The best pop-up & lead capture apps in 2026
Signup pop-ups, spin-to-win wheels, exit intent, giveaways: the apps building the email and SMS list, ranked by auction.
How this leaderboard works
Every position is an auction: pop-up apps bid real money, starting at €5, and the highest bid takes first place. No jury, no sponsored reviews — the leaderboard moves the second someone bids more. Clicks sent to each site are counted and public. The full rules.
How to choose your lead capture app
Judge a pop-up on its conversion rate AND what it costs in experience: the winning duo remains a clear offer (welcome discount, early access) triggered at the right moment — after a few seconds of engagement or on exit intent, never on landing. Healthy signup rates run 3 to 8%; beyond that, check the quality of the list you're building.
The app must sync cleanly with your email/SMS platform (consent field, source, segments), respect Google's mobile rules (aggressive interstitials penalise mobile SEO), and allow targeting — new visitors only, per page, per traffic source. Spin-to-win converts hard but also attracts code hunters: test on YOUR audience.
What to compare
Compare: triggers (delay, scroll, exit intent, per page), targeting (new/known, source, device), Google mobile compliance, sync with your email/SMS platform, offer A/B testing, and per-view pricing. The average conversion rate observed per template is the number to ask for.
Frequently asked questions
What conversion rate should a pop-up achieve?
Between 3 and 8% of visitors for a clear, well-triggered offer; gamified mechanics (wheel, game) go higher but with a lower-quality list. Below 2%, change the offer or the trigger before changing the app.
Do pop-ups hurt SEO?
On mobile, intrusive interstitials on landing from Google can cost you: the rule is not to cover the content on arrival. A delayed pop-up, exit intent, or a discreet banner remain safe — good apps have dedicated mobile settings.
Welcome discount: how much to offer?
10% is the standard that converts without eroding margin too much; a fixed amount ("€5 from €40") protects small baskets better. The no-discount alternative — early access, content, a game — preserves margin but converts less: decide on your LTV.
