I didn't mention anything about selling it. I don't want to get future e-mails from them.
If I send someone an e-mail (versus filling out their form), at least it makes me feel that they have to take an extra step to put it in their database. I'm just giving you my perception of forms. I don't fill them out, except if I've already decided to buy something.
By the way, I get almost ZERO junk e-mail (less than 3 a day anyway - compared to other people that seems to be pretty good).
