We've had a great experience using Privy to grow our email list and improve customer engagement. The pop-up builder is easy to use, and setting up campaigns like welcome discounts, exit intent offers, and abandoned cart recovery was surprisingly straightforward. We also appreciate having email, SMS, and popups in one p
I originally signed up for a monthly plan of $15 to create a pop-up. Without knowing, I have been charged $45 monthly for my users which don't have anything to do with the use of the app. This is absolutely absurd.
Excelente servicio.
Super available and ready to help with expertise..AND... it's a real person on the other end! The best.
Responsive & friendly customer support! Jose was fantastic and got me the answers I needed quickly.
