How do I solve my Sender Policy Framework (SPF) issue with Zoho Mail?

Technical Q&A

Topic summary

Main issue: Emails sent from a Zoho Mail–hosted domain now show a Gmail warning that the sender cannot be verified.

Context: The domain’s DNS is managed by Google. Zoho prompted the user to set up Sender Policy Framework (SPF) and to add specific DNS records in the Google DNS console.

What SPF is: A DNS TXT record that lists authorized mail servers for a domain, helping recipients (like Gmail) verify that messages are legitimately sent from that domain.

User need: The original poster does not know how to add the SPF record in Google-managed DNS and asks for step-by-step help.

Follow-up: Another participant asks whether the issue was resolved.

Status/outcome: No instructions or solution provided in the thread. The discussion remains open; key next step is adding the Zoho-recommended SPF TXT record in Google DNS per Zoho’s guidance.

Hello, I have used zoho mail to be my email hosting provider for a few years. Recently, all my emails using the domain name send to others show that “Gmail was unable to determine whether this email was sent from my domain. Do not click on links, download attachments, or mention personal data in replies.”

Then I notice zoho asks me to do Sender Policy Framework (SPF). It said that “We have identified that your domain manager is ‘Google’. Login to your ‘Google’ DNS account.” and “Now, add the below records into the DNS settings page. Click here for detailed instructions.”

But I totally do not know how to do it, could anyone please help me? Thank you.
