Mailinfo Best Practices: Tips to Organize Email Like a Pro

How Mailinfo Improves Email Security and Privacy

Email remains a primary attack vector for cybercriminals and a common place where sensitive information is exchanged. Mailinfo addresses these risks with a layered approach that combines strong encryption, smart filtering, and privacy-forward design choices. Below are the key ways Mailinfo improves email security and protects user privacy.

1. End-to-end encryption for sensitive messages

Mailinfo uses end-to-end encryption (E2EE) to ensure that email contents are readable only by the sender and intended recipient. With E2EE, message bodies and attachments are encrypted on the sender’s device and decrypted only on the recipient’s device, preventing interception or reading by mail servers or third parties.

2. Strong transport security (TLS)

All connections between Mailinfo clients and servers use modern Transport Layer Security (TLS) with up-to-date cipher suites to protect messages in transit. This prevents man-in-the-middle attacks during delivery and synchronisation.

3. Zero-access architecture for metadata minimization

Mailinfo minimizes stored metadata and employs a zero-access design where possible, meaning server operators cannot read message contents. Metadata retention is limited to what’s necessary for basic delivery and functionality, and sensitive headers are obfuscated or hashed.

4. Advanced spam and phishing protection

Mailinfo integrates multi-layered spam and phishing detection:

• Sender authentication using SPF, DKIM, and DMARC to verify senders and reduce spoofing.
• Machine-learning models and heuristic filters to detect suspicious patterns, malicious links, and social-engineering attempts.
• URL sandboxing and link rewriting that warn users or open links in a protected environment.

5. Attachment scanning and sandboxing

Attachments are scanned for malware using signature-based engines and behavior-based sandboxing. Potentially dangerous file types are either blocked by default or opened in isolated viewers, preventing malicious code execution on user devices.

6. Granular privacy controls and selective sharing

Users can control what information is shared with
