Our experience working with Cluster is great, the personal onboarding was awesome and I´m confident that the new popup will convert a lot more than our old one.

The direct communication with the founders is a bonus, because usually if you have an issue, other apps send you, either to a bot or a customer service agent.

Results speak for themselves. My stores opt-in rate went from a 1.2% to an ~8% opt-in rate.

It gave my store the ability to hone in on what is working, iterate, and adapt. Really can't recommend ...

Its been a pleasure working with the Cluster team, who will work with you on strategy and implementation of the popup, and cares about the lift they ...

Cluster's pop-up really helped to excel our opt-in rates. Since I started using Cluster, it ramped up 4x more than before. We had a Klaviyo popup to get emails, but were only seeing ~2% opt-in rate. After installing Cluster, we saw a 4x increase immediately! Proof that small tweaks can drive major impact.

The founders are also extremely responsive and helped us A/B test changes to the popup to ...
