To contact readers of a current book with a discount offer for a new book, please follow these steps:

1. Create a discount coupon for your current book.

2. Publish a new version of your old book and include a "Release Notes" message that will be sent to people who have opted in to receive these messages. (If you are using our Upload writing mode, please go here instead.)

PLEASE NOTE YOU SHOULD ONLY DO THIS VERY RARELY! It is not ok to use this feature to spam your readers with offers.

3. You can also use one of these other methods to contact your readers.

4. Finally, if you're interested in learning more, here is an article with some more details of how you can contact Leanpub readers, and what some of our policies are on this matter.
