What Is Email Encryption?
Encryption scrambles email content, making it unreadable without a key. Types include:
- End-to-End: Only sender and recipient can decrypt (e.g., ProtonMail).
- Transport Layer (TLS): Secures email during transmission (e.g., Gmail).

Why Encryption Matters
Email is vulnerable to interception, with 68% of breaches involving email (Verizon, 2024). For caterers, a leaked client contract could damage reputation. Encryption ensures privacy, complies with data protection laws (e.g., GDPR), and builds trust.

Strategy 1: Combine Encryption with 2FA
Why Combine?
2FA adds an extra layer of security to encrypted email accounts.
How to Implement
- Enable 2FA on ProtonMail or Gmail.

- Catering Tip: Secure your business email to protect client data.
Why It Works
2FA and encryption together stop 99% of breaches, per a 2024 study.
Strategy 2: Secure WordPress Email
WordPress and Encryption
Your catering website’s email forms can be encrypted to protect client data.
How to Secure
- WPForms ($39/year): Encrypts form submissions.
- WP Mail SMTP (Free): Uses TLS for secure delivery.
- SSL Certificate: Ensure your site uses HTTPS.
Why It Works
Secure WordPress emails reduce breach risks by 50%, per a 2023 study.
Strategy 3: Educate on Safe Sharing
Safe Sharing Practices
Encryption is only effective if you avoid sharing sensitive data in unencrypted emails.
Tips
- Use encrypted services for sensitive data.
- Avoid sharing passwords via email.
- Verify recipients before sending.
Why It Works
Safe sharing reduces data exposure by 80%, per a 2024 study.
Measuring Encryption Success
Audit Logs: Use ProtonMail’s logs to track access.
Monitor Breaches: Check Have I Been Pwned for compromised accounts.
Test Encryption: Send test emails to verify security.
