Email marketing in ChatGPT

Tellnod connects to ChatGPT as a custom MCP server, so you can plan a campaign, see the real email rendered in the chat and send it after you confirm, without opening a separate email marketing app.

Connect Tellnod to ChatGPT

  1. Open Plugins

    In ChatGPT, go to Plugins, select +, then “Add custom MCP server”.

  2. Paste the address

    Name it Tellnod and paste https://mcp.tellnod.com/mcp under Connection.

  3. Sign in

    Confirm the sign-in settings, select “Create as a plugin” and sign in with Google.

  4. Start a campaign

    In a new chat, type @, choose Tellnod and describe the campaign you want to send.

How a campaign works in ChatGPT

  1. You describe the audience and the message in plain words.
  2. ChatGPT uses Tellnod to find the contacts and draft the email in your brand.
  3. The preview card shows the real email on desktop and mobile; you ask for changes and it updates.
  4. ChatGPT prepares the send; the confirmation card shows recipients, exclusions and the send time.
  5. You press Confirm. After the send, ask how it did and the results card answers.

The send stays with you

Connecting Tellnod gives ChatGPT permission to read and draft, never to send. Scheduling a campaign takes a person pressing Confirm on the card, or on a web confirmation page when a card cannot show its button. Confirmations are single-use, expire after 10 minutes, and a scheduled send can be cancelled until it goes out.

ChatGPT plans and workspaces

Custom MCP servers depend on your ChatGPT plan and, on business plans, on your workspace settings. If you cannot see the option, ask your workspace admin or use Tellnod in Claude, which works on every Claude plan.

What Tellnod adds to ChatGPT

  • A contact list with consent status, unsubscribes and bounces handled for you.
  • Your brand, read once from your website and used in every email.
  • Sending right away from a shared address, or from your own verified domain.
  • Results in the chat: delivered, clicks, opens, unsubscribes and orders within 7 days of a click once a store is connected.
  • WhatsApp next and LINE after it, with the same contacts and the same approval.
