This should have been a no brainer, and I can't believe I am having to write it at all. But after dealing with a client this last week, I guess that it isn't so obvious. Here is the rule: If you don't want to be perceived as spam, then don't spam! That is rule number one. OK, you think everything you have to say is valuable and that everyone should hang on your every word. Goody for you. You customers don't agree, and it is their decision.
