When texting and calling after the initial meeting, I often use her name to help build comfort and rapport. Do you guys agree with this logic?

Let me give you an example: I am clubbing and K and #-close Cindy. Two days later I send her a text "Hey Cindy! Practising those salsa dancing moves like you promised? -Myname.

vs "Hey, it's Myname, you practising those salsa dancing moves like we promised?"
