Marco
Marco is a privacy-first, offline-first email client for people who don't want AI writing or reading their email.
The Problem
Email is meant to carry a person's own thoughts, but AI features in mainstream clients are turning it into machine-generated content. Users of Gmail and Outlook face clutter, ads, and increasingly polished but generic AI drafts, rewrites, and summaries that process private conversations on third-party servers. A testimonial describes Gmail as ad-cluttered and Outlook as 'an unusable mess.' As software can generate endless mail, users lose attention and meaning, and their private words get processed by AI systems that were never part of the original conversation.
The Solution
Marco is an email client that deliberately excludes AI drafting, rewriting, summarizing, or replying, keeping email as a conversation between people. It supports Gmail, Outlook, Yahoo Mail, iCloud, and any IMAP provider, unifying multiple accounts into a single inbox. The product is offline-first, syncing emails locally so users can read, search, compose, and organize mail without internet access, with changes syncing automatically on reconnect. It is end-to-end encrypted at rest and in transit, does not scan emails for ads or tracking, and runs on macOS, iOS, and web with cross-platform sync. Marco is free forever with no credit card required, offering unlimited accounts, offline access, smart search, and custom labels and filters, with a 'Pro' tier for power users listed as coming soon.
