Nothing wrong with your html I tried it. If you have chrome you can use the developer tool to debug and see if your requests are sent and if they are lending on the correct path :

In your mailer.php output the $_POST variable to make sure your data is landing there correctly,

echo "<pre>";
    var_dump($_POST);
echo "</pre>";

You may also need to validate your html :

<form  action="mailer.php" method="post">
  <p>Name:</p>
  <input type="text" name="name" >
  <p>E-mail:</p>
  <input type="text" name="email" >
  <p>Subject:</p>
  <input type="text" name="subject" >
  <p>Message:</p>
  <textarea name="message"></textarea>
  <input class="send" type="submit" value="Send" name="submit">
</form>
