Gmail is one of the world’s most popular email platforms. People rely on it for both personal communication and business transactions. Although it provides a secure setting for general messaging, Gmail doesn’t include end-to-end encryption by default. That’s where email encryption software for Gmail becomes essential. These tools add a crucial layer of security, keeping sensitive information private and shielding it from unauthorized access. With the rise of cyber threats, data breaches, and phishing attacks, encryption software is now critical for anyone using Gmail to share sensitive information.
Here are key reasons why email encryption software is essential for Gmail users:
- Data Privacy
Encryption protects sensitive information, ensuring that only intended recipients can access it. This prevents unauthorized access from hackers, cybercriminals, or even email providers. - Protection Against Phishing Attacks
Encrypted emails are harder for attackers to intercept, reducing the likelihood of phishing attempts where scammers pose as legitimate contacts. - Guarding Against Data Breaches
Encrypted emails add an extra layer of security in a data breach, making stolen emails much harder to decipher and use maliciously. - Secure Attachments and Large Files
Many encryption tools support secure file sharing, protecting attachments with sensitive information like contracts, invoices, and personal documents.
Here are ten of the best email encryption software options for Gmail to consider:
1. Proton Mail
ProtonMail secures your emails with encryption features, including end-to-end encryption, password-protected emails, and client-side encryption (CSE). End-to-end encryption ensures that only you can read your messages, protecting them throughout delivery and storage on ProtonMail’s servers. ProtonMail also lets you send password-protected emails to non-ProtonMail users for added security. These recipients receive a link to your encrypted message and must enter a password to access it.
2. Virtru
Virtru encrypts the message body and attachments before they reach Google’s servers, ensuring end-to-end privacy. Users can quickly activate encryption through a simple toggle in the compose window. Virtru also includes a data protection gateway that automates server-side security and offers granular access controls, allowing senders to disable forwarding, set expirations, add watermarks, and block downloads. Admins can create DLP rules to scan emails and automatically apply encryption and access restrictions. For recipients, Virtru provides a secure reader for safe access to attachments.
3. StartMail
StartMail provides email security tools, including TLS encryption to protect data in transit between servers and PGP encryption to ensure that only intended recipients can read messages. In addition to these protections, StartMail’s plans include privacy and organization tools like spam filters, virus scanning, contact management, and calendar integration. The platform’s standout feature is its alias functionality, which allows users to create unlimited custom aliases to keep their main address private and avoid spam.
4. SecureMyEmail
SecureMyEmail offers strong email encryption for various email services, including Gmail, Outlook, Exchange, Yahoo Mail, and Hotmail. It’s easy to set up and doesn’t require technical expertise or PGP key knowledge. SecureMyEmail wraps emails in an encrypted “envelope,” ensuring only the recipient can read the message and attachments—keeping them secure even from the email provider, ISP, and SecureMyEmail itself.
5. Mailfence
This email service supports OpenPGP encryption, making it compatible with many third-party email platforms. However, email addresses and subject lines remain unencrypted, leaving them vulnerable to being read by others. Mailfence features a user-friendly and appealing interface, along with advanced functionalities. Users can easily import contacts and messages because Mailfence supports SMTP, POP, IMAP, and Exchange ActiveSync. You can access this email service through a browser or via a progressive web app available for iOS and Android devices.

Tuta, formerly Tutanota, is an email encryption software compatible with Gmail. It provides end-to-end encryption for emails between users, utilizing a combination of symmetric and asymmetric algorithms to secure communications. Tuta can send notifications to external recipients who do not use the service. The platform offers a free email app that includes encrypted contacts and calendar features, along with business plans that support user management and administrative levels.
7. Mailbox.org
Mailbox.org provides several encryption features to enhance its email service. Users can easily encrypt their emails with OpenPGP by clicking the padlock icon in the upper-right corner of the composer window. The system will automatically search for valid OpenPGP keys associated with the recipient’s email address and display a symbol next to it if a key is found. Additionally, the Mailbox.org webmail client conducts a TLS check before sending emails, ensuring they are transmitted over a secure SSL/TLS-encrypted connection.
