FAQ
Your frequently asked questions, answered.
Still curious about how we work, what we deliver, or whether retention is right for your casino? We’ve answered the most common questions below.

We work with all major ESPs and CRM systems—Customer.io, Klaviyo, Optimove, etc. We’re also official partners with several top providers.
We bring 8+ years of focused experience, benchmark insights across 15+ brands, faster execution, and a fully equipped team ready to go.
