EmailEngine vs noima

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.

noima extracts requested information from emails, PDFs, scans, and spreadsheets, returning it in structured formats. Users can describe extraction needs in plain language or have AI create classifiers and extractors from sample documents. An AI splitter can divide multi-document PDFs into sections or treat each page separately. Inputs arrive through a workspace email inbox, file upload, or API; supported formats include PDF, EML, HTML, TXT, JPG, PNG, BMP, DOCX, XLSX, XLS, CSV, and Markdown, with a 20 MB limit per file. Results can be exported as Excel, CSV, JSON, or Markdown, or retrieved by API. Small, Balanced, and Pro models use one, two, and three credits per document, respectively. Quotas are shared across an account’s workspaces, and processing stops when the allowance runs out. Failed documents are retried automatically without extra document charges for retries, though an ultimately failed upload still uses one document. The maker says data is hosted in the EU and handled in line with GDPR. Plans include a free one-time allowance and paid tiers starting at €12/mo.
