Fulfill Inquiries Fast

6. Re-mail the non-converting inquiries at least three times.

I once tested fulfilling catalog requests via first-class mail versus Standard A. I found the conversion rate increased by 20 percent with first-class mail, which was more than enough to offset the additional postage cost. While you may not experience the same increase, it’s safe to say you’ll maximize your conversion rate if you boost the rate at which you fulfill catalog requests.
