Product features

MailSlurp capabilities for inbox auto replies

Build policy-driven email auto replies with routing rules, escalation paths, and audit trails for support, operations, and partner workflows.

Inbox and catch-all auto-reply rules

Create reply rules on specific inboxes or catch-all addresses so acknowledgements stay attached to the mailbox that owns the workflow.

Learn more

Sender, recipient, subject, and attachment matching

Trigger replies only when the inbound message matches the sender, recipient, subject, or attachment conditions your team has approved.

Learn more

Template-driven replies with subject and reply-to control

Use raw bodies or reusable templates, set response metadata like subject and reply-to behavior, and inject variables into deterministic inbox replies.

Learn more

Reply events and trigger history

Review which rule fired, which inbound message triggered it, and how the automated reply behaved in production when a team needs an audit trail.

Learn more

Support intake with response-time expectations

Send immediate acknowledgements with clear SLA messaging while routing priority issues to staffed queues. That reduces duplicate follow-up email and sets the right expectation from the first reply.

Explore

After-hours incident and status channels

For ops mailboxes, auto replies can direct senders to incident dashboards, on-call contacts, or change windows while preserving a complete inbox audit trail.

Explore

Order, procurement, and partner reply handling

Auto replies can deliver the next step for inbound orders, supplier updates, pricing requests, or partner workflows before a human handoff, improving response speed and reducing manual triage.

Explore

Provision inboxes on demand

Create isolated addresses for users, tenants, releases, or tests without shared mailbox state.

Developer integration

Add auto-reply rules through the same inbox API

Configure acknowledgements, escalations, and after-hours replies from code so response policy stays tied to inbox ownership and routing controls.

  • Create reply rules without separate mailbox admin steps
  • Route acknowledgement flows into shared operational inboxes
  • Keep reply behavior versioned alongside your message workflows
