// create email headers
$headers = 'From: '.$email."\r\n".
'Reply-To: '.$email."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  

}

Answer 1

I tested your code and have come to the following conclusion.

You have no variable set to $_POST['email'] so that will explain the blank screen, and there is no else conditional statement at the end/outside your code to show/tell you otherwise.

What you "probably" meant to check was to see if the "submit" button was set, as in if(isset($_POST['submit'])) { or add $email=$_POST['email']; under your conditional statement if you want to keep that statement intact.

I added this line at the end of your code: (to test)

else { echo "Sorry, Email variable is not set."; }

And if you were to change this line (to test) if(isset($_POST['email'])) { to if(!isset($_POST['email'])) { and run/execute it without your form, you will see that the mail will be sent, however it may end up in your SPAM box as it did for me, because there was no Email associated with the From:

NB: You are also suppressing errors using the @ symbol for your @mail() function.

So either add $email=$_POST['email']; after your opening conditional statement, or change it to if(isset($_POST['submit'])) { if you're checking with a "named" submit button.

Ie:

<input type="submit" name="submit" value="Submit">

---

<?php
// possible fix - uncomment
// $email=$_POST['email'];

if(isset($_POST['email'])) {

// delete the above line and uncomment this line if checking submit instead
// if(isset($_POST['submit'])) {
