   The MX values given here are based on the generic configuration information. For more specific configuration particular for your domain refer to this section in the Admin Control Panel.

7. Choose TTL to the minimum value available. It should be 4 Hours in the case of Bluehost.
   
8. Once done, click Save. Similarly, enter the second and third MX Records.

You have now added the MX Records successfully. You may have to wait for at least 6 to 24 hours for the changes to take effect in the DNS Servers.

Important Points:

• 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. 
• 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
