MailFrame vs PHP MIME Mail Parser

MailFrame is a developer-first API that turns raw email into JSON validated against a schema. A request can include raw RFC 822 MIME or plain-text email-like input and a JSON Schema, with validated JSON returned synchronously. Developers can provide an inline schema without registering or choose from prebuilt schemas covering Stripe and Shopify receipts or orders, PayPal, Amazon, Apple App Store and Google Play receipts, GitHub notifications, invoices, travel bookings, and shipping notifications. Signed HMAC-SHA256 webhook delivery supports retries, attempt history, a dead-letter queue, and replay, for downstream systems that accept webhooks. The current API accepts raw MIME and plain-text input; PDF and image parsing are planned, not currently supported. MailFrame says it retains email content only as long as needed for delivery and debugging, does not sell or share customer data, and stores API keys in hashed form. The service is in limited early access, onboarding developers in weekly batches. The Free plan provides 100 parse operations per month without a credit card; paid plans start at $19 per month. SOC 2 Type II is on the roadmap, and MailFrame says it is not yet HIPAA-eligible as a Business Associate.

PHP MIME Mail Parser is a PHP library for reading MIME email, built around the mailparse extension. It can handle mail forwarded from Postfix, read.eml messages, support webmail creation, and store email information in a database. Messages may be provided by file path, raw MIME text, PHP file resource, or stream such as stdin. The parser returns headers as raw text or an array with character-set conversion, and can extract addresses and subject. For message content, it retrieves text and HTML bodies, including HTML with embedded content such as images. It can list and save attachments, include or omit inline attachments, and apply a strategy for duplicate filenames. Installation is recommended through Composer as php-mime-mail-parser/php-mime-mail-parser. It requires PHP 8.2 or later and the mailparse extension; listed supported PHP versions are 8.2, 8.3, 8.4, and 8.5. The library supports Linux, macOS, Windows, and self-hosted use, and is released under the MIT license. Pricing is free.
