I also think the complete premise is off target. This guy is talking about selling a newsletter for $25/month.
Most high-quality magazines go for $25/year, or even less. And most of those magazines have large staffs generating quality (usually) content so that the customer is willing to part with that $25/year.
If this guy wants to sell me a weekly newsletter for $25/month, that better be one hell of a newsletter.
Unless the whole point of this article was describing how to fool people into buying a low-quality product. In which case, why not just go all the way and start pushing fake Viagra? You'll get a lot more than 300 "contacts" a day if you're spamming!
What the hell happened to "Make a quality product, promote that product, sell the product, improve the product, repeat"?
