Why customers love Privy
Having a Customer Success Manager has been key. They know conversion, email, and popups inside and out. Privy has saved my store during tough times — I’m a customer for life.

Amazing experience! Support were so helpful, and really kind, given I was responsible for the issue! So impressed at how quickly my issue was resolved, and the communication was top notch!
The Three Little Floofs
"I cannot say enough great things about Privy associate, Jessica L. She went Above and beyond to walk me through the steps of setting up the pop up, making sure the discount codes were synced with Privy, and even assisting with migrating my contacts from MailChimp to Privy. She is awesome! Privy is my favorite app!"
The Royal Bloke
"The fact that we have a dedicated CSM at Privy is amazing. In the 10 years that we were with Mailchimp, I think I spoke to a living person once. Just once."
Barrister and Mann
Privy’s customer service is unmatched. Our inquiries are always met with so much help and offers to hop on a call. We moved everything over and never looked back!
Truly Lifestyle Brand
I have been very pleased with the Privy service over the last couple of years. But I especially LOVE my CSM (customer success manager). He is so helpful and is always my cheerleader.
