ConvertBox — on-site conversion optimization platform for targeted pop-ups, forms, and CTAs.
ConvertBox is a sophisticated on-site messaging tool that lets marketers deploy pop-ups, slide-ins, sticky bars, embeds, and full-page takeovers with deep behavioral targeting. The DB lists pricing as $49/month — this is incorrect; ConvertBox is primarily sold as a lifetime deal ($495 one-time for Standard, $590 for Pro), with a subscription option around $99/month. It's a mature tool trusted by thousands of marketers and agencies for conversion-rate optimization.
ConvertBox punches above its weight: the targeting logic rivals enterprise tools, A/B testing is built in, and the one-time lifetime deal makes the ROI math easy for anyone doing serious list-building or e-commerce conversion work.
No free trial — only a 30-day money-back guarantee. Lifetime deal pricing may increase or close at any time, and the subscription rate (~$99/mo) is steep if you miss the one-time window.
