DKIM is a security mechanism that validates an email, checking if emails were sent from a valid source and not tampered with during transit. DKIM ensures that emails will be delivered to the inbox of its intended recipient since the validity of the email has already been verified.
Once you complete the DKIM configuration and get your domain verified, you can use it to send emails from Zoho Forms.
