“If you deliver the same content to one and all, your email would definitely end up in the junk folder. Segment your contact list into sizeable groups…of similar wants and needs and then create specific campaigns targeted to specific customer groups for a better open rate.”
Split up your email list into groups to ensure more personalized email experiences. Do so by gender, age, location, etc. This avoids email blasts featuring content some or most of your subscribers aren’t interested in, and subsequently limits your number of unsubscribes.
