This buyer's guide helps select the right email encrypting software by comparing SMART Encrypt, Mailvelope, Tutanota, Zohomail Encryption, Tessian Email Encryption, Broadcom Email Encryption, OpenText Message Encryption, Securiti Email Encryption, Appriver Email Encryption, and VirusTotal. The guide explains how each tool encrypts email or reduces exposure through scanning, then maps those capabilities to concrete buying decisions. It also lists common setup and workflow mistakes that show up across these tools and explains how to avoid them.
What Is Email Encrypting Software?
Email encrypting software protects email content by encrypting outbound messages and controlling how recipients can read protected content. These tools solve the problem of sending sensitive information without exposing plaintext in transit, then limiting access so unintended recipients cannot view content. Some products focus on outbound encryption with recipient portal access and message controls like SMART Encrypt. Other products extend encryption into webmail using a browser-based workflow like Mailvelope, while Tutanota provides encrypted email with built-in privacy defaults and secure sharing for hosted accounts.
Key Features to Look For
The right feature set depends on whether encryption must be enforced automatically, delivered through a secure workflow, or handled inside webmail with keys.
Recipient access control for encrypted reading
Look for encrypted delivery that pairs message protection with controlled recipient access so protected messages can be opened only by authorized users. SMART Encrypt emphasizes encrypted message delivery with recipient access control for protected reading, which reduces reliance on manual recipient behavior.
Policy-based encryption enforcement at send time
Choose tools that apply encryption decisions automatically using centralized policy rules so senders do not rely on remembering encryption steps. Broadcom Email Encryption and OpenText Message Encryption focus on policy-driven protection with recipient trust and send-time enforcement, while Tessian Email Encryption enforces outbound encryption based on sensitive content detection.
Automated encryption decisions driven by sensitive data detection
If encryption must match the sensitivity of what is being sent, select tools that detect outbound content and apply protections automatically. Tessian Email Encryption automates encryption based on outbound content and sensitivity detection, which supports consistent handling across teams with different sending patterns.
Browser-based OpenPGP encryption inside webmail
For teams that want encryption directly in compose windows, pick tools that encrypt and decrypt in the browser using OpenPGP keys. Mailvelope adds client-side OpenPGP encryption and decryption through a dedicated browser extension and supports key import, export, and organizer workflows.
Encrypted contacts and calendars with end-to-end privacy defaults
If secure email privacy must include metadata-like information and user data sharing, prioritize end-to-end encrypted services that protect contacts and calendar data. Tutanota provides end-to-end encrypted email with encrypted contacts and calendar data, which keeps those artifacts inside the same privacy model.
Centralized governance with audit trails for governed encryption
Regulated environments need governance controls that track encryption actions and message access. Securiti Email Encryption provides policy management with encryption and access controls across inbound and outbound email and includes audit trails to track encryption actions and recipient handling.
How to Choose the Right Email Encrypting Software
A practical selection framework compares how encryption is enforced, how recipients can read protected messages, and how much governance and workflow control the organization needs.
Map encryption to the required workflow moment
Decide whether encryption must be applied automatically at send time or during user compose and send actions. If the goal is centralized enforcement across users, Broadcom Email Encryption and OpenText Message Encryption apply policy-controlled message protection at send time. If the goal is automation based on what content is being sent, Tessian Email Encryption enforces outbound encryption using sensitive data detection signals.
Confirm how recipients are supposed to access protected content
Encrypted delivery must include a recipient access mechanism that matches user expectations for reading. SMART Encrypt focuses on encrypted message delivery with recipient access control and message controls managed through policy settings. Zohomail Encryption and Appriver Email Encryption also rely on external secure viewing flows for recipients, which means recipient access steps affect delivery success.
Choose the cryptography model based on key and interoperability constraints
Select a model that fits how public keys and compatibility are handled across your sender and recipient population. Mailvelope uses client-side OpenPGP encryption and decryption with key management for import, export, and organizer workflows, and outbound encryption depends on recipient public key availability. Tutanota supports OpenPGP compatibility while keeping an internal encryption model, which changes how interoperability and recipient compatibility are handled.
Evaluate governance and admin control depth for regulated reporting
For regulated communications, prioritize auditability and centralized policy control across inbound and outbound traffic. Securiti Email Encryption provides policy management with encryption and access controls plus audit trails that track encryption actions and message access. Message Encryption by OpenText also emphasizes centralized policies with routing behaviors such as blocking or encrypting outbound emails based on recipient protection behavior.
Separate encryption from link and attachment threat checking
Use threat scanning as a complementary workflow, not a replacement for encryption. VirusTotal is focused on multi-engine threat intelligence for files and URLs, and it does not provide an email encryption product that secures message contents. Tools like SMART Encrypt, Mailvelope, Tutanota, and Tessian Email Encryption provide encryption and controlled viewing that scanning alone cannot replace.
Who Needs Email Encrypting Software?

Several recurring pitfalls appear across these tools and directly affect whether encrypted email delivery works reliably in production.
Buying encryption without a working recipient access workflow
Encrypted messages still require correct recipient access setup in tools like SMART Encrypt and Zohomail Encryption. Choosing only encryption without validating how recipients open protected content leads to delivery failures and extra support work.
Assuming threat scanning replaces encryption
VirusTotal provides multi-engine URL and file scanning but it does not encrypt email contents and does not replace authentication, key management, or encryption. Teams that need protected message content should use encryption tools like Tessian Email Encryption or OpenText Message Encryption rather than relying on scanning alone.
Underestimating key availability and compatibility requirements for OpenPGP workflows
Mailvelope encryption depends on reliable recipient public key availability and compatible webmail workflows. Organizations that cannot maintain recipient key exchange should avoid relying on client-side OpenPGP-only flows and instead consider policy-based delivery tools like Broadcom Email Encryption.
Overloading strict policies without an exception strategy
OpenText Message Encryption and Securiti Email Encryption use policy rules that can block or route messages based on defined behaviors, and strict rules can frustrate edge cases. Planning exception handling and recipient compatibility early reduces friction during rollout.
