When I send a cookbook to my Kindle, why do I have to add @justapinch.com as an approved email address and how do I do that?
To prevent spam, a Kindle will only receive files from the email addresses you have authorized. So, if you don't do this our email to you will bounce!
To add your email address, go to Manage Your Content and Devices on Amazon and click on Settings. Add @justapinch.com as an approved email address. You'll need to look for "Approved Personal Document Email List" near the bottom of the page.
