Inbox infrastructure
Provision inboxes as a controllable application surface
MailSlurp inboxes carry lifecycle, transport mode, receive-side automation, and downstream hooks so teams can treat email like real infrastructure.
Explicit lifecycle, tags, and mailbox metadata
Set expiry, naming, and tags up front so inboxes stay organized by suite, branch, environment, customer, or workflow owner.
Wait and match on the exact message you need
Use inbox-native waits and matching filters for sender, subject, unread state, and timing instead of brittle sleeps or manual inbox checks.
Attach webhooks, aliases, and send or receive controls
Keep message events, aliasing, latest-message access, and mailbox-level delivery behavior tied to the inbox that owns the workflow.
Inbox infrastructure
Key workflows
When inbox creation and retrieval are manual, core user journeys become hard to verify. API-managed inboxes make email behavior testable and repeatable.
Workflow 01
Generate addresses, receive messages, and assert outcomes in one flow
MailSlurp turns a temp inbox into a controlled test and automation primitive. Provision the address, wait for the message, and inspect the result without leaving your workflow.
Workflow 02
Provision inboxes on demand
Create isolated addresses for users, tenants, releases, or tests without shared mailbox state.
Workflow 03
Route inbound messages cleanly
Push messages, attachments, aliases, and replies into the right workflow without manual triage.
Developer integration
Use inbox APIs, SMTP, and webhook events in the same workflow
Start with SDK helpers for inbox creation and message waits, then move into event-driven routing when the workflow expands.
- Generated SDKs for major languages
- API + SMTP + IMAP support where needed
- Docs-backed patterns for inboxes and message assertions
