In their own words
EmailEngine
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.
Mailparser
Mailparser is a cloud service that extracts structured data from recurring emails and sends it to other applications or downloadable files. Its web tool can generate parsing rules by analyzing email structure, while custom rules can read subjects, headers, bodies, sender and recipient fields, and attachments. Results can be downloaded as XLS, CSV, JSON, or XML. Users can reformat data, restructure fields, calculate sums, minimums, and maximums, and add calculated columns. Listed connections include Salesforce, Slack, QuickBooks Online, Google Sheets, and HTTP webhooks, with API access available. Supported attachments include CSV, XLSX, DOCX, PDF, and TXT; images and scanned documents are not supported. Mailparser says transfers are encrypted, passwords are one-way hashed, and staff access data only when assistance is requested. The 30-day free trial includes 30 credits. Starter monthly billing costs $29.95 a month for 250 emails and 20 inboxes.
