}Sends a reminder to someone who has a public UnRemind.me page, on behalf of the person you are helping. It does NOT appear in the recipient's list immediately: it lands in their 'Submitted to you' queue for them to approve, edit or decline. You need the recipient's username, which the person you are helping will have — it is the last part of their page URL, e.g. unremind.me/johndoe. Do not guess a username: there is deliberately no lookup, and a wrong guess sends someone else's reminder to a stranger.
| Argument | Type | Description |
|---|---|---|
| notes | string | Detail the recipient needs to act on it: context, links, what done looks like. Optional but strongly preferred — a bare title often gets declined. |
| title* | string | Short and action-oriented, e.g. 'Send the signed lease back'. This is what the recipient sees first. |
| due_at | string | ISO 8601 with a UTC offset, e.g. 2026-09-02T14:00:00-04:00. Only set this if a real deadline was stated; an invented one is worse than none. |
| page_key | string | Only needed if the recipient has made their page private. It is part of the link they shared. Omit otherwise. |
| username* | string | The recipient's UnRemind.me username — the last part of their page URL, e.g. 'johndoe' for unremind.me/johndoe. |
| via_channel | string | How you are reaching us, e.g. 'Claude Code'. Shown to the recipient as the CHANNEL the person used, never as the sender. Optional. |
| submitter_name | string | The name of the PERSON you are sending on behalf of — not your own name as an agent. The recipient sees this. Required UNLESS they have set it in this server's configuration. |
| submitter_email | string | The sending person's email — how they receive the status link and the recipient's answer, and what lets them raise their sending allowance by signing in. Required UNLESS they have set it in this server's configuration. Ask them for it; never invent one. |
