As far as abandoned carts are concerned, it is a constant problem with any e-commerce site. In fact, about 50-80% people adding something to the cart abandon the purchase according to industry standards. What are the numbers you are seeing?
In general though, it is helpful to think about this problem from the point of view of the customer and their stage in the purchase journey.
Why are they abandoning the purchase? If they have added something to the cart, we can assume they did find something they were looking for. So the reasons for abandoning now could be:-
To recover these abandoned carts, it becomes important to engage with these people who are abandoning the website. This retargeting can happen through multiple channels - Facebook Ads, Google Ads, Email, SMS, Messenger. Ideally, you should optimize for channels which allow you to get into a conversation with the customer if you have not yet nailed why are customers abandoning your website.
I am actually building out something to solve this problem (check my website) and I'll be happy to help you :).
