## Key features

- **Encryption:** Messages between Atomic users use ECIES encryption; mail to other providers can be encrypted with a password or as a file. The vendor says it cannot read encrypted content.
- **Aliases and Hide My Email:** Free accounts get 10 aliases. Plus and the Business plans add Hide My Email addresses for sign-ups and newsletters.
- **Private sign-up and recovery:** Accounts can be created without a phone number or a secondary email, and recovery uses a seed phrase.
- **AI writing suite on Plus:** Plus includes a writing assistant, grammar checker, summarizer, translator, security helper and read-aloud.
- **Custom-domain team email:** Business plans give each user an address on the company's own domain, with end-to-end encryption and per-user storage.

## Good for

- People who want encrypted email without giving a phone number
- Small teams that want encrypted mail on their own domain
- Users who want many aliases to separate sign-ups

- Teams of 100 or more seats are sent to a contact form for an Enterprise plan.
- Atomic GPT and Atomic VPN are listed as included on Plus and Business plans; their limits are not stated.

- **Value for money: A.** The 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.

- **Features: B.** Encryption, aliases, Hide My Email, recovery by seed phrase and custom-domain team mail. The listing shows no gap in the job.
- **Ease of use: C.** No store rating on record. You set up a recovery seed phrase and your own aliases, and a lost phrase is yours to deal with.

## Keep it, 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.

- You could make: Email signature: an app builder makes this well.
- You could not: An email client: sending, receiving, threading and searching years of mail.
- You could not: Apps for macOS, Windows, Linux, iOS and Android that stay in step with each other.
- You could not: It is priced for each person, which means accounts and billing for a team.
- You could not: End-to-end encryption done properly.
- You could not: AI features, unless you pay a model provider for each request yourself.
- You could not: The depth: we grade its features B, which means it covers the whole job.
