When you sell a product it's not only important to know who bought it, but also why they bought. What motivated them to buy your product, what motivated them to buy your product over some one elses, and what you can do to motivate them into a repeat purchase in the future.
Almost every significant purchase made involves either saving money or time. If you can include one, or better yet, both of these powerful motivators in your offer, you're success rate will likely increase. When people feel like they are saving money they are more inclined to make a purchase immediately rather than put it off and eventually forget about it. This is especially effective with limited time offers that initiate action within a certain time frame. Demonstrate that your product or service can save them time, make them more efficient, and allow them to get more business done during the day and you have a winner. Integrate these two buying motivators in the same offer and watch your direct marketing campaign soar.
