The sender email is the email id which recipients will see when they receive an email from you. Previously, Member Portal related emails could only be sent from the Zoho domain on our end. Now, you can associate additional email addresses to send Member Portal related emails.

Domain Authentication is a mechanism that verifies the email from the point of its origin by validating the email sender. It checks emails to rule out any possibility of spamming or spoofing thereby protecting the sender's good reputation. Authenticating your domain allows for smooth transfer of emails through spam filters and into your recipient's inbox.

Domain Keys Identified Mail (DKIM) is a security mechanism adopted for email marketing services to validate an email message. Its specific purpose is to:

1. Check if the email messages were sent from a valid source.
   
2. Check if the email messages were not tampered with in transit.

DKIM further ensures that email messages would get delivered to the inbox of its intended recipient because the validity of the email message has already been verified.
