“Write naturally. And even though you use their names, do it in such a way that it flows with the conversation. The worst thing you can do is write a stilted email. It comes off as creepy and guarantees the reader won’t click on any links you send their way.”
If you’ve ever communicated with someone who constantly used your name, when a pronoun would have been more appropriate or when it seemed awkward, you may have wished they would have spoken with you more naturally. Be personal, but don’t over do it.
