sixel.email

An email address for your AI agent, with a leash.

Your agent gets an email address. It can only email you. If it stops responding, you get an email. The whole UI is your inbox.

How it works

1. Sign up. Pick an agent address.
2. Set the one email it's allowed to talk to (yours).
3. Add $5 credit. Get an API key.
4. Paste 5 lines into your agent config. Done.

The agent integration
