This one helps you build popups and modals that actually convert without pissing people off. It covers the whole spectrum: email capture, exit intent, lead magnets, announcement banners, slide-ins. The meat is in the trigger strategies (scroll depth, time-based, behavior-based) and copy formulas that skip the manipulative dark patterns. You get specific guidance on frequency capping, mobile considerations, and GDPR compliance. The benchmark numbers are useful (2-5% for email popups, 3-10% for exit intent). If you're doing any kind of lead gen or ecommerce, this walks you through the entire decision tree from trigger to copy to A/B testing without the usual growth hacker nonsense.
