Spam from companies who should know better

Had to approve a email message to foundation-list. Noticed a spam message in the queue from WebEx. Already knew that company, but apparently it is (now?) owned by Cisco. Anyway, there is no excuse for sending this to foundation-list.

The email ends with a sad:

This email may be an advertisement or solicitation. If you do not wish to receive marketing messages from WebEx, please select this link for removal.

Wonder what other solutions like WebEx exists. This as the company I work for unfortunately is a customer of WebEx. :(
