The new addition to the Tyn Studio family is here: InboxToKindle. It's a simple service that converts email newsletters into clean EPUB files and delivers them to your Kindle. A simple solution to help declutter inboxes and make newsletters more enjoyable to read, in a device designed for reading.
I decided to build InboxToKindle because I kept finding myself in the same situation: I had a long list of newsletters I wanted to read, but I never got around to it. The emails would pile up, and I'd feel guilty for not reading them. I knew there had to be a better way.
The solution was standing in my nightstand: my Kindle. I use it everyday to read books, I like the experience, and I know it works. The missing piece was having the newsletters in the device. So I built a service to make that. Subscribe to a newsletter using a custom email address, and it arrives directly on your Kindle, formatted and ready to read. You want to also read it on your phone? No problem, the same email can be forwarded to your phone's email app.
What it started as an inconvience, turned out into a solution: InboxToKindle.
How It Works
You sign up, get a personal inbox address — something like yourname@inboxtokindle.com — and subscribe newsletters to that address, or forward existing ones there. They arrive on your Kindle, cleaned up and ready to read.
No browser extension. No manual export. No wrestling with send-to-Kindle settings.
InboxToKindle strips the noise — the ads, tracking pixels, banners, sponsored sections — and converts each newsletter into an EPUB sized for e-ink. The result reads like a chapter from a book, not a marketing email. Works with Substack, Beehiiv, Ghost, Medium, and anything else that arrives via email.
You can set instant delivery, a daily digest, or a weekly digest per newsletter. Multiple Kindles supported.
The free plan is 15 deliveries per month — no credit card required. Pro is $10/month or $100/year for unlimited deliveries.
Built at Tyn Studio
Tyn Studio is where I build small, intentional products. InboxToKindle is one of them — it started as a personal solution to a problem I couldn't stop thinking about. Once it worked, I kept using it. The newsletters I'd been ignoring for months became things I actually looked forward to.
That was enough to clean it up and launch it.
If the newsletter pile-up sounds familiar, give it a try.
