What are the different types of popups and when should I use them?

There are several types of popups, each serving a different purpose. For instance, entry popups welcome visitors or highlight new offers. Exit-intent popups work best to capture abandoning users with discounts or reminders. Scroll-based popups appear after users scroll, ideal for promoting blog subscriptions. Timed popups engage users after a set time, perfect for lead capture. Use each type thoughtfully based on your audience's behavior.
