Early Access 300+ developers joined Built for production — Schema validation • Confidence scoring (planned) • Signed webhooks

Your inbox becomes an API

Stop maintaining brittle extraction pipelines. MailFrame turns raw email into typed, schema-validated JSON — returned synchronously via a single API call. One API call. One schema. Zero regex. (PDF, image & inbox forwarding planned.)

The Problem

Ingesting documents today is a maintenance nightmare

Every team building document ingestion ends up maintaining the same fragile infrastructure.

Regex Spaghetti

Hand-crafted regex patterns that break the moment Stripe changes their email template. You maintain parsers, not products.

Brittle GPT Wrappers

A Python script that calls GPT with a prompt. No validation, no retries, no monitoring. Breaks silently in production.

Zapier Chains

Multi-step Zaps held together with duct tape. No error handling, no observability, no SLA. Good for prototypes, dangerous in production.

Manual Retries

Failed parse? Manually re-run. No DLQ, no replay, no alerting. Incident response is a developer SSH-ing into a box.

How It Works

POST today, forward soon

Direct POST /v1/parse is how you parse today. Inbox forwarding is on the roadmap — both produce the same typed, validated JSON.

Server-to-server

Direct API

Send raw email (MIME) plus JSON Schema via POST /v1/parse and get typed JSON back synchronously. 

import { MailFrame } from "...";
const mf = new MailFrame({ apiKey: "..." });
const result = await mf.parse({
  raw_mime: "From: receipt@stripe.com\n...",
  schema_id: "stripe-receipt",
});
console.log(result.data);
Response 
{
  "receipt_id": "pi_abc123",
  "amount_cents": 2999,
  "currency": "usd",
  "paid_at": "2026-05-21T17:30:00Z",
  "customer_email": "user@example.com",
  "card_last4": "4242",
  "card_brand": "visa"
}
Roadmap · Forward-and-forget

Inbox Direct (planned)

On the roadmap: a unique parse@mailframe.ai inbox. Forward any email and MailFrame will extract and deliver JSON to your webhook — here's the planned flow. Until it ships, POST the raw MIME to /v1/parse. 

# 1. Get your inbox address
#    parse@mailframe.ai

# 2. Create filter in Gmail
 Match: from:stripe.com
 Do this: Forward to parse@mailframe.ai

# 3. MailFrame parses the email
#    JSON returned via API

Try it yourself — runs in your browser, no signup. Paste any receipt, invoice, or order email below.

Input — Raw Email

Output — Structured JSON

Press "Extract JSON" to see results

This preview runs entirely in your browser. It uses simple pattern-matching and never sends your text anywhere — so it only reports fields it can actually find. The production MailFrame API does more: LLM extraction against your own JSON schema, returning typed JSON via POST /v1/parse or signed webhook delivery with retries, attempt history, dead-letter, and replay.

MailFrame is built for developers who need ingestion that doesn't silently break at 2 AM.

Extraction Trace

Resilience inproduction

Extraction is easy. Handling model timeouts, schema mismatches, and malformed input at scale is where infrastructure matters.
