The First Sentence. Getting your first online dating message started in the right way is extremely important. You want to sound friendly but not crazy. I would recommend starting out with a simple greeting telling the person hello, ask them how they are, and/or tell them your name.

How do you write an opening message on a dating site?

Keep it short. Your first message should make a simple introduction, express your interest in her profile, ask one or two long-game questions about things you share in common, and then simply sign-off with your name. A couple lines, or a paragraph or two is great. When guys write a lot more, they come on too strong.
