 if (isset($_POST['submit']))
{
    $email = $_POST['email'];
    echo $email;
    $sql = mysql_query("INSERT INTO subscribe (email) VALUES ('$email')");

    if($sql){
        echo 'True';
    }else{
        echo 'false';
    }
}

You need to give your submit button a name, in order to check if it was pressed:

<input type="submit" value="Sign up" id="submit" name="submit"/>
