Iterate over object with Handlebars

I'm trying to iterate over the email key in this object with handlebars, so only the email values will be presented.

 //users object
[{ first_name: 'foo',
last_name: 'foo',
email: 'foo@gmail.com',
phone: '5555' } ]

I've tried to use each like this:

<ul>
 // iterate over the first array
     //iterate over the objects

    <li>: </li> // didn't work
    

Finale result should be :

- email : foo@gmail.com

I guess i could use an if statement but i think concatenation should do the trick
