Pressure management

Pressure management gives you the tools you need to avoid overwhelming users with push notifications while still re-engaging them efficiently. Keep in mind that users can disable push notifications altogether for your website / app. Using pressure management will avoid this and help you keep your subscribers.

Pressure settings allow you to define:

  • Frequency capping, that's the maximum number of messages per hour, day, or week that a device will receive from a given app or website.
  • TTL (Time To Live), the maximum amount of time that push gateways (Apple, Google...) try to deliver the notification.

Setting up pressure management

Pressure management is set up in the Settings of your project, under the Pressure tab.

Subscriber Protection

Subscriber Protection gives you control over how frequently users receive your push notifications by letting you setup a global capping for each user. Whenever that limit is reached for a particular user, subsequent notifications will be dropped for that user until the limit is reached again, in the other direction.

To setup Subscriber Protection, activate the checkbox, choose a maximum number of pushes and a period of time.

You have the option to disable Subscriber Protection for API calls if you so wish. If unchecked, API calls will be subject to your Subscriber Protection setting just like any other notification.


We strongly encourage you to setup Subscriber Protection and enjoy it's long-term benefits, including higher click-through rates, a fast-growing subscriber base leading to more clicks.

Keep in mind that using our Content Delivery Network to display images in notifications is only available when Subscriber Protection is active. When it's not, you'll have to use your own CDN to display images in your notifications.

Time-to-live (TTL)

The TTL is the amount of time for which push gateways try to deliver the notification. After the TTL, the notification is dropped.

Reasons why a notification is not delivered are usually related to devices being offline or turned off.

By default, the TTL is 72 hours. If your notification contains time-sensitive information, you can use a lower TTL to avoid sending obsolete information to the user.

Pressure categories

Both Subscriber Protection and TTL settings can be customized by pressure category. This allows you to use different settings for different types of push notification content.

There are 5 pressure categories:

  • Marketing
  • News
  • Transactional
  • Discount
  • Announcement

They come preset with different frequency capping and TTL settings which you can modify to adapt to your business needs.

When composing a notification in the notification editor, you can choose the pressure category of the notification in the pressure settings section:

You can also disable Subscriber Protection altogether for a particular notification by choosing the appropriate entry in the pressure settings:
