Request - Include contact name when sending message to many people

Hi Team,

I want to send a common message with personalization to many people. For example, a Christmas message.

How can I personalize the message without having to schedule separately for each person?

• Let's say this is the message to be sent to 50 people - "Dear XYZ, Merry Christmas!"
• Where XYZ is replaced by contact name to who message is sent.
• If contact is saved as Mary, message to her is "Dear Mary, Merry Christmas!".
  And if contact name is David, message to him says "Dear Davi, Merry Christmas!"
• Is there some sort of code we can write or something? like Dear <Contact First Name>...etc

Appreciate your help very much! thanks
