Secure your domain from being misused by intruders by including in Zoho Mail a DMARC (Domain-based Message Authentication, Reporting & Conformance) policy. When establishing a DMARC policy, unauthenticated emails sent in the organization's name are either forcibly removed or denied, depending on the policy. Reports to make specific modifications to the policies may be produced for review.

Email Policy

Check your emails sent and received by customizing email policies in Zoho Mail for your company. Specific networks, devices, domains and users can be limited in order to prevent data leaks.

Malware Protection

Specific extensions are scanned and bounced back when a threat is found by emails received with a Zoho mail attachment. The Zoho Mail's protected attachment policy prevents the uploading of files with such extensions to prevent the transmission of malware.

Spam Filter

Zoho Mail would screen your inbox and permit secure and authenticated emails. The incoming emails are scanned for phishing and spoofing using the Spam filtering feature and pushed into the appropriate inbox or spam folder.

Encrypted E-Mail

Anybody other than the intended recipients can not read encrypted emails. By encrypting the data in storage and transit, the possibility of unauthorized interception is significantly reduced.

Encryption at Rest

E-mails are stored in encrypted format on Zoho Mail servers. Your data are divided into fragments and before being saved on our disks, every fragment is further encoded. The keys for encryption are handled extremely efficiently and securely.

End To End Encryption

Secure Socket Layer (SSL) authenticates email traffic with both your browser and the server. For all communication from POP / IMAP / SMTP clients to our servers, Zoho Mail uses SSL connection, so during the transition your data is unable to be read or manipulated.


Specific extensions are scanned and bounced back when a threat is found by emails received with a Zoho mail attachment. The Zoho Mail's protected attachment policy prevents the uploading of files with such extensions to prevent the transmission of malware.

 TLS Indicator And

Encrypted Indicator

The safety standard of emails you send and receive is also kept informed. All Zoho Mail server emails are encoded and marked as TLS in transit. If you do not support TLS by the other providers concerned, you will be notified by the email as Plain.

Secure  Access

The most important step to protect your data is to safeguard your account. In order to free you from phishing attacks, Zoho Mail has installed many protection lines.

Two Authentication Factor (TFA) furthers the account with an additional security layer. Touch ID, SMS and QR code are just a few of the different possibilities offered by Zoho Mail that can be used to prove the identity of your account when you sign in. You can always rely on TFA to keep your account secure even if your password is compromised.

Single Sign On
