Server instructions

Mailcheer is an email platform. This connection gives access to ONE Mailcheer workspace — the one the key belongs to. Call `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. Two 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. Never 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. The full reference is in the `mailcheer://docs` resource.
