Power Up Email Marketing with Claspo Widgets

Email remains the #1 direct channel, and websites are the #1 channel for engaging with a brand. Add Claspo's widget to your site, and you'll have a steady source of leads and revenue growth.

Use Relative Countdown Timers

Increase signups with FOMO! Add a relative countdown timer that activates when a visitor first sees a pop-up. If time runs out before the user converts, the timer will disappear. But the offer will still be available to other prospects. A pop-up with a tempting offer and a timer has a 112% higher CR than a regular one.

Inspire with Video Widgets

Catch your website visitors' attention with video widgets. Show new cool products or features and offer email sign-ups for discounts. Leads may turn into buyers quickly, as nearly 91% of consumers say videos inspire them to make a purchase.

Highlight a Few Offers with Slider

Showcase multiple deals or products in one pop-up. Claspo's sliders let visitors browse the offers to find the most attractive ones, increasing engagement and conversions. Add as many images or videos as you want.

Benefit from Promocodes

Add a promo code to a widget and target its display to new site visitors, or offer a nice discount in an exit-intent popup. 4 out of 5 consumers are encouraged to make their first purchase from a new company when they see an offer with a discount code. Let visitors complete their purchases, then offer them to subscribe to your newsletter.

A/B Test Widgets for Growth

Test different widget designs, messages, placements, and display conditions. Track results to find your conversion champion. Through A/B testing on our blog, we saw a 300% increase in newsletter signups. Imagine what you could achieve!

Go Global with Multilingual Pop-ups

Create pop-ups in multiple languages to engage with visitors better. Claspo automatically displays content based on their browser settings or website language selection.

Set Up Triggers for Targeted Pop-ups

Target your audience for maximum impact. Our trigger rules let you:

Reach local customers with geo-targeted promotions

Welcome new visitors with special offers

Personalize pop-ups based on email’s UTM

Enjoy Clean and Fast Widgets

Widgets done right: Claspo ensures a clean UX with:

Silent interval: no more overwhelming visitors with simultaneous pop-ups
