MailSlurp capabilities for email-to-webhook delivery

Turn inbound email into webhook events with programmable inboxes, payload controls, retry-safe delivery, and reliable handoff into support, finance, and operations systems.

Inbox-scoped webhook events

Attach webhooks to dedicated inboxes so new emails, replies, headers, and attachments are posted into the exact workflow that owns that address.

Learn more

Payload fields for real handlers

Capture inbox IDs, message IDs, subjects, senders, timestamps, and attachment signals so handlers can dedupe events and fetch the full email by API when needed.

Learn more

Payload schemas and test sends

Inspect webhook schemas, verify endpoint behavior, and run live test deliveries before an event consumer, parser, CRM sync, or ticketing route becomes part of a production workflow.

Learn more

Routing, parsing, and replay

Track successful and failed deliveries, replay failed posts after downstream outages, and hand events into routing or AI parser workflows without losing the original message.

Learn more

Support and case routing

Send inbound support email straight into queue consumers or case-management flows with enough metadata to classify, assign, and review exceptions quickly.

Explore

Invoice, receipt, and document intake

Trigger finance or back-office workflows from inbound attachments, vendor email, and parser output while keeping the original message available for replay.

Explore

Reply capture and order operations

Capture replies, supplier messages, and order email as webhook events so downstream systems can update records, notify owners, or trigger follow-up automation.

Explore

Parse inbound data faster

Convert messages and attachments into structured fields for downstream systems and ops queues.

TSserver.ts

// example express server that you control
const app = express();
app.use(bodyParser.json());
// receive new email webhook payload via post
app.post('/new-email-endpoint', async (request, response) => {
  // can use typescript types
  const payload = request.body as WebhookNewEmailPayload;

  // do something with with email id
  expect(payload.emailId).toBeTruthy();

  // return a 2xx status code so MailSlurp knows you received it
  return response.sendStatus(200);
});
const server = app.listen(port);

Receive MailSlurp events in your own webhook handler

Attach a webhook to the inbox, process inbound email events in your application, and keep event handling tied to the exact mailbox and API record that own the workflow.

Store the event ID and fetch the full message by API when workers need content or attachments
Keep replay and recovery paths visible when a downstream endpoint or parser fails
