Good communication is a foundation stone in any online business, by keeping in touch with your customers you promote trust and brand recongnition for being professional. When emails go ignored and requests go unanswered this reflects poorly on you and your business. Usercart X Standard has two emails systems, the first is automated and is attached to the orders so that order statuses are sent to the customer automatically. The second is the emailer which allows you to email specific or all customers from within the Admin Dashboard. You can send emails using the built in HTML Editor. Preview the contents and then just click send.
A handy tool to have directly in your shop, this will save your time and trouble.
