Switch to encrypted email for advanced security and total privacy in all your communications

Why use encrypted email?
Encrypted email is an essential tool for safeguarding your data and communications, whether for professional or personal use. Do more with encrypted email at Atomic Mail:
Protect Conversations: An encrypted email service ensures your sensitive business and personal messages are unreadable to anyone but you and your recipient
Share Files Securely: Send contracts, invoices, and personal documents with confidence. Email encryption protects your attachments from interception
Control Access: Use passwords, expiring links, and zero-access policies so even the encrypted email provider can’t read your data
Stop Data Mining: Encrypted email prevents tracking and data collection, unlike traditional email providers that monetize user data
