Aw, not all email is spam. Be conscious of the customer; while developers (you) prefer less/no email, many non technical people find it very valuable and have a different tolerance.
And judging by the number of subscribers to Peter Cooper's newsletter empire, and my own humble offerings, many technical people have a different tolerance, too.
That's true, but when you find yourself being the person responsible for implementing and sending bulk email, it helps to keep a sense of humor about it.
