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    lt input type  checkbox  name  newsletter    value  newsletter  checked gt i want to sign up for newsletter lt br gt    to this    lt input type  checkbox  name  newsletter  value  newsletter  checked gt i want to sign up   for newsletter lt br gt                                            remove square brackets here
