

Implementing DKIM Cname demonstrates to email providers that you take measures to authenticate your email messages, which can positively impact your sender reputation. A good sender reputation improves the chances of your emails being delivered to recipients’ inboxes and not being flagged as spam.

Next Crucial Step after Setting Up DKIM Cname
