Multiple layers of protection ensure you never lose an important email.
Sentinel scans email metadata for prompt injection attempts — where malicious actors embed instructions designed to manipulate AI systems. Detected emails are flagged as suspicious and never processed through the classification pipeline.
Mail-Organiser never moves, deletes, or modifies emails without your explicit approval. Every scan produces a results screen that requires your review before any action is taken. You always stay in control.
Banking, health, HMRC, and emails flagged as important are always protected — regardless of your plan. These emails are classified and shown in results but are never included in auto-move operations.
Classification is performed using metadata only — sender address, subject line, and structural signals. Email body content is never transmitted to Mail-Organiser's servers or to any AI provider. This is a hard architectural constraint, not a policy choice.
Built on Claude by Anthropic, with privacy-first architecture.
AI-powered metadata analysis classifies emails into 14 categories with high accuracy. The model learns from sender patterns and subject line signals without ever reading your email content.
Chat directly with your inbox assistant. Ask questions about your email organisation, get explanations of why emails were classified, or ask for inbox management advice. Powered by Claude.
A live score (0–100) reflecting the organisation and health of your inbox. See whether your inbox is improving over time. Green (71–100), Amber (41–70), Red (0–40). Tracks changes after every scan.
Enable monitoring to have Mail-Organiser automatically analyse incoming emails as they arrive. Protected emails are identified immediately so nothing slips through unnoticed.
A no-account-required scan that shows you the breakdown of what's in your inbox across key categories — in seconds. Share with colleagues as a lead-in to the full product.
