Use the serial or Oxford comma. That's the comma before the coordinating conjunction (and, or) in a list of three or more things. 

The Anaplan platform connects people, data, and plans.

 If a series contains more than three items or the items are long, consider a bulleted list to improve readability.

In a list of two things, no comma is necessary. 

Anaplan helps you track sales and forecast incentives at any level.

Don't use commas in calls to action or buttons.
