Frequently Asked Questions
What's the easiest way to send newsletters to a Kindle?
InboxToKindle is the least manual option: you get one inbox address, subscribe your newsletters to it, and issues arrive on your Kindle automatically. Amazon's Send-to-Kindle is also easy but requires forwarding each newsletter by hand.
Is there a completely free way to do this?
Amazon Send-to-Kindle is free but manual. Calibre + KindleEar is free and can be automated, but it's self-hosted and mostly RSS-based, so it takes real setup time. InboxToKindle also has a free tier (15 deliveries/month, no credit card).
Which option works for newsletters that don't publish an RSS feed?
InboxToKindle, KTool, and Readwise Reader all work by subscribing with an email address, so they work regardless of whether a newsletter has an RSS feed. Calibre + KindleEar is built around RSS/recipes, so feed-less newsletters need custom scripting.
Can I combine more than one of these?
Yes. It's common to use InboxToKindle for automatic newsletter delivery and a separate tool like Readwise Reader or KTool for web articles and RSS content. They don't conflict with each other.
