Use Airtable as the source of truth for recipients, permit tasks, notices, campaigns, or operations records, then call mailbox.bot when a record reaches a mail-ready state.
Airtable automation, script, Zapier, n8n, or agent reads the record.
Letter/PDF is generated from fields and attachments.
mailbox.bot dry run validates recipient, mail class, and cost.
Approval field gates the live send.
Webhook writes tracking and delivery proof back to Airtable.
