Do while loop

I am using a do while loop in trying to ask the user to enter an e-mail address. I think I have the basic loop, but it doesn't know when to stop because I have not put in a specific requirement to switch the loop to false. Can someone suggest something to tell the loop that the requirements have been met? Here is the code:

var email
var correctEmail
do{
email= prompt("I want to keep in touch with you.  What is your email?");
  if(email != " @....com"){
  alert("Please enter your email.");
  }

}while(! correctEmail);

A couple things are missing from your code but otherwise you are almost there. Your variables are missing semi-colons at the end and you'll need to add an else in your condition to make the correctEmail true; View below.

var email;
var correctEmail;
do{
    email= prompt("I want to keep in touch with you.  What is your email?");
    if(email != " @....com"){
        alert("Please enter your email.");
    } else {
        correctEmail = true;
        alert("Awesome! We'll be in touch soon.");
    }

}while(! correctEmail);

i hope this helps.
