How Does Direct Marketing Match Products to Buyers?

Direct marketing matches a product recommendation to a buyer’s purchase history and places it in that person’s inbox rather than a public advertisement.
A customer who bought a camera can receive a lens promotion, while people with no related purchase are left out.
This matching begins with purchase records showing the exact item, model, and category each customer ordered.
The business compares this information with its catalogue of accessories, replacements, and refills.
When it finds a suitable product, it connects the recommendation with the email address saved on the order.
Only customers with a relevant match are added to the mailing list.
In the camera example, the original order identifies the brand and model.
The product catalogue shows which lenses are compatible with that camera.
The promotion is then limited to customers whose records contain a matching model.
