MailFrame

Overview

Send raw RFC 822 MIME or plain-text email-like content with a JSON Schema, and MailFrame returns validated JSON synchronously. Developers can define an inline schema without registering it first, or choose from schemas for common receipts, orders, notifications, invoices, bookings and shipping messages. The product is in limited early access, with developers onboarded in weekly batches.

MailFrame is built for integrating inbound document email into a service, not for processing documents in every form. The API currently accepts email content; PDF and image input are planned, and attachment parsing and OCR extraction are unavailable. It is one option in Email Parsing Software.

Key features

Control over parsed output

Pairing email input with a JSON Schema lets an application specify the shape of the data it expects and receive validated JSON in the same request. Inline schemas avoid a registration step, while prebuilt schemas cover Stripe and Shopify receipts or orders, PayPal and Amazon receipts, Apple App Store and Google Play receipts, GitHub notifications, invoices, travel bookings and shipping notifications. That mix should suit developers handling familiar transaction and notification emails; a less common format may call for a custom schema.

Webhook delivery

MailFrame supports signed HMAC-SHA256 webhooks with retries, delivery attempt history, a dead-letter queue and replay. These controls help teams manage failed deliveries rather than treating a parse response as the end of the workflow. Its API-first integration model is intended for downstream systems that accept webhooks.

Data and security

MailFrame says it retains raw email only for the time needed to deliver a response and provide debugging, and does not sell or share customer data. API keys are stored as hashes, so the original keys cannot be recovered from its records. SOC 2 Type II remains on the roadmap, and MailFrame says it is not yet HIPAA-eligible as a Business Associate; that makes it unsuitable where either status is a present requirement.

Pricing

The Free plan costs $0 /mo and includes 100 parse operations per month, one active schema, webhook delivery and community support, with no credit card required. It is a useful way to validate a low-volume integration, but the one-schema and 100-operation caps constrain ongoing use.

Indie costs $19 /mo for 500 parse operations, five active schemas, signed webhook delivery, email support and schema versioning. It fits a small integration that needs more than one schema and delivery signing; additional documents cost $0.038 per doc after the included quota.

Startup costs $49 /mo and raises the quota to 5,000 parse operations, with unlimited schemas, API key scoping and priority support. PDF and image input and confidence scoring are marked planned, so they should not be treated as current reasons to upgrade. Extra documents cost $0.0098 per doc.

Scale costs $149 /mo for 50,000 parse operations, unlimited schemas, cache hits included, custom webhook rate limits and an extra-document rate of $0.003 per doc. Async / Batch API is planned, and its uptime target is post-GA, so teams needing those capabilities now should not assume this tier provides them.

Enterprise has custom pricing and starts at 100k+ parse operations per month, with custom volume pricing, dedicated infrastructure, custom SLAs, an account manager and SSO / SAML. SOC 2 is on the roadmap; extra documents are priced at <$0.003 per doc.

The Free tier is described as a trial path with no credit card, but no trial length is stated. The maker also gives a monthly email limit of 500; teams should account for that alongside plan parse-operation quotas.

Platforms

MailFrame runs as an API and through the web. The API-centered approach suits software teams wiring results into their own services, rather than users seeking a standalone desktop workflow.

Who it's for

MailFrame is best suited to developers parsing email bodies into application-specific fields and delivering results to webhook-compatible services. The inline schema option is especially useful when output needs to match an application's own data model. It is a poor fit for teams that need to extract information from PDFs or images today, or require HIPAA eligibility.

Pros and cons

• Pros: Inline JSON Schemas and prebuilt formats let developers shape parsing around their application without a schema-registration step.
• Pros: Signed webhook delivery includes retries, history, dead-letter handling and replay for operational recovery.
• Pros: The free tier offers 100 parse operations monthly without a credit card, providing room to validate an integration.
• Cons: Current parsing is limited to raw MIME and plain-text email-like input; attachment, PDF and image extraction are not available now.
• Cons: Limited early access and weekly onboarding batches may be a constraint for teams that need immediate availability.
• Cons: It is not yet HIPAA-eligible as a Business Associate, and SOC 2 Type II is still on the roadmap.

Alternatives

Parserr is worth considering for users who want email parsing rules and integrations such as Zapier and Microsoft Flow, with a free plan capped at 15 emails and 10 documents per month.

Parsio Receipt OCR is a relevant alternative when receipt OCR is the priority; its free plan includes 30 credits per month and 30-day data retention.

MailParse may suit teams seeking a paid tool with an IMAP mailbox and saved templates, as well as Excel, CSV and JSON output; its Starter plan is $24.00 per month.

Parseur is another option for users who want a free plan measured in pages, with up to 20 pages monthly and one user.

DigiParser is an alternative for payslip parsing, with a paid plan starting at $14.00 per month for 100 payslips.

noima offers a small one-time free allowance of 10 documents, while its Starter tier includes 150 documents per month for €12.00 per month.

Parsli may suit someone who wants a free signup allowance of 10 pages and API access with integrations, rather than a recurring free quota.

Airparser is an alternative with a 30-day trial that includes all features and 20 credits per month.

Verdict

Choose MailFrame if you are a developer turning email bodies into schema-defined JSON and need managed, signed webhook delivery into your own service. Its combination of inline schemas and delivery-recovery controls is the strongest reason to choose it. Look elsewhere if your workflow depends on attachments, OCR, current HIPAA eligibility or immediate access outside its limited early-access batches.
