Nearly 15% of all online shoppers are repeat customers.

While they’re a relatively small percentage overall, returning customers actually make up about 1/3 of all online shopping revenue, and they spend 3x more than one-time shoppers on average.

Not only that, it also costs less to bring back a previous customer than to acquire a new one. So, focusing efforts on customer retention strategies — whether by community building with UGC, or optimizing lifecycle emails —  is key to eCommerce success.
