Frequently asked questions

Can I send any Substack post to Kindle?

Public Substack posts work from a link. For subscriber-only posts you can already read, use Paywalled article mode and paste the full page.

Is this Send to Kindle tool free?

Yes. You can preview and send without an account. Free use is limited to 3 previews and 3 sends per day.

Which article sources work on the free tool?

The free tools support Substack and Medium links. Create a free Inkbox account for more sources, newsletter forwarding, and higher limits.

Do I need to install anything?

No. Paste the article link, enter your Send-to-Kindle address, preview, and send. Your device receives the file by email.

What if the article is paywalled?

If you can already read it while logged in, switch to Paywalled article mode, paste the full page from your browser, and convert from that.
