When you start learning more about the people on your list, you can send them more relevant communications by adjusting your message to make it more personal.
If you had a group of people who prefer beef and another group that prefers chicken and you are promoting a new steak feature, what would you do?
Some might say you only send the new steak feature only to the people who prefer beef.
Why not send it to the people who prefer chicken and adjust the message?
"Hi Joe,
I know you love chicken, but if you were going to have one steak this year, this would be it.
Check out our new steak feature!
We are looking forward to your next visit.
Your Restaurant"
