How to capture emails on your website/store and utilize pop-ups to the maximum.
1. Site-wide website opt-in → simple opt-in in exchange for a discount, unlock extra content, free guides, etc.
Now don't be boring with the usual 'enter email to receive updates' because no one puts their email in there.
Give an incentive.
2. Exit intent → give a discount when they try to leave the website (when their mouse moves towards the top of the desktop, a pop up appears)
