Unlock secure, private, and professional email
In 2024, data breaches are projected to cost businesses an average of $4.88 million, with email being one of the most common entry points for attackers. Proton Mail helps you safeguard confidential information, increase client trust, and ensure only the people you choose can read your messages.
Build trust and increase credibility with clients
Give every team member a professional email (for example, sales@yourdomain.com), ensuring recipients know exactly who’s contacting them. Our end-to-end encryption lets you send and receive sensitive data securely.
Customize and manage your business email
Use our intuitive admin panel to easily manage users, permissions, storage, and enforce security measures like two-factor authentication (2FA). Optimize workflows with auto-forwarding, CRM integrations, and instant replies when your team is unavailable.
Protect your data and simplify security compliance
Take a step toward meeting GDPR and HIPAA regulatory requirements with an end-to-end encrypted email platform. Add extra layers of security and manage access with password-protected emails, expiring messages, and read receipts — all backed by ISO 27001 certification and a SOC 2 Type II audit.
Stay ahead of cyber threats
Stay ahead of potential threats as Proton Mail flags and blocks malware, phishing, and man-in-the-middle attacks before they can impact your business. Enable Proton Sentinel for 24/7 account monitoring by our AI-driven threat detection platform and team of security analysts.
