On the other hand, I can't stand unsolicited emails from companies I do business with. My first action is to click the unsubscribe link, and if that doesn't work (quite often the case), add the company to my spam filter and hope that their invoice emails still get through.
Unsolicited email is a scourge upon cyberspace. If you as a company want to send me periodic emails, ASK me first. I'll probably say no, but who knows? I might just say yes.
OTOH, I like receiving most email, excepting for the really low quality "v1agra 4 u" spam, or Nigerian 419 scams or whatever. But well written, non scammy email, which is pitching a product or service that I actually might have a need for, doesn't actually bother me at all. And the emails from companies I'm already doing business with are usually very valuable. Amazon, for example, "knows" my musical taste well enough to email me and let me know when there is, for example, a new Motorhead album out. That's cool. Mondo cool.
