Re: Let's try this again.....re:creep? pest?

With reference to this discussion, can someone point me in the direction of
a real/legal definition of spam? The reason I ask is that the company I work
for is setting up shop online in the near future; we've been actively
soliciting people to be put on our mailing list, so I don't worry about
those who've asked to be, but also on that list are some people who (for
example) have bought from us on eBay; those people are also going to receive
a _one-off_ mailing telling them that we're open for business, or they were
until all this started... Obviously we're quite happy to remove anyone from
the list if they want to be, and the msg they get will tell them that, but
having seen some of the vehemence in recent postings, I'm now worried that
maybe just a single mailing to the wrong person might get us blacklisted.
Can someone tell me how (or indeed if) I can notify people about our new
site, without running this danger?

TIA
