We are all about e-mail privacy.
Other than when given your expressed permission, we don't have any intention of giving your e-mail address to anyone else, for any reason, ever.
If we should go "out of business," any database of client and customer e-mail addresses might be considered by some to be an "asset" to be sold, but we consider it a trust to be upheld. Your address belongs to you, and we're only entitled to use it for purposes for which you have given permission.
And this policy applies no matter how we may acquire an address. We've recently become aware of a website-based "antispam" tool which has apparently now turned out to be little more than an antispam facade over a website to gather addresses for spamming, not only of the users of the their product, but also addresses of anyone who may reply through the web site. We find this deplorable.
