Domain Verification

Domain Verification in Zoho

You need to verify the domain added in Zoho, to ensure that it is a valid domain and you have the required privileges in the domain to manage the email services. 

Domain Verification is an essential step to ensure that the domain you added is Valid, Not expired and the user who added the domain has the required privileges to access DNS and decide about the email service for the domain. It is a mandatory step to ensure that the domain is not Spoofed domain and to prevent any loss of service due to the misuse of domain names.

The steps like DNS access is needed not only to verify the domain but also to configure email delivery for the domain. 

Zoho Mail provides one-click verification and manual verification methods from which you can choose.

One-click Verification:

In the one-click verification method, you can verify your domain in few simple steps. Once you reach the Domain Verification step, select the One-click Verification option, login to your DNS provider and authenticate your Zoho Mail account to use your DNS provider. Zoho Mail will add the DNS record to verify your domain.

Currently, one-click verification isavailable only for 1 & 1 domain holders. Click here to know more.

​Manual Verification:

If you are opting for manual verification, you can verify using any of the below mentioned methods:

  • CNAME Method -  Add a unique 'CNAME' record specified by us in the domain's DNS Manager.
  • TXT Record Method - Add a specific TXT Record, in the given format in the domain's DNS Manager 
  • HTML Method - Upload the given HTML file in the specific folder as provided in our instructions, under the root of your website. 

The detailed instructions to verify your domain by CNAME Method for some popular DNS hosts, are available in the above links. 

In some cases, you might have registered the domain with a provider but changed the NS (Name Server) hosting to a different provider. In this case, the CNAME/ TXT should be added in your new DNS host. The DNS records like MX, CNAME are returned by your Name Servers and are available with your DNS Host. You can get the help of your DNS Registrar/ DNS host to get assistance in this. 

DNS Switch after Verification:

Once you have verified the domain, the CNAME (zb code zb***** ) or the HTML file can be removed and is no longer necessary. If your domain is already verified, and you switch your DNS provider, you need not add the zb code or CNAME again. You should definitely check the MX records of your domain after you change the DNS. Most of the DNS providers reset the MX records during the DNS change or switch. 

CNAME Method
