The KDP123 monthly email

One email at the start of each month, written by the KDP123 editorial team. No ads, no sponsored tools, and every item links to its source.

• KDP rules that Amazon changed, and the fact pages we updated.
• KDP tool prices and plans that changed, from the changes log.
• The monthly market report, most recently November 2026: categories with room for new books, and new listings.

Prefer a feed reader? Everything, price changes only, monthly reports only, or JSON Feed.

Emails are sent through Resend. Every issue has a one-click unsubscribe link; you can also write to hello@kdp123.com to be removed.
