Message throttling

You can add message throttling from the Keys & Settings window in App Settings. This allows you to limit the number/pace of messages sent, which can help distribute any increased load on your servers over a longer period of time.

Leanplum throttles based on messages per minute: "Send up to N messages per minute per campaign." This gives you precise control regardless of the number of users in the targeted audience.

🚧

Throttling only applies to one-time/recurring scheduled campaigns sent to more than 50 users.

Be sure to set a reasonable limit given the size of your userbase. Any messages not sent after 30 days (due to throttling) will be dropped.

To add a throttle, once in the App Settings page:

1. Find the app you wish to throttle message delivery for and click on the Keys & Settings link (Note: This requires your account to have Admin or Member privileges for that team).
2. Click on the Messaging tab.
3. Go to the Throttling section.
4. Enter the maximum number of messages you would like to be sent per minute for any given campaign.
5. Click Done.
