# Atomic Mail
> Atomic Mail is a free, end-to-end encrypted email service built for privacy. It uses zero-access encryption (only the user can decrypt their inbox), supports email aliases, recovers accounts via seed phrase instead of personal data, requires no phone number to sign up, runs ad-free across web, Windows, macOS, iOS, and Android, and is GDPR-compliant. Operated by AtomicMail Systems OÜ, based in Tallinn, Estonia.
Atomic Mail positions itself as a private alternative to Gmail, Outlook, Yahoo, iCloud, Proton Mail, and similar mainstream providers. The product combines blockchain-grade encryption with productivity features such as a private AI assistant (writing, summarizing, translating, grammar checking, text-to-voice) that cannot read encrypted content. The website is organized into product pages, comparison ("alternative") pages, an Academy of email-topic landing pages, and a privacy & security blog.
