FlowCrypt adds encryption to Gmail, with password-protected messages to anyone, and it's free for companies under 100 users. It works with Gmail only, and the Outlook version is on a waitlist. Workspace Key Manager is priced apart in euros. - **Value for money: A.** Free for companies with under 100 users per domain, with password-protected messages and 25MB attachments. Enterprise is quote-only. - **Free plan and trial: A.** Free outright for domains under 100 users, with encrypted Gmail, password-protected messages, an encrypted contact page and a mobile app. - **Features: C.** Encryption inside Gmail, password-protected messages, an encrypted contact page, mobile apps and enterprise administration. It does that job fully, but it's a smaller job, and it covers Gmail only. - **Ease of use: C.** No store rating on record. You set up keys, and recipients without FlowCrypt open messages with a password, so there's a learning curve. - **Platforms and integrations: B.** A browser extension plus iOS and Android apps, with Gmail, Google Workspace, Auth0 and OneLogin connections. No desktop app. These are ToolGPA's own grades. Graded from this listing, whose facts were read from FlowCrypt's own pages on 12 November 2026.

The category's chart of price against score: https://toolgpa.com/charts/email ## Keep it, or make your own? **Keep it.** To replace FlowCrypt you would be making an email client: sending, receiving, threading and searching years of mail. That is not a weekend's work, with an AI app builder or without one. It is one of the better ones too: its GPA of 3.0 is higher than 55 of the 70 other email apps we grade. - You could not: An email client: sending, receiving, threading and searching years of mail. - You could not: A real app for iOS and Android. Something home-made would be a web page. - You could not: End-to-end encryption done properly. - You could not: What a company asks for before it lets staff use something: single sign-on.
