# How can I automatically set user emails?

Articles on: [Developers](/en/category/developers-12l9l8o/)

If you are using Crisp on a website where users are authenticated, you may want to set their email so that they don't have to specify it when they start a chat with you.  
  
This method uses the Crisp JavaScript API, that you can call from your own code. Given that you know the authenticated user's email from your code, you'll be able to set it for the Crisp chatbox.  
  
Here's how you would proceed to set the visitor's email:  
  

``` // Feed this call with your own internal email data. $crisp.push(["set", "user:email", "user@gmail.com"]);```

  
  
Let's say you are using PHP, then use.  
  

``` ```

  
(assuming $user_email is your user email.)  
  
  
Here's how you would proceed to get the visitor's email:  
  

``` var visitor_email = $crisp.get("user:email");```
