If you're thinking about pricing your news letter on like a performance basis, i think that can be more trouble than it's worth. I also think some brands, kind of, going back to the mediacate comet, they'll be so invested in how they got started and why they got started, and their audience. Another thing you can do if you're unsure, i'm pricing. If you have a pretty decent amount of unsold inventory month over month, and you're thinking this dollar amount might feel uncomfortably high to you, i would let the brand knoweif they're kind of having to feedback to you.
