Best for encryption inside Gmail
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.
Who FlowCrypt is for
- Fits if you use Gmail and want to send encrypted messages to anyone
- Works for a company under 100 users that wants it free
Who FlowCrypt is not for
- Not for you if you use Outlook, as that version is on a waitlist
- Watch out: Workspace Key Manager is priced apart, €799 a year for 10 seats and €899 for 20
- Watch out: Google's client-side encryption needs a Workspace Enterprise Plus, Education Standard or Education Plus licence
- Tight if you're a company over 100 users, as that's sold through sales with no published price
Why FlowCrypt gets a 3.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyFree for companies with under 100 users per domain, with password-protected messages and 25MB attachments. Enterprise is quote-only.
- AFree plan and trialFree outright for domains under 100 users, with encrypted Gmail, password-protected messages, an encrypted contact page and a mobile app.
- CFeaturesEncryption 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.
- CEase of useNo store rating on record. You set up keys, and recipients without FlowCrypt open messages with a password, so there's a learning curve.
- BPlatforms and integrationsA browser extension plus iOS and Android apps, with Gmail, Google Workspace, Auth0 and OneLogin connections. No desktop app.

Keep FlowCrypt, 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.
What you could not
- An email client: sending, receiving, threading and searching years of mail.
- A real app for iOS and Android. Something home-made would be a web page.
- End-to-end encryption done properly.
- What a company asks for before it lets staff use something: single sign-on.
What this rests on. FlowCrypt’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
