There are several types of pop up alerts that can be used in email marketing:
Exit-Intent Pop Ups: These appear when a user is about to leave your website, offering them an incentive to stay or subscribe. Time-Triggered Pop Ups: These pop ups appear after a user has spent a certain amount of time on your site, indicating their interest and engagement. Scroll-Triggered Pop Ups: These are triggered when a user scrolls a certain percentage down the page, showing they are actively engaging with your content. Click-Activated Pop Ups: These appear when a user clicks on a specific element, such as a button or link, providing a more targeted approach.
