Email should drive 20 to 30% of eCommerce revenue. Most stores capture a fraction of that.
You Are Paying To Acquire Customers You Never Email Again.
Most eCommerce brands pour budget into paid acquisition, then let the customer database sit idle after the first purchase. Email and automation recover that spent-for revenue by bringing existing customers back to buy again, without adding a cent to ad spend.
