      What this check looks for
    Description, as the server wrote it
    Manually check only this workspace's existing inbox now, between scheduled runs. Production key required. Processes up to ten emails with the same matching, approval, authorized autosend, budget and duplicate safeguards as scheduled checks. Existing consented autosend can purchase postage; this tool grants no new consent. A shared worker lease prevents overlapping checks. Server enforces a 60-second cooldown per workspace, including failed attempts; retryAfterSeconds indicates when to retry. Respects admin and workspace pauses. Returns processed count, morePending, updated workspace and demo state; no mailbox credentials.

    Description, as the server wrote it
    No charge. Revise an owned draft's text, font, size, optional color and page limit and optional format settings and letterhead:{id,version} (or null to remove) using its current version. format controls printed fields, greeting/signature, reply cleanup, spacing/margins/page numbers; omitted format/color/letterhead/maxPages preserves the draft's settings. body may be empty. A supplied format fills unspecified fields with defaults, so merge existing settings first to change just one option. Color adds $0.49 for each page; site previews are grayscale when false. Production key required. Renders a new immutable PDF and increments version; always requires fresh review and approval. Cannot edit submitted, uncertain or rejected letters.

    Description, as the server wrote it
    No charge. Rebuild an owned unsent draft using id, exact version and the latest enabled saved version of its associated rule. Retains edited letter text, applies updated addresses, font, color, formatting, page cap and latest active letterhead version (archived presets retain the pinned version), recalculates price and increments version. Always forces approval mode and strips autosend consent; never buys postage, changes credits or dispatches. Production key required. Refuses submitted, uncertain, rejected, deletion-pending and one-time drafts without a saved rule. Optional ruleFingerprint guards an already-reviewed rule snapshot with its resolved latest letterhead reference; concurrent rule/letterhead/draft changes reject the update.

Editing the sender list requires renewed autosend consent. subjectContains holds the subject text; subjectMatch is contains (default) or exact, ignoring capitalization. US return/destination addresses, approval or autosend, font, size and page limit. Optional color defaults false; true adds $0.49 for each page and submits color ink. Site previews show grayscale when false. Optional letterhead:{id,version} pins a saved preset. Optional format controls printed fields, greeting, signature, reply cleanup, spacing/margins/page numbers. First enabled match wins; replacement keeps its position. Default approval, Times Roman 12 pt, 10 pages. Production key required. Autosend requires explicit human recurring-mailing authorization and consent=true; never infer consent. Changes apply to future emails.

Requires a production workspace key and OAuth mcp:read/mcp:write permissions. Production uploads artwork for pricing but takes no payment and sends no mail.

      What this check looks for
    Description, as the server wrote it
    Save or update a workspace postcard rule with matching sender/recipient email, subject contains/exact, US return/delivery addresses, attachment or generated front preference, optional image style instructions, and email-body or custom message. removeImagePrompt defaults true: omit recognizable image-request sentences or labeled prompt blocks from email-derived printed text, while retaining the original body for artwork. False retains them; custom messages and explicit preview/quote message edits are unchanged. postcardType selects single_sided (default for new rules) or double_sided; existing rules without the field retain double_sided. The sender field plus optional additionalSenders (up to 19 exact email addresses) form an OR list. Any listed sender can match; recipient and subject conditions still apply with AND. Matching trims whitespace and ignores capitalization. Existing single-sender and recipient-only rules keep their behavior. Editing the sender list requires renewed autosend consent. All conditions must match; first enabled match wins. Choose mode:approval (default) or mode:auto. Saving any rule requires production workspace authentication and OAuth mcp:read/mcp:write/mcp:send. For artwork:generate in either mode, obtain permission to share up to the first 1200 characters of verified matching emails and saved style instructions with the image service during inbox processing. Approval mode prepares artwork before review without mailing. For auto, obtain explicit recurring authorization for prepaid-credit spending within shared sending limits and terms, then pass consent:true; generated artwork also requires authorization to share matching email text and style instructions with the image service. Consent is required again when updating an automatic rule. At most 25 rules. Saving does not itself send mail, but future verified matching emails may generate artwork, spend credits and mail automatically. Unverified signatures, insufficient credits, exceeded limits and changed rules wait for approval. No automatic card funding.

    Description, as the server wrote it
    Enable Email to Postcard intake after the human requests it, with confirmed:true. Requires a production workspace key and OAuth mcp:read/mcp:write permissions. Creates a dedicated postcard- inbox while preserving the separate letter address. Returns postcardAddressState; inbox is empty until the dedicated mailbox is ready. Retry this tool to check pending setup; never invent an address or send to a pending postcardAddress. Never returns mailbox credentials. Every email delivered to the postcard address enters its separate queue, including BCC delivery; no subject prefix is required. Does not change letter rules, enable postcard autosend, check mail, buy postage or send email.

    Description, as the server wrote it
    Generate and privately save front artwork for an owned postcard email, including emails without attachments. Only after the human explicitly agrees to share the supplied editable email excerpt (message, max 1200 characters) and optional style instructions (max 300) with the image service, pass confirmed:true and a unique UUID requestId. Requires production workspace authentication and OAuth mcp:read/mcp:write. Saved artwork:generate rules prepare verified matching emails during intake, including approval mode; this tool is for explicitly requested generation or regeneration during review. Limit 10 attempts per workspace per hour; retry an interrupted request with the same requestId to recover its saved result. Pass postcardType to match the chosen rule, or omit it to use the email snapshot. Artwork is bound to its size; changing size requires a new generation and requestId. Returns artwork.id and postcardType; use attachment:generated and that artworkId in preview_email_postcard and quote_email_postcard. Existing active checkouts must be revised first; paid/pending orders cannot be changed. No postage purchase or mailing.

PDF edits may omit pdfBase64 to retain their owned artwork. Layout top/bottom/left/right margins are inches; apply:first or all; ruling:none, solid or dashed; lineColor is hex.

    • The name "preview_email_postcard" says "preview": a word for reading.
    Description, as the server wrote it
    No charge. Render an unsaved two-page postcard proof (artwork front and address reverse) for postcardType:single_sided (5.5 × 4.25) or double_sided (8.5 × 5.5) from an owned email id, attachment index, edited message and US from/to addresses. For saved generated artwork use attachment:generated and its exact artworkId. JPG/PNG/WebP images fill the front with centered cropping; PDFs must be one unrotated page matching the selected size. Small cards print the image and message together on the front; the reverse is address-only. Large cards print the message beside the address on the back. Text is limited to 1200 characters and must fit; shorten overflowing text. Omit postcardType to use the email snapshot. Returns a private embedded PDF resource; postage/address marks are illustrative. Workspace authentication and OAuth mcp:read required; staging may preview. No saved quote, external artwork upload, payment or mailing.
