Email remains one of the most common vectors for cyber attacks and data breaches. According to recent studies, over 90% of successful cyber attacks begin with a phishing email. As businesses and individuals increasingly rely on email for sensitive communications, implementing robust security measures is no longer optional—it's essential.

At OmyPost, we've developed advanced security features to protect your communications, but security is a shared responsibility. This guide outlines best practices that will help you maximize your email security and minimize the risk of breaches, phishing attacks, and data loss.

Implementing Strong Password Practices

• Use complex passwords: Combine uppercase and lowercase letters, numbers, and special characters.
• Avoid predictable patterns: Don't use sequential numbers, keyboard patterns (like "qwerty"), or personal information.
• Length matters: Aim for passwords that are at least 12 characters long.
• Don't reuse passwords: Use unique passwords for each account.
• Change regularly: Update your passwords every 90 days.

Two-Factor Authentication (2FA)

Two-factor authentication adds an additional layer of security by requiring something you know (your password) and something you have (typically a mobile device).

• SMS verification: Receive a code via text message when logging in.
• Authenticator apps: Use apps like Google Authenticator, Authy, or Microsoft Authenticator.
• Security keys: Physical devices like YubiKey that provide the highest level of protection.
• Biometric authentication: Use fingerprint or face recognition on supported devices.

Understanding Encryption Types

• Transport Layer Encryption: Protects emails while they're in transit between servers. Uses TLS protocol and prevents man-in-the-middle attacks.
• End-to-End Encryption: Encrypts the message content from the sender's device to the recipient's device. Only the intended recipient can read the message.
• Zero-Access Encryption: Ensures that stored messages are encrypted with keys only you control. Provides protection for messages at rest.

When to Use Encryption

• Financial information (account numbers, credit card details)
• Personal identifying information (social security numbers, birth dates)
• Healthcare information (medical records, insurance details)
• Business-sensitive data (contracts, proprietary information)
• Legal documents (contracts, agreements, litigation information)

To enable encryption for a specific message, click the lock icon in the compose window and select your preferred encryption level before sending.

Recognizing Phishing Attempts

• Urgency or threats: Messages creating a sense of urgency or threatening negative consequences.
• Impersonation: Emails claiming to be from trusted organizations but with subtle differences in the sender's address.
• Suspicious links: URLs that look similar to legitimate websites but with slight variations.
• Poor grammar or spelling: Professional organizations typically have error-free communications.
• Unusual requests: Requests for sensitive information that wouldn't normally be asked for via email.
• Mismatched URLs: The link text says one thing, but the actual destination is different (verify by hovering over links).

OmyPost's Anti-Phishing Features

• Sender verification: Visual indicators showing whether the sender has been verified.
• Link scanning: Real-time checking of links against databases of known malicious sites.
• Attachment scanning: Malware detection for all email attachments.
• Suspicious email warnings: Alerts for messages that match common phishing patterns.
• Domain spoofing protection: Detection of emails pretending to be from your own domain.

Daily Security Practices

• Verify recipients: Double-check the "To:" field before sending sensitive information.
• Use BCC appropriately: When sending to multiple recipients who don't need to see each other's addresses, use BCC.
• Log out from shared devices: Always sign out when using public computers or shared devices.
• Update regularly: Keep your email client and browser updated with the latest security patches.
• Review account activity: Periodically check your account's login history for suspicious activity.
• Clean your inbox: Regularly delete unnecessary emails containing sensitive information.

Security Settings Review

1. Go to Settings > Security
2. Verify that two-factor authentication is enabled
3. Review connected devices and remove any you no longer use
4. Check for and revoke any third-party app access you don't recognize
5. Update your recovery email and phone number
6. Ensure your default encryption settings match your security needs
