Another wrong email address...

Yet again I've been sent email for another Marcus Rowland. I wouldn't even bother mentioning it, it happens so often, but this one appears to be a scan of the results of a blood test done by an American lab which an online search tells me does a lot of oncology testing, and there appears to be no way to reply to it (it was sent from a scanner that doesn't take incoming messages). I really do not want to give these people all of the personal details their contact form demands simply to say "sorry, wrong address."

Any suggestions, other than ignoring it and hoping that they'll sort it out for themselves?
