Email status reference - Apollo Deploy

The current email record exposes 15 statuses. Statuses describe Signal’s latest known state; the timeline preserves the sequence of observed events.

Admission and processing

Status	Meaning
`queued`	Signal accepted an immediate message and queued provider work.
`sending`	Signal started the provider handoff and has not recorded a later outcome yet.
`scheduled`	Signal is holding the message until its requested send time.
`test`	Signal exercised test behavior without real recipient delivery.

Provider and recipient outcomes

Status	Meaning
`sent`	Signal recorded a successful handoff to the sending provider.
`delivered`	The recipient mail server accepted the message.
`opened`	The configured open-tracking pixel was loaded.
`clicked`	A configured tracked link was followed.
`bounced`	A bounce event was recorded for the recipient.
`complained`	A complaint event was recorded for the recipient.

Stops and uncertain outcomes

Status	Meaning
`cancelled`	A scheduled message was cancelled before provider dispatch.
`suppressed`	Signal blocked the recipient because suppression state applied.
`rejected`	Signal recorded a deterministic provider or policy rejection before successful handoff.
`failed`	Signal or the provider could not complete the send and recorded a failure.
`indeterminate`	The provider handoff outcome could not be determined confidently, including an uncertain response without a provider message ID.

How to investigate

Open the message and read the latest status and error.
Read the timeline from the last successful transition to the first failing event.
Check the recipient’s suppression and contact preference state.
Check whether the From domain remains verified.
Correlate the Signal email ID with your request logs and webhook event IDs.

Treat indeterminate differently from a clear rejection. It means Signal cannot prove whether the provider accepted the handoff. Do not create a fresh duplicate send automatically; inspect the record and use your original idempotency key for an admission retry.

opened and clicked are tracking observations. Privacy systems and automated link scanners can produce those events, so they are not guaranteed human actions.
