  "instructions": "Mailcheer is an email platform. This connection gives access to ONE Mailcheer workspace — the one the key belongs to.\n\nCall `get_account` first: it tells you which workspace, which scopes, which sending domains are verified, and which sender addresses exist. Without it your first send will fail on the domain.\n\nTwo actions cannot be undone: `send_email` (the email leaves immediately) and `send_campaign` (the message goes to ALL active subscribers, or only to the active subscribers among the addresses given in `to`). Always ask for explicit confirmation first, stating how many people will receive it — `preview_campaign_send` gives that number without sending anything.\n\nNever use `double_opt_in: false` on your own initiative: by default a new subscriber receives a confirmation, and that step is what protects the workspace's sending reputation.\n\nThe full reference is in the `mailcheer://docs` resource.",
