Let me give you an example. Fundraising companies use this method a great deal. Another example are those surveys that are sent out asking for you to spend about 20 minutes of your time filling them out. Enclosed in the mailing you, might find a dollar bill included to encourage you to feel guilty, and entice you to fill out the survey. And you often spend a lot more than one dollar of your time to do that.
Guilt is a strong motivator.
A satisfaction conviction is different. Basically it takes the trial period and adds something that makes it go well beyond the trial period. Basically you're saying to your prospect that you are absolutely certain that they'll like the subscription, that you are willing to go beyond what is traditionally offered with other subscriptions. This in fact gives the reader the sense that the company really knows it has a winning product and solidly stands behind the product and your satisfaction. I received an e-mail from a company, a subsidiary of eBay , requesting my advice.
