Inbound email routing and webhook workflow

Route inbound email and replies to the system that owns them

MailSlurp gives each workflow a real receiving address, then turns new messages and replies into events your application can process. Use inboxes, aliases, rulesets, webhooks, and API retrieval to move customer replies, attachments, and message context into the right queue without depending on a shared mailbox.

Give every inbound event a clear next step

Attach an inbox to a NEW_EMAIL webhook and acknowledge the event as soon as your endpoint stores it. A queue or worker can then fetch the full email by ID, download attachments, and update the support, finance, order, or claims system that owns the work. The original message remains available through the inbound email API when a worker needs to retry.

Email routing rules and forwarding controls

Keep the path back to the original sender

Use a dedicated inbox when your application owns the conversation, or an alias with threads when messages are forwarded to a person who needs to reply through the same workflow. Store the MailSlurp inbox and email IDs beside your own ticket or order ID so later replies return to the correct customer record.

A practical inbound email routing flow

Start with an address that identifies the workflow, persist every arrival, and keep a recovery path when processing cannot finish on the first attempt.

Inbox-scoped routing

Create dedicated inbound addresses for a product, customer, region, or queue so the destination is clear before message parsing begins.

Open inbound API

Webhook handoff

Receive a compact event with the inbox, message, sender, recipient, subject, and attachment metadata, then hand the email ID to a worker.

Open email webhooks

Reply ownership

Keep the MailSlurp inbox and email IDs with your ticket or order so a later reply can be connected to the same customer conversation.

Rules and fallback

Use rulesets, forwarding, and monitored inboxes for messages that are blocked, unmatched, or waiting for a downstream system to recover.

Open routing controls

Attachment-aware intake

Route PDFs, receipts, claims, documents, and replies with enough context for parsing, extraction, or review workflows.

Open AI parsing

Retry-safe processing
