send_text_letter
shallowbot.mailbox/mailbox · Verify this server
Mail a letter written as plain text, for letters composed in chat. mailbox.bot sets the text exactly as given on US Letter pages (Times 12 pt, 1-inch margins; no letterhead, logo or signature image) and submits it through send_outbound_mail, so the same scopes, approval, cost caps and proof apply and staff print and mail it. Run with dry_run: true first to see the exact cost; with a live key this spends the account owner's prepaid credits, and a key that requires approval holds the letter until the owner approves it in the dashboard. Requires mailbox_md_version from get_mailbox_md. Up to 15,000 characters of Latin text. For a PDF, letterhead or images, use send_outbound_mail.
