meaning - Can't come up with the correct sentence

I have some trouble coming up with the right sentence for a form input where I'm asking a user's first and last name.

What I'm actually trying to say is that the name the user is filling in will be used to name this person, in for example emails.

Right now I have:

We will reference to you by this name.

But it doesn't sound right to me, and I think it isn't.
