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.

   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.
   • Ensure that you have deleted all the MX records related to your previous email provider. Any other existing MX record will conflict with Zoho Mail, affect email delivery, and result in permanent loss of emails delivered. Learn more.
   • The MX records that should be returned when you check in the MX Lookup tool should be 
     • mx.zoho.com
     • mx2.zoho.com 
     • mx3.zoho.com
       ​
9. To add the SPF records, Click ADD record and select TXT from the Type drop-down list.
10. Specify the Name/ Host as "@".

11. 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.
       
12. 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.
13. 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.

14. 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.
       
15. 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.
