Introduction to Zoho ZeptoMail

Zoho ZeptoMail is a transactional email service designed to deliver time-sensitive emails triggered by user actions—such as OTPs, order confirmations, or password resets. It is built exclusively for automated transactional emails ensuring faster delivery, higher inbox placement and reliable security. ZeptoMail doesn't recommend sending marketing emails using the service to maintain maximum deliverability and sender reputation.

Transactional emails

Transactional emails are automated emails usually triggered by a user action on a website or an application. The recipient is actively seeking these emails. They consist of sensitive information based on user behaviour on a website or an app. Non-delivery of transactional emails can impact your customers and your business. Examples of transactional emails are :

• Account Creation - User invites, account activation emails, password reset emails, log-in attempt notifications.
• Billing Information - Information about credit card payments, addition and deletion of beneficiaries, sending OTPs or information related to electronic fund transfers.
• Payroll systems - Payslip and salary information.
• Payments - Purchase receipts, refund emails, confirmation messages, cancellation messages, payment subscription emails, abandoned cart emails, invoices, payment failure or subscription renewal emails.
• Notifications - Trial expiration emails, account-reactivation emails, account deactivation emails, privacy policy updates, new sign-in messages, account deletion messages or other account-related notifications.

Marketing emails

Marketing emails are usually a single message (like newsletters, promotional emails etc.,) sent to a large group at once. They are not triggered by a particular user action on a website or application, but are scheduled by marketers. Hence, users are not actively seeking these emails.

Transactional emails differ from marketing emails in the following ways :

Why are marketing emails not allowed in ZeptoMail?

We support transactional emails alone to ensure greater deliverability and to maintain trustworthy IP addresses. This is done owing to the fact that marketing emails have a higher possibility of getting flagged as spam. As a result, internet service providers might deem the IP addresses unreliable. Having a common IP for both marketing and transactional emails will affect your transactional email delivery. Hence we have separated both to ensure maximum deliverability for your transactional emails.
