Answers to common questions about restock campaigns in XFlow.

<Expandable title="What is the difference between a campaign and a workflow?">

A **campaign** defines **which products are included** and **when notifications are allowed to run**.\
A **workflow** defines **the actions that occur after a restock**, such as sending emails or imposing delays.

> Campaign = *scope & control*\
> Workflow = *logic & actions*
