Repetitos
If an executive asks “how healthy is our customer contact database," can you provide more than a vague “it’s pretty good” response? As Forrester's Director of Customer Marketing, I learned: 1. A customer contact database decays 2% monthly and bad customer contact data impacts from 3-5% of annual contract value 2. Bad data is the second biggest challenge when running customer campaigns 3. The third largest buying signal is being a past customer and 20% of new business revenue can come from repeat buyers Repetitos can update and enrich your customer contact database for pennies per name. With a clean database, you are ready for, and we can design a Repeat Sales by Former Customer Contact program.
