Email statuses

The lifecycle statuses of an email log and what each one means.

Every send is recorded as an email log with a status. Status is advanced independently by sending, tracking and provider notifications — it is not a strict linear state machine.

Statuses

Status	Meaning
`QUEUED`	Log created; the send was accepted (async)
`SENT`	Handed to the sending transport successfully
`DELIVERED`	The provider confirmed delivery to the recipient's server
`OPENED`	The open pixel was hit (first open only)
`CLICKED`	A tracked link was followed (first click only)
`BOUNCED`	A permanent (hard) bounce; soft bounces record a reason but keep the prior status
`COMPLAINED`	The recipient marked the message as spam
`FAILED`	The transport raised an error; the send may be retried
`REJECTED`	The recipient is on your suppression list — never sent (terminal)

CANCELLED exists in the status enum but applies to scheduled emails and campaigns, not to individual send logs.

Notes

OPENED, CLICKED, DELIVERED and BOUNCED are not mutually exclusive steps — analytics treats them as counters, and an already-opened log is not moved back to DELIVERED.
A hard bounce or complaint also adds the address to your suppression list.
Bounces carry a type — HARD, SOFT or COMPLAINT — with a reason and timestamp.

See Email logs to query statuses and the Analytics API for aggregates.
