InboxToKindle
One inbox email delivers every newsletter to your Kindle
Send to Kindle works for the odd document, but not for a newsletter habit: every sender must be on your approved list, and it holds 15 addresses. InboxToKindle gives you one private address that is already approved. Subscribe with it (Substack, Beehiiv, Ghost, any email newsletter) and each issue lands on your Kindle or Boox as a clean EPUB, without ads or tracking. Free for 3 deliveries a month, no card. Pro is unlimited for $10 a month. Or try the free Substack-to-EPUB converter, no account.
Hi everyone, I'm Luis, the maker of InboxToKindle.
I built it because I subscribe to more newsletters than I ever read. They pile up in my inbox between everything else, and the long ones deserve better than a phone screen. I wanted them on my Kindle, where I actually read.
Amazon's Send to Kindle can do that for one document at a time, but every sender has to be on your approved list, and the list holds 15 addresses. That doesn't work for a newsletter habit.
So InboxToKindle gives you one private email address that is already approved. You subscribe to newsletters with it, or forward them to it, and each issue arrives on your Kindle or Boox as a clean EPUB, without ads, tracking pixels or email clutter. It works with Substack, Beehiiv, Ghost and anything else that arrives by email.
So far it has delivered more than 3,000 issues from over 600 publications.
If you want to try it without signing up, there's a free converter that turns any public Substack post into an EPUB: https://inboxtokindle.com/tools/...
Pricing is simple: free for 3 deliveries a month with no card, and $10 a month for unlimited.
I'll be here all day. Tell me what's missing or what didn't work for you. That's what I most want to hear.
Hi Product Hunt 👋 I'm Luis, the maker of InboxToKindle.
I built it because I kept subscribing to great newsletters and then never reading them. They got buried in my inbox between receipts and notifications. On my Kindle, I actually finish them.
How it works: you get one address (yourname@inboxtokindle.com) and subscribe to newsletters with it. Every issue arrives on your Kindle or Boox as a clean EPUB, with no ads, tracking pixels or "view in browser" clutter. It works with Substack, Beehiiv, Ghost, Medium and anything else that sends email. You can get each issue instantly or as a daily or weekly digest.
Something new, shipped this morning for launch day: you can let your AI agent do the setup. Tell Claude Code, ChatGPT agent mode, OpenClaw or Gemini CLI something like "set up InboxToKindle for me and subscribe me to these newsletters." The agent creates your account, adds your Kindle, sets your schedule and confirms the subscriptions. You click Approve once and add one approved sender on Amazon, the only step Amazon doesn't let anyone else do. Agents can confirm newsletter subscriptions, but they never see sign-in codes or password resets.
The free plan includes 3 deliveries a month, no card needed. Pro is 10 USD a month for unlimited.
I'd love your honest feedback, especially:
- Which newsletter would you send to your Kindle first?
- If you try the agent setup, where did it get stuck?
I'll be here all day answering every comment.
