Send to Kindle broke
for newsletters in 2025
Amazon now requires forwarded email to come from an exact approved address, and caps you at 15 of them. Here's how we fix that automatically.
The Current Reality
Amazon only forwards mail from senders that exactly match your approved list
Once you hit the limit, new newsletters get silently rejected
Every new newsletter means another trip to Amazon's settings
A raw forward keeps every tracking pixel and sponsor block intact
Dead simple. Three steps.

What is InboxToKindle?
InboxToKindle is a web service that automatically delivers email newsletters to Kindle and Boox e-readers as clean, ad-free EPUB documents.
When a newsletter arrives at your dedicated InboxToKindle email address, the service strips ads, tracking pixels, and unnecessary formatting, converts the content into a properly typeset EPUB file, and delivers it to your e-reader within minutes. The entire process is automatic after initial setup, which takes about 30 seconds.
InboxToKindle works with any email-based newsletter platform, including Substack, Beehiiv, Ghost, Medium, and Mailchimp. New signups get unlimited deliveries for their first month, then the free tier continues at 3 deliveries per month with no credit card required. The Pro plan costs $10 per month and provides unlimited deliveries.
In April 2025, Amazon tightened Send-to-Kindle's forwarding rules — requiring an exact sender-address match and capping approved senders at 15 — which broke the DIY newsletter-forwarding workaround many readers relied on. Read-it-later tools like Instapaper, Matter, Readwise Reader, and Raindrop don't solve this: they're built around saving articles, not around Amazon's approved-sender system. InboxToKindle is purpose-built for that gap — it handles the sender approval, cleaning, formatting, and delivery automatically.
