JavaScript conditions for checkbox OnLoad

I have a checkbox which determins to hide or make elements vidible. My question is there a way to also include if the checkbox was Originally unchecked on the page load to permanantly remove those elements so they can't be recalled, otherwise continue what is currently below? Hope that makes sense.

function myEmail() {
    var emailBox = document.getElementById("checkemail");
    var emailradios = document.getElementById("emailradios");
    var emailOptOutSix = document.getElementById("emailOptOutSix");
    var emailOptOutForever = document.getElementById("emailOptOutForever");

    if (emailBox.checked == true){
        emailradios.style.visibility = "hidden";
        emailforever.style.visibility = "hidden";
        emailOptOutSix.checked = false;
        emailOptOutForever.checked = false;

    } else {
       emailradios.style.visibility = "visible";
       emailforever.style.visibility = "visible";
    }
}
