The number of sales you experience will vary based on your industry, your target audience, your customer acquisition tolerance, and your appetite. While no two campaigns are the same, it’s common for our clients to see thousands of new customers from each direct mail campaign. We’ve seen several clients gain over 100,000 new clients in a single year from direct mail! A good rule of thumb is that mail can drive 25-40% of all new customer acquisitions for your business.
