EmailEngine vs PHP MIME Mail Parser

EmailEngine is a self-hosted email API that connects Gmail, Microsoft 365, and IMAP mailboxes through a unified REST API. It sends webhooks when mailbox messages or state change, and can send mail through the connected account’s SMTP server or provider API. Native integrations use the Gmail API and Microsoft Graph; authentication options include managed OAuth2, service accounts for Google Workspace, Microsoft 365 app-only access, and shared or delegated mailboxes. An optional MCP server, currently in beta, lets connected AI clients search, read, file, draft, and send email with approved access. The admin interface shows sync status and queue details, with a Prometheus endpoint and Grafana dashboard for operations. EmailEngine runs on the customer’s infrastructure, uses Redis for sync metadata, and fetches message bodies on demand rather than storing them. A server and Redis using the noeviction policy are required. The annual subscription is $1,450 a year, excluding VAT where applicable, and includes developer support; each installation can start a full-functionality 14-day trial without signup or a credit card.

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.
