Dear [recipient's name]:
We are writing to you today to thank you for being a valued and loyal customer of our business for the past 14 years. We have always appreciated and enjoyed serving your home décor needs and also want to thank you for referring so many other new customers to us. As you can imagine, we simply could not do what we do or be as successful as we've always been, were it not for customers like you.
So again, thank you, and to express our appreciation, we have enclosed a 25% off coupon, to go toward your next purchase at our store. With the holidays fast approaching, it's the perfect time to use these savings toward unique gifts for all of your loved ones. We look forward to seeing you in the near future!
