Hi.It is possible to make a pop up appear, offering a discount code on an abandoned cart? And it is possible to have it different depending on cart content? (i.e. 5% for a brand/collection, 8% for another one?).
Yes, please take a look at the APP store. There are plenty of apps for abandoned carts.
let me know if this helps you, if yes please accept my answer and give thumbs up! thanks
