Leanplum's user guides and developer documentation.

Leanplum Documentation

Leanplum's user guides, SDK setup, API docs, and more resources are here to help you get the most out of A/B testing, Campaigns, Messaging, and Analytics.

The audience for a new campaign is set to “All Users” by default. You can narrow the audience by including or excluding an audience. Also, by defining additional rules from the Advanced Mode.

Include and/or Exclude Audience

You can include or exclude users from the audiences available on your Audiences page.

Advanced Mode

The Advanced mode helps you make quick customizations while giving you insights about the best channels to engage your users on.

Holdback and Sticky Audience

This represents the percentage of users in your audience who are held out of the campaign.


Holdbacks allow you to measure how effective your campaign is by comparing users who received the campaign to users who were held back.

Sticky Audience
By default, users who stop qualifying for the campaign won't receive any further actions. Your campaign audience is re-evaluated before every action is sent.
By making your campaign audience sticky, you force users to keep receiving actions.


The Insights section helps you understand the audience targeted better. You can see the total number of users that will receive the campaign, how many can receive emails or push notifications, and how many have been active in the last 7 days.
