35 safety-scoped actions

Useful access, narrow boundaries.
Lumail checks the connected user's organization membership on every MCP request. Disconnecting the plugin or removing the owner or admin role revokes access.
OAuth instead of copied secrets
ChatGPT receives a scoped token. Your Lumail password, OTP, Google credentials, and GitHub credentials stay with Lumail.
Draft-safe campaign work
The plugin can prepare and edit drafts, but it cannot send or schedule campaigns.
Safe subscriber and workflow changes
It can add subscribers and tags or prepare Workflow drafts. It cannot unsubscribe contacts, publish workflows, or delete records.
Frequently asked questions
What is the Lumail plugin for ChatGPT?
It connects ChatGPT to one Lumail organization through MCP and OAuth. ChatGPT can read email marketing data and prepare safe changes without requiring an API token.
Who is the plugin built for?
It is designed for SaaS founders, newsletter operators, creators, and lean teams that want to manage campaigns, subscribers, analytics, and workflows conversationally.
Can ChatGPT send a campaign without approval?
No. The OAuth plugin does not expose tools that send or schedule campaigns, publish workflows, delete records, unsubscribe contacts, or change organization settings.
Does ChatGPT receive my Lumail password?
No. You sign in directly on Lumail. ChatGPT receives an organization-scoped OAuth token and never receives your password, OTP, Google credentials, or GitHub credentials.
Which Lumail permissions are requested?
The lumail.read scope covers campaigns, subscribers, analytics, settings, and drafts. The lumail.write scope covers safe draft creation and updates, subscriber additions, tags, and Workflow drafts.
How do I revoke access?
Disconnect Lumail from ChatGPT's plugin settings. Removing the connected user's owner or admin role in Lumail also blocks access immediately.
