True or False? You can only use one type of smart rule per module.

The statement is true because, in HubSpot's CMS, smart rules enable content personalization based on user characteristics or behaviors. Each module can utilize only one type of smart rule at a time, meaning that if you create a smart rule to customize content for first-time visitors, you cannot simultaneously apply another smart rule of a different type within that same module. This restriction ensures the effectiveness and clarity of the rules in the context of personalization, avoiding conflicts or confusion over which audience segment a particular piece of content is targeting. Thus, it reinforces the principle of streamlined user experience and targeted marketing efforts within campaigns.
