Don't Give AI Agents Your Personal Email—Give Them a Dedicated Inbox
mqasimca · reddit · 2026-07-06
The author highlights a common anti-pattern: letting an agent directly reuse personal email OAuth tokens to send and receive messages. If compromised by a prompt injection, the agent could send rogue emails under your identity, especially since there is no policy layer between the LLM and the inbox. The recommended approach is to assign the agent a dedicated hosted inbox (a real address, not a borrowed one) and enforce a rule layer before it reads emails (e.g., outright blocking specific sender domains) to ensure true bidirectional communication and security isolation. The author works on the Nylas CLI team.
