If your DNS Manager is with Cloudflare, follow the steps below to add CNAME in Cloudflare for verification.

1. Login to your Cloudflare account using the credentials which you used to purchase your domain.
2. Select the domain for which you want to add a TXT record and click DNS.
3. Scroll to DNS Management and click Add Record.
4. From the Type list, select CNAME.
5. Specify Name as the code generated in your Zoho's domain verification page (Example: zb12345678).
6. Specify Target as the value from the CNAME Value/ Points To/ Destination field of your Zoho Mail Admin Console.
7. Set Proxy Status to DNS only.
8. Click Save.
9. The relevant CNAME Records will automatically be applied to your domain.

If your domain's DNS Manager is hosted with Cloudflare, follow the below steps to add MX records for your Domain for email delivery, add SPF and DKIM records to prevent spoofing of your domain email address. 

1. Login to your Cloudflare account using the credentials which you used to purchase your domain.
2. Select the domain for which you want to add a TXT record and click DNS.
3. Scroll to DNS Management and delete any existing MX records.
4. Click Add Record.
5. To add MX Records, select MX from the Type drop-down menu
6. Enter @ in the Name field.
7. In the Mail Server field, enter mx.zoho.com and in the Priority field, select 10 and click Save.
8. Repeat the same steps to add second and third MX records and their priorities.
   

9. To ensure correct email delivery to your domain, only the MX Records provided in the Tools & Configurations section of Admin Console should be used.
    

   MX records

   Host/ Domain	Address/ Mail Server/ MX Entries/ Value	Priority
   @/ Blank/ Domain name	mx.zoho.com	10
   @/ Blank/ Domain name	mx2.zoho.com	20
   @/ Blank/ Domain name	mx3.zoho.com	50

   The MX values in the above table are based on the generic configuration information. For more specific configurations particular for your domain refer to the Tools & Configurations section in the Admin Console.

   Note:

   Depending on your DNS provider, you may need to include a trailing dot(.) at the end of the MX record. We recommend you to go through your DNS provider's support documentation for the exact method to add the MX entries.

10. To add the SPF records, Click ADD record and select TXT from the Type drop-down list.
11. Specify the Name/ Host as "@".

12. In the TXT Value field, enter "v=spf1 include:zohomail.com -all" and click Save.
     

    Note:

    • The values of the records with respect to Cloudflare will be given in the Zoho Mail Admin Console's DNS Mapping page. You can copy-paste the values into the respective fields in the DNS Manager.
    • In case you are using only Zoho Mail to send emails, remove all the other SPF record types from the DNS. Click 'Save Changes' again to save all the changes.
    • Having multiple SPF records will interrupt the SPF check and hence the SPF validation may fail and the emails will end up as Spam in the recipient servers. Learn more.
       
13. To add the DKIM records, locate the option to add a TXT record, then click Add and select TXT from the Type drop-down list.
14. For the Host field, copy the value "zoho._domainkey" (this will be different in the case of a different selector) from Zoho's Domain Setup page and paste it into your domain's DNS page.

15. For the Points to/ Value field, copy the value "v=DKIM1; k=r**; p=***************....****" from Zoho Mail's Domain Setup page and paste it in your domain's DNS page and click Save.
     

    Note:

    It may take anywhere between 4 to 48 hours for your DKIM record to propagate. You can check the validity of your DKIM record here.
     

16. In the TTL field for all the records (if editable) select the shortest possible time for the changes to take effect as early as possible.

After adding all three records, return to your Zoho Mail domain setup page and click Verify All Records. It may take about an hour or two for you to receive emails upon successful verification of your MX records and 4 to 48 hours for the propagation of SPF and DKIM records. You can look up all of these records' status in the DNS lookup tool.
