Use Gemini CLI to Put Your Newsletters on Your Kindle
Gemini CLI can make web requests from your terminal, so it can follow the InboxToKindle agent guide and do the setup for you. Paste the prompt, approve the request from your email, add one approved sender on Amazon, and Gemini handles the account, device, schedule and subscriptions.

Frequently Asked Questions
Does the Gemini app work too?
The automatic setup needs an agent that can make web requests, such as Gemini CLI. The Gemini app can read the guide and walk you through the steps.
What do I still have to do myself?
Three things. Click Approve in the email InboxToKindle sends you, which proves the account is yours. Add one approved sender on your Amazon account, because Amazon has no way for any service to do that for you. Then read a 6-digit code off your Kindle so the agent can confirm delivery works. Boox owners skip the Amazon step.
Can the agent read my sign-in codes or reset my passwords?
No. Agents can only see and confirm newsletter subscription confirmations. Sign-in codes, magic links, password resets and other account-security emails are never available to them and always go to your real inbox.
Can the agent pay or upgrade me?
No. The agent can give you a checkout link, but only you can pay. The free plan includes 3 deliveries a month and Pro is unlimited for $10 a month or $100 a year.
How do I remove the agent's access?
Sign in to InboxToKindle, open API tokens, and revoke the token named after your agent. It stops working immediately.
