Case Study: Boomerang achieves 140% conversion increase and 52% lower CPA with Taboola

Boomerang Reaches Audiences on Top Sites Around the Web, Powering User Acquisition

Boomerang for Gmail is a browser extension that helps users schedule emails, snooze messages, set reminders, and track reads to improve inbox productivity. The company relied heavily on paid and organic search for user acquisition, but faced low conversion rates and a high cost-per-acquisition, so it partnered with Taboola to add a “discovery” channel and reach new audiences across top publisher sites.

Together they ran rigorous A/B tests to redesign landing pages for discovery traffic—adding story-driven content, engaging visuals, and a more effectively placed “Install Now” CTA—hosted on testing sites to iterate quickly. The campaign generated over 3,500 leads during the trial, lifted conversion rates by 140%, cut cost-per-action by 52% (bringing CPA below target), and convinced Boomerang to double its investment in Taboola.
