Just a sample test of how many of you read this email. Let's see how
good it performs for mailinglists and what comes out.

What you're getting isn't a test of how many people read the mail. What you
got was a count of people who read the mail in MUAs that don't protect against
web bugs.

It's also possible that some small percentage of people are using MUAs that
will pre-fetch the linked files, but then the user discards the mail unread
(I don't know any offhand that do this, but there *was* the brou-ha-ha a while
back about certain browsers that would prefetch linked pages from Google
searches even if the user didn't visit them, causing lots of hits to links
that the user may not even have realized happened, so it's certainly well
within the realm of possibility).
