I would also echo the comments of others on the list who have recommended
against this.  Adding promotional material to emails will quickly
get them marked as spam, and if you add it to emails in transit that you
did not originate, you could quite possibly be breaking the law.

Most likely ‘they’ will start to care when things go terribly wrong, especially 
when reputation damage occurs.

You'd need to roll your own.  It's non-trivial, given the infinite ways
HTML can be malformed.

You could just use "sub filter_end" to insert a new HTML part that comprises 
your header (assuming the content also contained HTML). Easier than modifying 
the existing HTML to add a header.

However... make doubly sure to *ONLY* do this on mails that originate locally, 
from your own domain, and never for any mails in transit, as you'll break DKIM 
signatures on the body. Don't just look at originating IP, look at the From: 
address too.

And best of all, as the previous posting suggested... don't do this at all. It 
will likely just get your domain blocked, either explicitly or implicitly as 
spam-detection algorithms get too many of the same HTML headers, and they start 
treating it as spam.

So, just... no.

You'll probably have to deconstruct append_html_boilerplate's internals, 
and build a custom prepend_html_boilerplate sub to suit.

(Seriously, this is a bad idea.  Marketing emails should be composed 
complete, not modified in transit, and any company that started stuffing 
non-marketing mail full of promotional crap - particularly at the *top* 
of the message, as your client is asking for - is likely one that would 
lose my business, and the same with many other people.  Companies are 
also starting to get fined for pushing the limits like this;  if someone 
has unsubscribed from the newsletter/marketing emails, they DO. NOT. 
WANT. PROMOTIONAL. CONTENT. - and the regulators are listening to 
consumers.)
