How to spam nicely?

Ok, now that I have your attention.

I'd like suggestions from members of the community on the best way to do
bulk mailings to our user base (not product recommendations specifically or
anything like that), but obvious pitfalls to watch out for.

Our "mass mailing" policy in general has been pretty net-friendly, in that
we only send mail to people who have registered our product at the address
they gave us when they did so (we don't buy lists, etc.), and might be
interested in the specific thing we're telling them about, and we only
attempt to send each person mail once. We also don't do this very often
and keep our mailing lists pretty current.

So, any suggestions to make our having to send a bunch of mail more
pleasant for the rest of the net? If any of you out there have specific
experience with bulk mailing, I'd love to hear about it to avoid stepping
on land mines others have already "detected", etc.

Thanks in advance.

Please don't refer to mailing your existing user base information as
spamming. There is general acceptance of limited commercial speech via
unsolicited email from a vendor to a customer. Examples of this include
security alerts and new product information. One limit is the frequency.
Obviously there is a different limit for security information than new
product information.

We define spaming as mass mailing people who have never contacted you.
This can be commercial or otherwise.

The reason it is important to define spam to not include valid
interactions is to make sure your business customers know that there are
acceptable ways for them to conduct business online that do not involve
mail abuse.
