A newsletter, asked for like a summary.
Mailcheer connects as a connector in ChatGPT: you describe the campaign, it appears as a draft in your workspace, ready to review.

Connected in 3 steps
Create a key in your Mailcheer workspace: Settings → API → New key.
In ChatGPT, add a connector: Mailcheer's MCP server address, and your key as the authorisation header. The guide gives you the exact snippet.
Ask about your workspace: ChatGPT answers with its name and your verified domains.
What the agent can do
- Read your campaigns, your subscribers and your statistics.
- Write drafts in your voice, based on what you have sent before.
- Add a subscriber — with the confirmation email, as everywhere else.
- Explain your numbers: opens, clicks, bounces, complaints.
- Send, if and only if you ticked that right on the key.
What it cannot do
- Send anything with a key you did not grant sending rights to.
- Send from an address whose domain is not verified in your workspace.
- Write to someone who unsubscribed, or whose address hard-bounced.
- Remove an address from the suppression list — no tool allows it.
- See any workspace other than the one its key belongs to.
Useful access, clear limits
One key, one workspace
Every key belongs to a single Mailcheer workspace. Your other brands or clients stay invisible to the agent, with nothing to configure.
You tick what the key may do
Seven rights, chosen at creation: send emails, read subscribers, change them, read campaigns, send them, read webhooks, manage them. A key without sending rights can never send, whatever the agent is told.
Revoke in one click
One click under Settings → API cuts the key. The next call is refused, and your other keys keep working.
