MailSharks is an MCP server for email campaigns. It lets Claude, ChatGPT and any other AI client run campaigns from your own Gmail over lists in Google Sheets: find the list, write the message, start sending, show the stats.
It connects once and takes a minute. After that you ask your assistant in plain words — it works with the same sheets, messages and campaigns you see in the app.

Copy it — you will need it once.
In Claude — Settings → Connectors → add a custom one. In ChatGPT — connectors in settings. In your own agent — as any MCP server.
No keys to copy: the address is enough.
The client opens a browser, you sign in to MailSharks the usual way and see exactly what the program gets. Press "Allow" — that's it.
Access is tied to your mailbox and revoked in one tap.
The assistant finds the list, writes the message and shows a summary: how many addresses, what subject, how many days it takes. The campaign starts after you agree.

The list of connected clients and the revoke button live in the app, under Settings → Connected AI clients. A revoked connection stops working immediately.
