How TLS Encryption Works
Email Sent Over Encrypted Connection
When you send or receive an email, it travels through an encrypted TLS tunnel. Anyone trying to intercept the data in transit sees only encrypted gibberish.
Stored as Plaintext on Server
Once the email reaches CenterLeap's servers, it's stored in readable form. This allows for features like server-side search and spam filtering.
Delivered Instantly to Your Browser
When you open an email, it's sent directly to your browser over another encrypted TLS connection. No decryption processing needed, so emails load instantly.
Advantages
- Fastest performance - No client-side decryption means instant email loading
- No passwords to manage - Your login password is all you need
- Password reset is safe - All your emails remain accessible after reset
- Server-side search - Search through all emails quickly
- Better spam filtering - Server can analyze email content
Disadvantages
- Provider can read emails - CenterLeap staff could technically access content
- Vulnerable to breaches - If servers are compromised, emails are exposed
- Subject to legal requests - Emails can be provided to authorities if required
- Less privacy - Your emails are not cryptographically protected at rest
TLS is Best For
Newsletters & Marketing
Promotional emails, updates, and announcements that aren't sensitive
Transactional Emails
Order confirmations, shipping updates, password resets
Casual Communication
Day-to-day emails that don't contain sensitive information
