ZeptoMail Subscriptions
ZeptoMail follows a pay-as-you-go pricing model instead of traditional monthly or yearly plans. This is done in the form of credits, where you pay only for what you use. Each credit allows you to send 10,000 emails and is valid for 6 months from the date of purchase.
The Subscription section of your ZeptoMail helps you keep track of the credit-related activity. This section contains details about credit validity, transaction details and purchase history.

Auto top-up
Auto top-up allows you to automatically purchase credits when your available balance drops below a specified limit. This ensures uninterrupted email sending without the need for manual purchases.
To enable Auto top-up, you must:
- Have a reviewed account
- Have purchased credits at least once
Steps to enable Auto top-up
- Navigate to the Subscription section from the left pane.
- Enable the Auto top-up toggle button in the top bar.

- In the auto top-up pop-up, configure the following:
- Minimum credits to be retained: Specify the minimum number of credits you want to maintain in your account. When your available credits reach this limit, Auto top-up will be triggered.
- Number of credits to be purchased: Select the number of credits to be automatically added. You can auto top-up a maximum of 2 credits.

- By default, Auto top-up is triggered one day before the minimum credit threshold is reached.
- Click Save.
Points to remember
- If your payment method is a credit card, the amount will be automatically debited during Auto top-up.
- For other payment methods, you will receive an email notification to complete the payment.
- You have 15 days from the date of credit addition to complete the payment. Failure to do so will result in a disruption of outgoing emails.
- If a previous Auto top-up payment is pending, the next Auto top-up will be blocked.
- Auto top-up can be enabled for a maximum of 2 credits. To increase this limit, contact support@zeptomail.com.
