OptinMonster provides a lot of customization options. One of its most powerful features is its Exit Intent technology. It detects when a user is about to leave your website and will cause a popup to appear just before they would leave. Aside from exit-intent, OptinMonster also has trigger options based on time on page, location on the website, manual clicks on images and links, as well as referrer source such as search engine, social, favorite website, etc.
