Email Automation is a system which uses some software and tools to send Emails automatically following various schedules and pre-defined triggers. Multiple automated emails are arranged in a sequence to create user funnels and segments on the basis of user behaviors. Let’s consider an example. An automation funnel is set in such a way so that “Email A” will be sent to a person if he shares his Email Id. However, either “Email 2a” or “Email 2b” will be sent surely and in that case, the person may click the first Email or may not.
