The use of predefined rules to trigger email messages based on specific actions customers take—or don’t take. Some examples include a welcome email that sends when a customer signs up for a mailing list, or a quick reminder that the customer placed something in their cart but never finished checking out. Email automation takes repetitive tasks off your to-do list to free up your time for other valuable tasks, such as responding to customer questions. It can help customers learn more about your brand, encourage them to keep coming back, or remind them of why they bought from you in the first place.
