Best Practices for Sharing Documents Securely Through Mail

Sharing Documents Securely Through Mail

In today’s interconnected world, the ability to send files via email has become indispensable. Whether it’s financial records, client contracts, or sensitive legal documents, professionals across industries depend on email for swift document exchange. However, convenience comes with a price—security risks. Data breaches, phishing attacks, and unauthorized access continue to threaten the integrity of digital communications.

At TitanFile, we believe that sharing documents doesn’t have to mean compromising on security. By understanding potential risks and adopting best practices, individuals and organizations can protect sensitive data while maintaining productivity.

This comprehensive guide explores the best practices for Send file via email, informed by past surveys and TitanFile’s experience in secure communication.


Why Security Matters When You Send Files via Email

Despite its ubiquity, email is inherently vulnerable. According to a Verizon Data Breach Investigation Report, email remains the most common vector for cyberattacks, including ransomware and phishing schemes. Furthermore, TitanFile’s 2023 security survey revealed that:

  • 64% of professionals admitted to sending sensitive files via unsecured email at least once.
  • 37% were unaware that email attachments could be intercepted during transmission.
  • 52% cited convenience as the reason for not using secure file-sharing alternatives.

These statistics highlight the urgent need for better awareness and implementation of secure practices.


Common Risks of Sending Files Through Email

When you send files via email without additional protections, you expose data to several risks:

  • Interception in Transit: Emails travel through multiple servers, making them susceptible to interception if not encrypted.
  • Unauthorized Access: If an email is accidentally sent to the wrong recipient, sensitive data could fall into the wrong hands.
  • Phishing & Malware: Emails with attachments are prime targets for malicious payloads.
  • Lack of Audit Trails: Standard email platforms don’t offer visibility into who accessed or forwarded the file.
  • Insecure Storage: Once downloaded, attachments may remain on local devices or servers without encryption.

Best Practices for Secure Document Sharing via Email

To combat these threats, professionals must adopt secure strategies when sharing documents. Below are key best practices to follow when sending files through email.


1. Use a Secure File Sharing Platform

Rather than attaching documents directly to emails, use secure file sharing solutions like TitanFile. These platforms provide end-to-end encryption, access control, and audit logs to ensure data remains protected.

Benefits of Secure Platforms:

  • End-to-end encryption during file transfer and storage
  • Two-factor authentication (2FA) for user access
  • Detailed audit trails for compliance and accountability
  • Secure client portals for document collaboration

🔐 TitanFile allows professionals to send confidential documents securely, with automatic encryption and access permissions tailored to each recipient.


2. Encrypt Files Before Sending

If you must attach files to an email, ensure they are encrypted beforehand. Use encryption software like 7-Zip or WinRAR to password-protect documents.

Encryption Tips:

  • Use AES-256 encryption standard
  • Create strong, unique passwords (12+ characters with a mix of letters, numbers, and symbols)
  • Never share passwords in the same email; use phone or a secure messaging platform

3. Avoid Sending Sensitive Information via Standard Email

Standard email is not designed for confidential communication. Refrain from sending the following through unprotected email channels:

  • Financial records
  • Legal documents
  • Personally identifiable information (PII)
  • Healthcare records (PHI)
  • Trade secrets or internal reports

Instead, use encrypted communication platforms or secure portals.


4. Enable Two-Factor Authentication (2FA)

Implementing 2FA adds an extra layer of protection when accessing email accounts or secure file sharing portals. Even if a hacker obtains a password, they won’t gain access without the second verification step.

Types of 2FA include:

  • SMS or email codes
  • Mobile authentication apps (e.g., Google Authenticator, Duo)
  • Biometric verification (fingerprint, facial recognition)

5. Verify Recipients Before Sending

Before hitting “send,” double-check the recipient’s email address. Autocomplete features in email clients can lead to sending files to the wrong person—a common but dangerous mistake.

Verification checklist:

  • Confirm the recipient’s identity through a phone call or secure channel
  • Check for lookalike domains (e.g., johndoe@yourcompany.co vs johndoe@yourcompany.com)
  • Use digital signatures or certificates to validate sender/receiver identities

6. Set Expiry Dates and Access Restrictions

Secure file-sharing services like TitanFile allow senders to control how long files remain accessible and who can view or download them.

Recommended settings:

  • File expiration dates (e.g., 7 days after sending)
  • Limit number of downloads or views
  • IP restrictions to block access from unknown locations
  • Revoke access if needed

7. Educate Team Members on Security Protocols

One of the leading causes of data breaches is human error. Organizations should provide regular training on safe digital practices, including:

  • Recognizing phishing emails
  • Using password managers
  • Secure document handling
  • Incident reporting protocols

🎓 TitanFile offers enterprise solutions that include training resources and policy guidance to help teams stay compliant and secure.


8. Use Digital Signatures for Integrity Verification

Digital signatures ensure that a file has not been altered after being sent. They verify the document’s authenticity and protect against tampering.

Benefits:

  • Guarantees file integrity
  • Builds recipient trust
  • Supports legal compliance (e.g., eIDAS, ESIGN Act)

9. Monitor Activity and Maintain Audit Trails

Knowing who accessed a file, when, and from where is essential for regulatory compliance and security auditing.

Features to monitor:

  • File access logs
  • IP address tracking
  • Time stamps of downloads
  • Notifications of file sharing or deletion

TitanFile includes built-in auditing tools to give organizations complete visibility over file exchanges.


10. Keep Software Updated

Outdated software can have unpatched security flaws that hackers exploit. Always ensure:

  • Email clients are updated
  • Antivirus and anti-malware tools are running
  • File sharing applications are patched regularly
