your name attribute msg calling message in php.
<label for="msg">your message</label> <textarea id="msg" name="msg" spellcheck="true" ></textarea> $msg = $_post['message']; // no need trim message also here...
$message .= "name: $name\r\n"; $message .= "email: $email\r\n\r\n"; $message .= "message:\r\n$msg"; the first occurrence should $message = because there nothing concatenate when hasn't been initialized.
