Contact.suppress

Adds an address to the one list every send reads first, honored by every startup, forever.

Its Inputs, Outputs, Effects and guards quote the hub’s Contact.suppress; this page adds what each Venue honors, its limits and a worked call. It is one of the Verbs of Mailboxes.

Inputs

NameTypeDefaultMeaning
contactContactRequiredThe Contact who opts out.

Outputs

FieldTypeWhat null means
contactContactNever null: the suppressed Contact.

Effects

Action class

None: no approval rule names it, so it runs within its seat’s Permissions and Limits

Modes
  • try: Runs every check and returns the record as it would be; nothing is stored.
  • send: Returns a pending Action at once; Contact.suppressed fires when it is done.
  • do: Waits for the Action to finish and returns the record.
Idempotency

Only with a key: the same Idempotency-Key and input return the first Action, and the same key with other input returns 409.

Saved or shared

Ends every Sequence the Contact is in. Keeps the record: suppression is a row, never a delete.

Emits

Contact.suppressed with { contact }

Performed by

Whichever seat calls it

Price

Free on your own account: the platform charges nothing for the call.

On each Venue

It acts on your own records and reaches no Venue, so every account answers the same way.

What try does

Runs every check the call meets and returns the record as it would be; nothing is stored, sent or posted.

Refuses when

The hub sets no guard of its own on this call: it refuses only on the shared checks every write meets (a missing record, a Permission the seat lacks).

When it waits

Returns in one response; nothing waits.

Example

In send mode the call returns its pending Action at once, and Contact.suppressed delivers the result.

You, to your agent
The Crestline leasing inbox bounced hard: never send to it again.
Response, in send mode
{
  "mode": "send",
  "action": {
    "$id": "https://api.sb/leaseline.app/actions/action_Sd3kQ9vT2w",
    "operation": "Contact.suppress",
    "status": "pending",
    "reason": "running"
  }
}

To retry, send the same Idempotency-Key: the retry returns the first answer for $0. A new key reads again.
