Temporary email API with expiry controls for privacy and QA

Trusted by teams shipping customer messaging

Lifecycle controls

Set mailbox lifetime and ownership as part of the workflow

Temporary inboxes in MailSlurp are private mailboxes with explicit expiry, retrieval APIs, and environment controls so short-lived email stays governed.

Create inboxes with explicit expiry windows

Set `expiresAt` or short-lived retention at creation time so OTP, trial, abuse, and staging flows stop accumulating mailbox state by accident.

Keep every temporary inbox private and attributable

Tag, name, and organize inboxes by environment, test suite, or workflow owner so short-lived addresses still have clear operational ownership.

Wait for matching messages instead of polling public temp sites

Use MailSlurp waits and match filters to receive the exact message you need by subject, sender, unread state, or timing window.

Choose the transport mode that fits the job

Use API-native, SMTP-backed, or virtual inbox patterns depending on whether the workflow needs real delivery, protocol access, or safe no-send capture.

Lifecycle controls

Key workflows

Teams use temporary email when mailbox lifetime should be explicit instead of accidental. That matters in QA, staging, vendor trials, and untrusted flows.

Workflow 01

Set expiry windows and cleanup policy as part of the workflow

Treat mailbox lifetime as an engineering control. Create short-lived inboxes, capture only the messages you need, and let retention stay explicit instead of accidental.
