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.
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.
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.
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.
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.
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.
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.
Provision inboxes on demand
Create isolated addresses for users, tenants, releases, or tests without shared mailbox state.
