Direct Broadcast Without Duplicates

Confirmed audience → delivery via API without repetitions

A robot freezes the audience, guides it through a confirmation gateway, and two secure channels with a recipient log

In short

An intermediary constructor hides the real audience, delivery status, and behavior after failure, making mass runs difficult to verify and safely resume.

Outcome

A private conveyor freezes the audience, requires confirmation, adheres to official API limits, and maintains an idempotent-ledger for each recipient.

How the automation runs

Trigger

Operator created a campaign and requested a dry-run for an authorized audience

Automation steps

  1. Calculates audience and re-applies consents and unsubscribes
  2. Captures a single run and freezes a snapshot
  3. Shows a signed approval card before any message
  4. Sends via official APIs with limits and retries
  5. Records outcome for recipient and safely continues after failure

Human check

The operator confirms a specific snapshot and first runs a small pilot; a complaint, limit exceeding, or increased errors trigger stop-control, not automatic expansion.

Outcome

A private conveyor freezes the audience, requires confirmation, adheres to official API limits, and maintains an idempotent-ledger for each recipient.

Using it

When to use it

You have your own audience in several messengers and need to control dry-run, delivery, rerun, and unsubscribes on your side.

How to verify

Snapshot size matches control query, pilot delivered as expected, rerun does not create duplicates, and stop-control terminates new attempts.
