Friends and relatives, introduce me to someone, meet for the first time, send text messages, etc. What should I say?

First of all, make sure whether the other party agrees to contact you and knows you. After that, if the other person is introverted, you can send her name. Hello! Who am I? Do you know I let it go? If you are outgoing and humorous, guess who I am. I'll give you a heads-up, and then type the name of the introducer.
