In the interests of letting as many people know this as possible, so as to be compliant with new data protection legislation, here is the letter I recently sent out to subscribers. It's probably a little bit boring but is also intended to be reassuring.
Dear Clarendon House Publications Customer, Inner Circle Writers’ Group member and E-newsletter Subscriber,
MY COMMITMENT TO YOUR PRIVACY
Over the years, I have been happy to provide you with irregular complimentary e-newsletters or my on-line Inner Circle Writers’ Group pages on social media, and I keep in touch with you on an irregular basis by email, letting you know of activities as well as various developments in Clarendon House Publications and imminent new book releases, competitions, promotions and special offers. I hear back from many of you on a regular basis with news of your writing and works which you kindly send to me.
I only process financial information according to your instructions and will only ever use payment card information in accordance with established standards and the requirements of our payment processor.
