Direct mail and email—A/B testing
A/B testing compares the effectiveness of two versions of a marketing email
or direct mail copy. The two versions are sent to different groups of potential
customers, and the response to each is measured.

How it works
Direct mail is one of the oldest
forms of marketing. It works on
the basis of sending a product
offer to a large group of consumers
in the knowledge that at least
some will take up the offer and
become customers. Direct mail
relies on lists of names and
addresses, which could be a
company’s existing clients or a
list bought from a specialist agency.
Almost any business, from a small
company to a corporation, may
use direct mail to sell. Typical
companies that sell through direct
mail include mail-order companies,
financial institutions, and nonprofit
organizations seeking donations.
The percentage of people who
respond to direct mail, take up
the offer, make a purchase, and
become customers—a category
known as the conversion rate—is
extremely low, but nevertheless
proves to be profitable.
By targeting a large number of potential customers via mail or email,
marketers hope to convert some into actual customers. This is
achieved through the timing, design, and wording of the message.
