What Our Clients Say About Us

Yuliia Y.

eCommerce Specialist

Pros: Convenience and ease of use, wide customization, good support, excellent form analytics. We used a floating bar, pop-up informer and regular forms to collect phones. All forms showed excellent results! Cons: I wouldn't call it a minus. For our needs, Claspo has everything and more.

Our conversion rate increased by 3.9 times thanks to the SPA supported by Сlaspo. The script works more correctly, is more stable, and loads better. We really enjoy multilanguage widgets and geotargeting!

Viktoriia Tsalpinska

Email marketing specialist, Grade.ua

We decided to introduce a floating information widget. It is not intrusive, but it had to appear with each new session. Claspo was the easiest way to do this. The platform is easy to understand, you can figure everything out in half an hour.

I like the flexibility of Claspo. With the help of the drag&drop editor, I could adjust the colour and add the font. It was also quick and easy to customize the location and functionality of the widget. These features really save time and allow you to get the widget you wanted.

The product is easy to use. I have many clients and we've integrated Claspo over 10 times. It is convenient that there are stylish templates and you can always be in time for the holidays to run an interesting promotion, promo code for the first purchase, or a big sale. I advise everyone to try it.
