This traditional form of email marketing can be an asset to roundup announcements to your email list that tell them more about your eCommerce business, any upcoming events and sales. While it is still a good use of email marketing, customers nowadays are bombarded with information overload, newsletters included.
As a solution, try organizing relevant information together while keeping the other stuff separate. What this allows you to do is to send shorter, compelling emails that are straight to the point without overwhelming the reader with too much data.
