Personally, I find it works excellent, I sure recommend it if you are looking for an alternative to the much more expensive app like klavyo

— Grondsync

This app looks like a great tool for creating forms and popups. The team behind it has been incredibly helpful, and their support has been top-notch!

— DTF ULTRA

Great app I would definitely recommend if you are looking to grow your customer base. Great support if you have any questions as well.

— Ferla Family - Cargo Bikes

Thanks to this application, I can collect extremely useful customer data in my store with the forms I have created and will create. It is truly legendary.

— Azulline ES

This app is perfect for managing emails! We've been searching for an easy app to handle our pop-ups on the store, but most options have either been too expensive or difficult to manage. This app is incredibly user-friendly, with a dashboard that's easy to navigate. I recommend it to anyone looking to increase their email flow. Give it a try!

Great App, Amazing team support. Yusuf always make a great work!

— Apluf

A promising app for creating forms and improving opt-in rates. We're just trying out the app and will update the review with results. We've also been a long time user of Assortion from the same team at Scooch Case and very happy with the team and support.

— Scooch

Awesome tech support with fast responses. Looking forward to the A/B testing feature!

— Lumos Sleep

First impression looks really good, I'm excited for the A/B testing results with it! The support team is awesome, always there to help if anything is needed.

— DeinPhysio24

Looks good, very intuitive and easy to use. I need to increase my AOV and recover clients and this app seems ideal for that. Like in other app of the same company, the customer support is a 10/10.
