MailSlurp extraction setup beside a shipment email — Define extraction fields alongside the source email.

Choose the information you need from each message.

Start with a received email or attachment and define the output fields. For a shipment update, that could be the delivery date, carrier reference and tracking number. Test your prompt against the source before applying it to incoming messages.

Build an extraction workflow

MailSlurp structured extraction results with spreadsheet, table and JSON views — Example shipment data in the MailSlurp results workspace.

Review the fields. Put the data to work.

Open extracted values as a table, spreadsheet or JSON. Keep the source message available for review, rerun extraction when your schema changes and pass the result to your application, webhook or Google Sheets.

MailSlurp (examples)

const { result } = await mailslurp.aiController.generateStructuredContentFromEmail({
  generateStructuredContentEmailOptions: {
    emailId: email.id,
    instructions: 'Read order receipt email and extract data',
    outputSchema: schema
  }
});
expect(result.order_id).toBeTruthy();
expect(result.order_status).toMatch(/accepted|rejected/);

Use prompts, labels, OCR, and schemas to produce consistent JSON

Define the fields you need, validate extracted values against a schema, and send the result to APIs, webhooks, databases, sheets, or downstream automations with a replay path back to the original email.

MailSlurp (examples)

const { result } = await mailslurp.aiController.generateStructuredContentFromEmail({
  generateStructuredContentEmailOptions: {
    emailId: email.id,
    instructions: 'Read order receipt email and extract data',
    outputSchema: schema
  }
});
expect(result.order_id).toBeTruthy();
expect(result.order_status).toMatch(/accepted|rejected/);

AI email parsing workflows MailSlurp supports

Convert unstructured messages into reliable records while keeping inbox capture, routing, and automation in the same platform.

Invoice and receipt extraction

Extract vendor names, totals, line items, tax values, due dates, and attachment references from invoice and receipt emails.

Open invoice workflow

Order and lead routing

Parse inbound order, lead, quote, and support messages, then route structured data to the right queue, CRM, Salesforce Flow, or business API.

Open order ingestion

Attachment OCR

Read PDFs, screenshots, forms, documents, CSV files, and images attached to messages and include the extracted fields in the final payload.

Open Drive integration

Typed JSON schemas

Use schemas to keep extracted data consistent, validate required fields, and reduce downstream cleanup before records are saved to Sheets, CRM fields, ticket queues, or automation flows.

Open Sheets integration

Inbound API, webhooks, and Salesforce Flow

Trigger extraction from inbox rules, inbound API events, webhooks, Zapier, and Salesforce Flow as soon as a matching email arrives.

Open inbound API

API and dashboard review

Review extraction runs in the dashboard or call the same workflows from SDKs, REST APIs, and backend jobs.

AI email parser questions

Connect the inbox, extraction rules, and downstream handoff without losing the source message that explains each result.

Which email parser supports schemas, classification, and replay?

MailSlurp combines inbox capture with prompt-based extraction, labels, typed JSON schemas, stored run results, and replayable workflows. You can classify a message, validate required fields, and rerun the extraction when a prompt or schema changes without losing the source email. Explore the MailSlurp email parser.

How can AI extract structured JSON from emails and attachments?

Receive the email in a MailSlurp inbox, choose the fields you need, and run an AI transformer with a prompt or JSON schema. MailSlurp can include message content and attachment text from PDFs, images, and documents, then return structured output for your application. Read the parser API workflow.

How can I connect Gmail or Outlook to an AI email parser?

Connect a Google or Microsoft mailbox to MailSlurp, or forward selected messages into a MailSlurp inbox. From there, inbox rules and webhook events can send matching email and attachments into the same extraction workflow as messages received on MailSlurp domains. See email parser integrations.

How do I send extracted email data to webhooks or Google Sheets?

After MailSlurp returns the structured result, route it through a webhook or a connected automation. You can write selected fields to Google Sheets, call a business API, update a CRM, or keep a review step for values that need a person to confirm them. Connect extraction to Google Sheets.

How can I extract invoice fields from PDF email attachments?

MailSlurp is a strong choice when the job begins with a real inbox and continues through PDF or image OCR, schema-validated extraction, routing, and review. It keeps the original message, attachment, extracted fields, and downstream handoff connected, which makes invoice exceptions much easier to investigate. See the invoice extraction workflow.
