When you send an email, you probably assume it’s private, but that’s not always true. Like posting a letter, your email travels across different servers to reach its destination. If those servers don’t support proper encryption, your message could be intercepted or tampered with.
At Private Box, we care about keeping your communications secure. That’s why we’re sharing a simple tool you can use to check whether your emails are being transmitted safely.
CheckTLS.com — Test Your Email Security
CheckTLS.com is a free online tool that lets you test the security of your email connection. It checks whether your emails are encrypted in transit (via TLS) and if a domain is protected against spoofing and phishing using SPF, DKIM, and DMARC.
You can use it to:
-
Check if your domain supports secure email sending
-
Test if your recipient’s email server uses encryption
-
Identify vulnerabilities that could expose sensitive information
How secure is the privatebox.co.nz email address?
CheckTLS suggests that a Confidence Factor of 90 or above indicates that the email address is secure.
Privatebox.co.nz scores 114 meaning its very secure to email us (as long as your email sender is too!).
Why It Matters
If you’re sending important documents or personal data by email, it must be protected while in transit. Without TLS encryption, anyone intercepting the connection between servers could read your email.
If anyone requests private information, you’ll want to ensure your domain and theirs are set up correctly for secure email delivery.
