What Claspo is

Claspo is a web-based popup builder for businesses that want to collect opt-ins and encourage sales from existing website visitors. It offers pop-ups, floating boxes and bars, embedded and fullscreen widgets, and click-triggered teasers. Campaigns can target visitors by signals such as exit intent, time, scroll depth, pages viewed, device, geography, traffic source, URL, events, cookies, and custom variables. The editor includes more than 1,000 mobile-responsive templates that can be customized with drag-and-drop controls and no code. For interactive campaigns, widget formats include a spin the wheel, slot machine, memory cards, treasure hunt, scratch card, and pick a gift. Claspo says its AI agent can analyze traffic and visitor behavior, create campaigns, run A/B tests, and keep optimizing them. Integrations include marketing services, CRM platforms, website builders, and ecommerce platforms such as HubSpot, Mailchimp, Salesforce, WordPress, Wix, WooCommerce, and Shopify. Google Tag Manager can embed widgets on sites regardless of CMS, and webhooks support custom connections. The Free plan costs nothing and has no time limit. It covers one website and includes unlimited widgets and team members, with a “Powered by Claspo” badge. Eligible accounts can activate a 14-day Pro trial after reaching the Free plan pageview limit.
