I send out an e-bulletin every couple of months. It's a plain text e-mail newsletter to forum members, although I'm considering moving over to HTML. I'm thinking about selling an ad per newsletter. What do you think? Should it be a text ad? If I move over to an HTML format, should it be a button or banner ad? I would prefer to limit this to one ad per e-mail for maximum benefit for advertisers ... what do you think an appropriate price would be? $0.10 per subscriber? As much as $0.50 per subscriber? Or maybe just $0.01 per subscriber? This is entirely new territory for me so I'm not sure of the going rates.
