# Email Manual Actions And Storage > Focused Email reference for action inputs, folders, check filters, delivery, self-send/time capsules, contacts, attachments, and mailbox persistence.

This page covers action details that need care; action input objects remain closed. Omitted optional values use defaults, and explicit `null` is omitted at the family boundary. ## Send ```python email(action="send", input={ "address": "peer", "subject": "status", "message": "ready", "cc": ["human"], "bcc": [], "attachments": [], "delay": 0, "mode": "peer", "type": "normal", }, reasoning="report status") ``` `address` is a bare peer name, or an explicitly authorized absolute path with `mode="abs"`. CC is visible to recipients; BCC is stored only in the sender's copy. `attachments` are source paths: for non-self POSIX delivery the adapter validates every path before publishing that recipient's inbox entry, copies files into recipient-local `attachments/`, and suffixes duplicate basenames. Source paths are resolved/read at delivery time, so preserve their bytes until delivery; there is no send-time frozen snapshot. No attachment-size or source-root-containment limit is enforced: select only files you are authorized to share. A self-send bypasses this adapter and does not validate or copy attachments; its inbox note can retain a missing source path. Do not treat self-mail as an attachment backup. The message body is capped at 50,000 Unicode characters and is rejected, not truncated, when oversized. Each recipient's outbox is written before its thread starts; the unified sent record follows all thread starts. `status="sent"` is scheduling, not acceptance. Use a non-negative integer `delay` for one future attempt, not tool execution; the schema does not enforce a non-negative bound. For partial failures and restart limits read [Notifications and delivery](../notifications-and-delivery/SKILL.md). The duplicate guard compares recipient/body, not the whole message; see [Settings reference](../settings-reference/SKILL.md#duplicate-send-loop-guard). ## Check and search `check` lists newest first from `inbox`; `folder` may be `inbox`, `sent`, or `archive`, and `n` defaults to 10. Its only filter object supports: - `sort`: `newest` (default) or `oldest`; - `from`, `subject`, `contains`: case-insensitive substrings; - `after`, `before`: ISO 8601 timestamps; - `unread_only`, `has_attachments`: boolean selectors; - `truncate`: preview characters, default 500; `0` requests the full body. Email may trim a large `check` result to its token budget and reports that fact. `search` takes a regex `query` and optional `folder`, searches sender/subject/body, and rejects invalid regex; it accepts neither `filter` nor `n`. With no folder, `search` covers inbox + sent. Folder-less `read` searches inbox, sent, then archive; only inbox records are marked read. ## Read, mutate, and contacts - `read` takes mailbox IDs, returns source records including attachments, and marks inbox IDs read. `dismiss` marks handled inbox IDs read without returning bodies. - `reply`/`reply_all` take one ID and a message; routing and subject derivation are in [Addressing and replies](../addressing-and-replies/SKILL.md). - `archive` moves inbox IDs to `mailbox/archive` and removes them from the read set. `delete` permanently removes inbox/archive IDs and refuses `sent`. - `contacts` lists the private book; `add_contact` upserts; `remove_contact` deletes; `edit_contact` changes only supplied name/note fields. Contact writes use a temporary file and atomic replacement. IDs must come from this agent's current notification or mailbox result. Stale or foreign-working-directory IDs have no meaning and produce a not-found hint. ## Self-send and time capsules An already-delivered self-note survives molt; `dismiss`/`read` clear unread status but retain the message, `archive` moves it, and `delete` removes it. Before delivery, a delayed self-note depends on the current mailman daemon thread staying alive; outbox persistence does not make that timer survive process exit. Use it as a one-shot time capsule, not delayed tool execution or a durable scheduler. Recurring or restart-resilient work belongs to `shell-manual`. ## Mailbox layout and retention Paths are relative to the agent working directory: ```text mailbox/inbox//message.json received mail mailbox/sent//message.json one sent record per call mailbox/archive//message.json archived inbox mail mailbox/outbox//message.json pending/delayed send mailbox/read.json read-ID set mailbox/contacts.json private contact book .notification/email.json producer-owned unread mirror ``` Message JSON is UTF-8. Non-self POSIX recipient entries use staging + atomic publication; self-inbox, outbox and unified sent records use direct writes. `read.json` and contacts use temporary-file replacement. BCC is not exposed in recipient payloads. Do not infer crash durability from these different write paths. ## Cleanup / Footprint Email leaves the paths above, recipient attachment snapshots, and ordinary Agent logs/bounce events. Before mailbox retirement or when attachment growth matters, inspect only this Agent's `mailbox/` and `.notification/email.json` with the shared read-only count/byte recipe in `skills-manual` → `reference/cleanup-footprint-contract.md#shared-footprint-check-recipe`. Inspect metadata without broadcasting private bodies/addresses. Keep sole copies of decisions, handoffs, attachments, contacts and pending/evidence records. Show a dry-run report listing what would stay or go, obtain explicit human consent, then prefer authorized `archive`/`delete` actions over filesystem removal. Do not clean active outbox state. Cleanup is optional; without consent stop at the report. If recording the audit, separately opt into the shared `logs/cleanup.jsonl` append (timestamp, Email label, dry-run/apply, count, bytes, non-secret path summary, approval). Inspection alone writes nothing; approved apply records actual results.
