I highly recommend Optimonk as I've used it for several years and their newest 2.0 version is a great leap forward for ease of use and new features.
Excellent additional revenue generation, up to 1:20 ROAS. MUST HAVE for e-commerce store owners and agency owners who have clients with email marketing revenue generation vision.
The software, UX, UI, support, and price are all excellent, and this is the best in class solution for popups on Shopify. It drives great ROI at huge scale, and if you're not using it or something like it you're leaving money on the table.
It’s a misbelief that visitors hate popups. Visitors hate bad popups. Good ones, that create real value and customized user experience, are appreciated. That’s why I love OptiMonk. Thanks, guys
