Atomic Mail

Atomic Mail is a privacy-focused email service for individuals who want secure personal communication across web and iOS.

Key capabilities include:

• End-to-end encryption with multiple options, including password-protected emails for recipients on any provider, plus file encryption and Atomic encryption, with transport security via TLS 1.3
• Zero-access encryption, where decryption keys stay on the user’s device, plus crypto standards including AES-256, RSA-2048, and ECIES
• Email aliases to reduce tracking and protect identity (up to 10 aliases on Free, 15 aliases on Plus)
• Unlimited storage, self-destructing messages, and seed phrase recovery for account access

Pricing: Freemium. Free plan available; Plus costs $4.99/month billed annually or $5.99/month billed monthly, and adds AI tools like Help me Write/Answer, Translator, Grammar Checker, Summarizer, Security Helper, and text-to-speech.

What makes it notable: anonymous-style signup (no phone number required), no ads or tracking, and encryption designed so the provider cannot access stored content, while still supporting encrypted email delivery to external inboxes.
