Here's another way to bring lost customers back to your business: reactivation vouchers. Mail a $20 no-strings-attached voucher to any customers you haven't seen in six months or longer. Few can turn it down, and still fewer will spend only $20.
This effort can be especially successful if you also plan to run sales promotions at the same time. A small, independent music store tried this in November, figuring the period just before the holidays was a good time to have a "25 percent off" promotion. "Absentee" customers were encouraged to use their voucher for any of their sale items (CDs, tapes, videos, etc.) and stock up for the holidays.
