True or False: Common uses for active lists include sending emails based on each contact's behavior.

Active lists in HubSpot are designed to dynamically update based on the criteria set by the user, such as contact behavior. This means that if certain conditions are met, like a contact opening an email or visiting a specific webpage, they can automatically be added to or removed from an active list. This functionality allows marketers to tailor their email campaigns according to individual behaviors, ensuring that the right messages are sent to the right people at the right time.

For example, if you have an active list set up for contacts who have engaged with a specific piece of content on your website, you can easily send a follow-up email to just those individuals. This targeted approach increases the likelihood of engagement and conversion because the messaging is personalized and relevant to the contacts' recent activities.

While static lists do not change once created, active lists provide the flexibility necessary to respond to real-time data, making them a powerful tool for email marketing based on contact behavior. Thus, the statement regarding the common uses for active lists being related to sending emails based on behavior is indeed true.
