title: Sending an email after form submission
body: <p>I would like to know how I would send an email to a user after they submit a form to my website..</p>
  
  <p><strong>Background:</strong>  I am relaunching a site that my father shut down in 2002, we currently have a welcome/splash page that says the site is going to coming back soon. This page asks the user to input their email to be added to the launch list. This form uses a "web form mailer" as below:</p>
  
  <pre><code>&lt;form action="/webformmailer.php" method="post"&gt;
  </code></pre>
  
  <p>Their email is sent to a inbox that we chose.  What I would like to do is send this user an email that says thanks, look forward to updates, thanks again, etc..</p>
  
  <p>How would I go about this? I have no idea and any help would be much appreciated!!</p>
