🎡 Gamified popups that convert 3x

Visitors ignore plain popups. A game gives them a reason to interact. In our benchmarks, built on thousands of live widgets across industries, gamified popups convert on average 3x better than standard ones, and the top quarter of campaigns reach a 26% opt-in rate.

• Spin the Wheel: a prize wheel in exchange for an email
• Scratch Card: made for mobile, scratch to reveal the prize
• Gift Box: pick a box, open a reward
• Seasonal mechanics: Break the Egg, Shake the Christmas Tree and more

You decide the rewards, the chance of each one and how often it comes up. For example: 50% for 5% off, 25% for 10% off, 15% for 15% off and 10% for free shipping.

🧩 Every popup type you need

• Lightbox popup: a window over the page for offers, announcements and forms
• Floating box: stays in the corner while the visitor scrolls
• Floating bar: a bar at the top or bottom of the screen
• Built-in widget: a form embedded in the page content
• Launcher: an icon or button that opens the popup on click
• Content locker: unlocks content after a form is filled in

There is a template for every job: newsletter signup, welcome offer, exit intent, lead magnet, lead collection, preorders, callback request, age verification, exit-intent survey, notifications, video popup and many more.

🎯 The right popup for the right visitor

Set placement and display conditions without a developer:

• Audience: new or returning visitors, device, country, region and city
• Behavior: time on site or page, scroll depth, inactivity, exit intent, number of pageviews
• Context: page URL, traffic source, UTM parameters, cart activity
• Your own data: cookies, local storage, Data Layer values and JavaScript variables

With UTM targeting, a visitor from a specific email, social or paid campaign sees the popup made for that campaign, so discounts go to the moments that close a sale rather than to everyone.

WordPress targeting out of the box. The plugin hands Claspo what WordPress knows about the page and the visitor: the kind of page, its categories and tags, the WooCommerce product with its price and stock, the cart total, items and coupons, and whether the visitor is signed in. Use any of them as a display condition. Every group can be switched off on the plugin’s Targeting data tab.

🧠 Qualify before you collect

An email is easy to get. Knowing who you are adding to the list is worth more. Ask a question or offer a choice before the contact form: a multi-step flow lowers friction and tells you what the visitor is interested in, how ready they are to buy and which incentive works. A teaser lets them reopen the offer after closing it.

🤫 Popups that do not annoy

• Silence interval: a gap between popups, 3 minutes by default, adjustable
• Overlap protection: two widgets never show at the same time, even with duplicated rules
• Frequency rules: how often a returning visitor sees the same campaign

🧪 A/B testing on autopilot

Compare offers, audiences, messages, triggers, layouts or game mechanics, not just button colors. Autopilot shifts traffic to the variant that performs better and keeps the test running. Analytics show views, conversions, target actions, device data, reward statistics and confidence scores, so you know which version is ahead and how sure the result is.

✨ Conversion components

• Dynamic text roller: rotate several offers in one line, handy for Black Friday and other short events
• Slider: several images or videos in one popup
• Multi-step form: basics first, preferences later
• Countdown timer: starts for each visitor individually
• Promo codes: shown right after conversion, no email round trip
• Exit-intent survey: ask leaving visitors why

🎨 Templates and the editor

Start from one of 1,000+ CRO-ready templates or from a blank canvas. Change copy, buttons, colors, fonts, logos, images and video; add fields, components and steps. Every design is responsive, with separate desktop and mobile views. Multilingual content with AI auto-translate, right-to-left languages and accessibility-friendly designs are included.

🔌 Works with your tools

New contacts go straight to your marketing stack, together with the data from the popup: Mailchimp, MailerLite, HubSpot, Salesforce, Klaviyo, GetResponse, SendGrid and many more, plus Zapier and webhooks for anything custom.

Claspo works with WooCommerce and any theme, and alongside caching plugins such as WP Rocket, WP Fastest Cache, LiteSpeed Cache, Autoptimize and Hummingbird. The script loads asynchronously, so pages never wait for it.

🛠️ What the plugin does in WordPress

• One-step connect: paste your Script ID, or sign up and the site connects itself
• Status where you work: a dashboard widget, an entry in the toolbar on your site, and a notice if popups stop showing because the pageview limit is reached or nothing is published
• Your widgets at a glance: which are live, which are drafts, which are in an A/B test, with a link to each widget’s leads
• Targeting data: WordPress and WooCommerce values for display conditions, with a reference table of every variable
• Cache aware: clears popular caching plugins when the script or the settings change

After 14 days, the selected plan continues as a paid subscription with a 30-day billing cycle.

How are pageviews calculated?

A pageview is counted each time a page with the Claspo script loads.

If a visitor refreshes or revisits the page, it counts again.

We use pageviews, not impressions, because triggers are evaluated on every visit:

• time delays;
• scroll depth;
• exit intent;
• cart behavior.

Even if no popup is shown, the system processes the visit to decide whether it should appear.

Can I integrate Claspo with my email or CRM platform?

Yes. Claspo integrates directly with popular tools:

• Mailchimp
• MailerLite
• HubSpot
• Salesforce
• Klaviyo
• GetResponse
• SendGrid

You can also use webhooks or Zapier for custom integrations.

Does Claspo work with WooCommerce?

Yes. Claspo works alongside WooCommerce and is declared compatible with High-Performance Order Storage. You can target campaigns by cart activity and shopping context without changing the rest of your setup.

Will Claspo conflict with other plugins or affect site performance?

No.

• Loads asynchronously, so it does not block page rendering;
• Triggers evaluate in about 200ms;
• Compatible with modern WordPress versions;
• Works alongside other plugins, including caching plugins such as WP Rocket, WP Fastest Cache, LiteSpeed Cache, Autoptimize, and Hummingbird.

Can I cancel my subscription?

Yes. You can cancel at any time from your account settings.

How does Claspo handle user data?

This plugin uses the Claspo service to enable features such as popups for email capture, lead generation, notifications, and surveys. Claspo provides the platform for creating and managing these web widgets.

To understand how Claspo handles user data collected on your website, please refer to our Data Processing Agreement, Terms of Use, and Privacy Policy.

What does the plugin itself send to Claspo?

Two things, and both are listed here so there are no surprises.

• To show the status of your widgets in wp-admin, the plugin asks script.claspo.io for the public configuration of your Script ID: once a day, when you open the plugin page or the dashboard, and when you click Check now. The request carries only the Script ID. No content, users or visitor data from your site are sent.
• With a targeting group switched on under Targeting data, the plugin hands the matching values to the Claspo script in the visitor’s browser, so you can use them in display conditions: the kind of page and its categories, the name and price of the WooCommerce product being viewed, the cart total and item count, and whether the visitor is signed in. Product and cart groups appear only on sites with WooCommerce. Cart and sign-in values are fetched per visitor and never written into a cached page. Every group can be switched off.
