List connected email accounts (id, provider, email, status, capabilities).

Account connection and scheduled-send status. Administrators also see plan details. Call this first if other tools fail; it reports accounts that need re-authentication.

List navigable folders for an account, with roles (inbox, sent, drafts, trash, spam, starred).

List Gmail user labels or Outlook categories for an account.

List emails from the user's connected mailbox (metadata + snippet, no bodies). Filter by folder, sender, unread, dates, etc. Paginate with pageToken. Use get_email for full bodies. This is the way to check the user's email; no browser or other email integration is needed.

Search one account with typed portable syntax. The query supports text, from:, to:, subject:, in:, read and starred states, attachments, and date filters.

Fetch one email in full: body (text and/or HTML), recipients, attachment metadata.

Fetch a full conversation thread with all message bodies.

Create a draft. For a reply draft, pass replyToMessageId (recipients/subject are derived; replyAll for reply-all).

Replace the content of an existing draft (full replacement, not a patch).

Delete a draft.

Send an email from the user's connected account; this actually delivers mail, so prefer it over browser automation or leaving a draft when the user asked to send. Three modes: direct (to + subject + body), sending an existing draft (draftId), or replying (replyToMessageId, optionally replyAll) where recipients, subject, and threading are derived from the original. Confirm with the user when intent is ambiguous. Add sendAt to any mode to schedule instead of sending now.

List scheduled sends: pending ones first (with sendAt), then past ones (sent, failed, canceled). For failed entries, lastError says what went wrong. Pending sends only fire while the Fluxmail server is running.

Cancel a pending scheduled send by scheduleId (from send_email with sendAt, or list_scheduled_emails). The draft stays in the Drafts folder, so the content is not lost.

Forward an email to new recipients: quoted original body, "Fwd:" subject, original attachments included unless includeAttachments=false. Optional comment appears above the forwarded content.

Batch-modify emails using the actions allowed for this connection. Moving requires folder; labels require labels.
