I started out using Privy for my pop-up to capture leads in multiple ways. Then decided to use them for email marketing. We set up automations, cart abadonement campaigns and weekly email campaigns.They have great customer service and sales support to assist in building out automations, if you want or need the help. I would highly recommend Privy!
The open-ended nature of the platform lets us customize our on-site displays not only to drive conversion but to alert customers to changes, closures, and anything we need to communicate.
