Creating a segment for people who arrived from an email list is usually simple inside an analytics tool. A segment just means filtering visitors so you only study one group. In this case, the filter can look for traffic that came from email campaigns or links inside newsletters. After the segment is saved, reports will show how these email visitors behave on the site, such as the pages they read and whether they buy something. This helps measure if email traffic is active. Could this segment help guide email plans?
