Check below updated code:
<?php
if(isset($_POST['add']))
          require_once('mysqlCreds.php');
          $email = trim($_POST['email']);
          if($email == '')
                    header('Refresh: 5; url=http://szeryk.com/homepage');
                    echo "<div style='color: #FFFFFF;'>Please enter an email address to subscribe.</div>
                    echo "<div style='color: #FFFFFF;'>If you aren't re-dreicted in a few seconds please click <a href='http://szeryk.com/homepage'>here</a></div>";
          $result = mysql_query("SELECT * FROM emailList WHERE email = '".$email."' LIMIT 1")or die(mysql_error());
          if(mysql_num_rows($result) > 0)
                    header('Refresh: 5; url=http://szeryk.com/homepage');
                    echo "<div style='color: #FFFFFF;'>We are sorry, but this Email address is already subscribed.</div>
                    echo "<div style='color: #FFFFFF;'>If you aren't re-dreicted in a few seconds please click <a href='http://szeryk.com/homepage/'>here</a></div>";
          else
                    mysql_query("INSERT INTO emailList (id, email) VALUES('', '".$email."') ")or die(mysql_error());
                    header('Refresh: 5; url=http://szeryk.com/homepage');
                    echo "<div style='color: #FFFFFF;'>Thank you for subscribing to the newsleter!</div>";
                    echo "
                    echo "<div style='color: #FFFFFF;'>If you aren't re-dreicted in a few seconds please click <a href='http://szeryk.com/homepage'>here</a></div>";
?>
