About the subscription

A subscription for Kaspersky Secure Mail Gateway is a purchase order for the application with specific parameters (subscription expiration date, number of devices protected).

A subscription can be limited (for example, lasting one year) or unlimited (without an expiration date). To continue using Kaspersky Secure Mail Gateway after a limited subscription expires, you need to renew it. An unlimited subscription is extended automatically if prepayment is made on time.

When a limited subscription expires, you may be provided a grace period for renewal. During this grace period, the application remains fully functional.

To use Kaspersky Secure Mail Gateway based on a subscription, you must apply an activation code. After the activation code is applied, a key is installed. This key defines the license granting use of the application on subscription.
