If the checkbox is checked you will get a value for it in your $_POST array. If it isn't the element will be omitted from the array altogether.

The easiest way to test it is like this:

if (isset($_POST['myCheckbox'])) {
  $checkBoxValue = "yes";
} else {
  $checkBoxValue = "no";
}

For your code, add it immediately below the other preprocessing:

$name = $_POST['name']; 
$email_address = $_POST['email']; 
$message = $_POST['tel']; 

if (isset($_POST['newsletter'])) {
  $newsletter = "yes";
} else {
  $newsletter = "no";
}

You'll also need to change the HTML slightly. Change this line:

<input type="checkbox" name="newsletter[]" value="newsletter" checked>i want to sign up for newsletter<br>

to this:

<input type="checkbox" name="newsletter" value="newsletter" checked>i want to sign up   for newsletter<br>
                                      ^^^ remove square brackets here.
