php - imap_fetchbody message is encoded

I'm building a web app where users will be able to see emails sent to their account. I am having some issues regarding the encoding of their messages.

As a test, I just received a registration email from a website. The mail contained HTML.

It should look like this:

That is how it looks in my inbox; although, on my website it looks like this:

This is my PHP code:

$openmail = imap_open($dns,$email,$password ) or die("Cannot Connect ".imap_last_error());

if ($openmail) {
  echo  "<div class='noti success'>You have ".imap_num_msg($openmail). " messages in your inbox</div>\n\r";
  $tot=imap_num_msg($openmail);
  for($i=$tot;$i>0;$i--) {

    $header = imap_header($openmail,$i);
    echo "<br>";
    echo $header->Subject." (".$header->Date.")";
    $body = imap_fetchbody($openmail, $i,'1');

    echo "<div class='faq-tile'>$body</div>";
  }
  imap_close($openmail);
}

The $body variable, is the one printing out the body of the mail.

The content you get out of imap_fetchbody is base64 in this instance:

$body = imap_fetchbody($openmail, $i,'1');

if (preg_match('/^([a-zA-Z0-9]{76} )+[a-zA-Z0-9]{76}$/', $body)) {
    $body = base64_decode($body);
}

echo "<div class='faq-tile'>$body</div>";
