Best for encrypted email with a free plan
AtomicMail is encrypted email with a free plan that has unlimited storage and 10 aliases, and paid plans from $3 a user a month. Plus is $7 on monthly billing, and it doesn't say whether business prices assume annual billing.
Who AtomicMail is for
- Fits if you want an encrypted mailbox with no phone number
- Works for small teams that want custom-domain mail at $3 or $6 a user
Who AtomicMail is not for
- Pricey if you pay monthly, as Plus is $7 against $5 on annual billing
- Tight if you stay free: 10 aliases and no custom domain
- Watch out: the business prices don't say whether they assume annual billing
- Watch out: Atomic GPT and Atomic VPN limits on Plus and Business aren't stated
- Watch out: teams of 100 or more are sent to a contact form
Why AtomicMail 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 moneyThe free plan has unlimited storage and 10 aliases. Plus is $5 a month billed annually, a little under the middle of what email services charge.
- BFree plan and trialA free encrypted mailbox with unlimited storage, 10 aliases and no phone number needed. One person could live on it.
- BFeaturesEncryption, aliases, Hide My Email, recovery by seed phrase and custom-domain team mail. The listing shows no gap in the job.
- CEase of useNo store rating on record. You set up a recovery seed phrase and your own aliases, and a lost phrase is yours to deal with.
- BPlatforms and integrationsWeb, Windows, macOS, Linux, iPhone and Android apps. No API or integrations are listed.

Keep AtomicMail, or make your own?
Keep it
To replace AtomicMail 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 100 of the 122 other email apps we grade. It costs $36 a year.
What you could make
- Email signature: an app builder makes this well.
What you could not
- An email client: sending, receiving, threading and searching years of mail.
- Apps for macOS, Windows, Linux, iOS and Android that stay in step with each other.
- It is priced for each person, which means accounts and billing for a team.
- End-to-end encryption done properly.
- AI features, unless you pay a model provider for each request yourself.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. AtomicMail’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.
