Ask What is the best way to segment an email list for better results?

[Newman]

Email segmentation means dividing your subscribers into smaller groups so you can send each group a message that actually fits them. You can segment by things like what they signed up for, what they have purchased before, where they live, or how often they open your emails. For example, someone who bought from you last week should get a different email than someone who has not opened anything in six months. Sending the right message to the right group gets you better open rates and fewer unsubscribes. What do you think is the most useful way to divide an email list?
