I did this a few weeks ago. I sent it to 20% of clients I haven't seen for a good while with a stamped addressed envelope. So far I've only had about 20% of them back, which was a bit disappointing. I'm also giving it to regular clients and they can either give it back or send it later. This is the letter I sent out.
Having been open for over 3 years I thought it was high time that I asked you, the customer, what you do and dont like about EveryBodies and the service I provide. Be as honest as you want as this will only go to improve what I offer and its anonymous. Ive enclosed a £5 gift voucher as a thank you.
