In the last 30 days, my store's email opt-in rate increased from 1% to 13.4%. The Cluster popup, after iterating with the Cluster founders and finding a deal that resonated with our customers (a free gift), led to a popup conversion rate of 23%.

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 generate *specifically* for your store.

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.

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 further dial in the performance after launching v1 of the popup.Highly recommend.
