Sending a simple email
Using mail() to send a simple email:
<?php
// The message
$message = "Line 1\r\nLine 2\r\nLine 3";
// In case any of our lines are larger than 70 characters, we should use wordwrap()
$message = wordwrap($message, 70, "\r\n");
// Send
mail('caffeinated#example.com', 'My Subject', $message);
?>
Example 2
Sending mail with extra headers.
The addition of basic headers, telling the MUA the From and Reply-To addresses:
<?php
$to = 'nobody#example.com';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: webmaster#example.com' . "\r\n" .
'Reply-To: webmaster#example.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
?>

Use his line of code:
$to ="example#gmail.com"; // this will be replaced with my actual email
$from ="example#gmail.com"; // this will be replaced with senders email
$headers = "From: ".$from."\r\n";
$headers .= "Reply-To: ".$from."\r\n";
//$headers .= "CC: susan#example.com\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$message = $_GET['Message'];
$subject = "This is a test";
mail($to, $subject, $message, $headers);
