Mailbox.warm

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

InputsCopy Anchor Link

OutputsCopy Anchor Link

EffectsCopy Anchor Link

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; Mailbox.warmed 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

Raises the daily cap on a schedule while the spam rate stays under 0.1 percent.

Emits

Mailbox.warmed with { mailbox }

Performed by

Customer lead

Price

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

Limits

Fourteen days from 5 sends a day to 25; no cold email leaves a Mailbox still warming.

On each VenueCopy Anchor Link

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

What try doesCopy Anchor Link

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

Refuses whenCopy Anchor Link

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 waitsCopy Anchor Link

Returns in one response; nothing waits.

ExampleCopy Anchor Link

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

Warm up dana@tryleaseline.app to 25 sends a day before any cold email
leaves it.

{
  "mode": "send",
  "action": {
    "$id": "https://api.sb/leaseline.app/actions/action_Sd3kQ9vT2w",
    "operation": "Mailbox.warm",
    "status": "pending",
    "reason": "running"
  }
}

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