Studies show that about 75% of shoppers who abandon their carts usually plan to come back. By adding an Abandoned Cart email you can send a friendly reminder to shoppers, encouraging them to buy today and pay for it later with Klarna. Make sure to include a call to action encouraging customers to 'Shop Now'.
Give an incentive to shoppers who return to their shopping carts. Offer a discount code, free shipping, or next day delivery in order to boost conversion.
According to the European Commission's definition of legal grounds for processing data you're compliant as long as you have explicit consent from the visitor to receive those emails.
