Customer TestimonialI just wanted to share with all of you the huge success we’ve had with the Cold Birthday Mailings. For those who don’t know, the company will send gift certificates to people near the restaurant who are not already in your database. They’re valid during the month of their birthday. We had been e-mailing our own certificates, and usually sent out an average of 275 certificates per month. Over the past 4 months, we averaged a 20 percent return of these certificates. This generated average sales of $3789 per month.
