EnglishWhat Is Claspo Popup Builder?
Updated
Claspo is a popup builder focused on conversion rate optimization (CRO). It lets you create popups from templates that are already designed to convert, then layer on AI-driven setup, targeting, and A/B testing. It's aimed at site owners who want to turn existing traffic into email opt-ins and sales rather than redesign their whole funnel. If you run a Shopify or WordPress store, or any site where you want more signups and fewer abandoned carts, Claspo is built for that job.
What Claspo actually does
The core idea is simple: instead of designing a popup from scratch and guessing what works, you start from a template with a known average conversion rate, then let the platform's automation improve it over time.
Claspo describes itself as a "pop-up builder that converts more," and its positioning rests on three things working together:
- CRO-ready templates — pre-built popups organized by use case, each with an average conversion rate attached.
- Agentic AI — an AI agent that analyzes your traffic, picks a tactic, builds and launches campaigns, and keeps optimizing them.
- Conversion boosters — A/B testing autopilot, 1:1 personalization, and high-intent triggering running in the background.
The template library and its conversion benchmarks
Claspo publishes average conversion rates (CR) for each template type, which is useful for choosing a starting point. These are averages, not guarantees — your results depend on your traffic, offer, and audience.
| Template | Avg. CR |
|---|---|
| Gamified discount | 9% |
| Countdown timer | 9% |
| Branching popup | 7.2% |
| Discount coupon popup | 6.2% |
| Exit-intent offer | 5.8% |
| Product discovery quiz | 5% |
| Newsletter sign-up | 4% |
| Cart abandonment | 4% |
| Welcome offer popup | 3.8% |
A practical read: gamified discounts and countdown timers sit at the top of the list, while newsletter sign-ups sit lower. That ordering is a reasonable guide for where to start if your goal is raw opt-in volume versus list growth.
How the AI agent works
Claspo's AI agent is trained on what the site describes as 1.6B+ pop-up impressions across 100K+ sites worldwide. According to Claspo, it:
- Analyzes your traffic and finds conversion gaps.
- Builds and launches campaigns using the best-fit tactic.
- Sets up A/B tests and identifies which version converts your traffic best.
- Learns from real visitor behavior and automatically promotes the top-performing version.
The stated goal is revenue-focused decisions — the agent prioritizes what's most likely to convert traffic into revenue. If you'd rather not manage tests manually, this is the feature that removes that work.
The three conversion boosters
These run behind the scenes without adding to your workload:
- A/B testing autopilot — automatic variant testing, performance monitoring, and winner promotion. Every popup improves itself.
- 1:1 personalization — dynamic content, traffic-source personalization, and onsite-action targeting, so each visitor sees the message most relevant to them.
- High-intent triggering — behavior-based triggers that show the popup when a visitor is ready to subscribe or buy.
Where you can use it
Claspo offers a Shopify app and a WordPress app, alongside a standalone popup builder. Ratings shown on the site are 4.9 on Shopify, 5.0 on WordPress, and 4.9 on G2. If you're on either platform, installation is a one-click app install; otherwise you use the builder directly.
Who it's for
Claspo fits if you:
- Already have traffic and want more opt-ins or sales from it.
- Prefer starting from proven templates over designing popups yourself.
- Want testing and optimization handled automatically rather than manually.
- Run a Shopify or WordPress site (or can add the builder to another site).
It's less relevant if you need a general-purpose design tool rather than a conversion-focused popup system, or if you have very little traffic — A/B testing and AI optimization need volume to learn from.
Getting started
- Sign up for free or install the Shopify/WordPress app.
- Pick a template matching your goal (discount, exit-intent, cart recovery, quiz, etc.).
- Let the AI agent or your own setup configure targeting and triggers.
- Launch and let A/B testing autopilot promote the winner.
