By having us handle the promotion, fulfillment and renewals, you can zero in on the most important aspect of publishing success, editorial. It's the most important aspect because if the editorial product isn't good, renewals will fall. And in the big picture, as renewals go, so goes your publication. World class customer service. No one handles subscribers with more respect than we do.
Many publishers hire just a fulfillment company.
Or someone to handle just promotions. There's no problem with that except that usually, somewhere along the line, coordination breaks down. You may want to run a special promotion and the fulfillment company can't handle it. Or they want to charge more. All from the same building.
