This past season, I did virtually all my shopping on Amazon. They make it so easy, don't they? Only when you're curious about what to get for that impossible-to-buy-for individual, they pop up in the wholesale formula review reddit (Find Out More) email box of yours with a very helpful reminder. When you do not like what they are suggesting, that is okay - they'll recommend products that other people liked.
It is a genius business model. They draw you farther and farther into the world of theirs, get more and more info about you until they understand you better than you understand yourself. Due to this smart, top-of-mind design, they've made billions.
Believe it or not, you are able to apply some of those same concepts to your individual direct mail marketing.

Understand your customer.
Be ubiquitous.
Put in a smile.

While the business of yours might not exactly have the business of delivering music and books, you are able to still have a number of pages from the Amazon playbook and find out actual achievement.
