Email Deliverability | Email Notifications - Zoho Forms

Hello, form builders!

We would like to inform you about some changes we're making in Zoho Forms to ensure the deliverability of your outbound emails.

Changes to Gmail policies

Gmail has updated its DMARC policy which quarantines emails sent with or in the sender (From) address. The recipient's email service may flag such emails as spam or junk. Such quarantined emails may not be visible in the customer's inbox, spam, or junk folders.

Review Gmail's full email sender guidelines.


What is DMARC?

DMARC (domain-based message authentication, reporting, and conforming) is a security measure to protect against phishing attacks in emails. It sets a standard for how email systems verify the authenticity of messages and gives senders feedback. Following the recommended DMARC policy helps maintain a positive reputation for the sender's domain and adds an extra layer of protection against malicious emails. Learn more about DMARC.

If the email domain used for sending email notifications to form respondents (who use Gmail) is not aligned with DKIM or SPF requirements, then Gmail will treat your emails as spam.

Gmail requires the DMARC record to be published for domains which send more than 5,000 emails per day to or email addresses.

Actions required

  • DKIM is now enabled in Zoho Forms' Free plan. Users with their own domains are required to configure DKIM to prevent their emails from being flagged as spam. Learn about DKIM configuration in Zoho Forms.

  • Please refrain from using or in the From address in your notification settings. Use your own domain with DKIM authentication.

  • Zoho Forms will allow users to continue using From addresses with the domain until January 31, 2024.

  • If you are using your own domain, kindly add a DMARC record and configure DKIM in Zoho Forms. Learn about adding a DMARC record.


From February 01, 2024, email notifications from your Zoho Forms account being sent using or email addresses will be sent using Zoho Forms' default email address corresponding to the data center of your account:


Data Center

Zoho Forms' Default Email Address










Going forward, Zoho Forms will apply the same policies to all public domains such as and to ensure consistent email deliverability for our users.
