However, I don't do this. If I want someone's name so I can talk to them, I just ask them "what do you want us to call you?" with a single field (and if they enter "Captain HugePenis" then I cheerfully start the email "Hello Captain HugePenis,"). I only use Given/Family if I need their official name for bureaucracy reasons, and then it's very much "what's your name as it is written in your passport/id?", and I don't use it to address them, because it's very easy to get wrong.
