Inbound Email Security is the next generation of email protection included with Paubox Email Suite Plus and Premium. It uses advanced AI to safeguard your inbox from spam, phishing, and other malicious emails.
How Inbound Email Security works
Inbound Email Security is powered by generative AI, which goes beyond traditional static rules or keyword filtering. Instead, it learns and adapts to your organization’s unique email environment:
-
Analyzes tone and intent: Understands whether an email’s language or intent matches normal communication patterns
-
Evaluates sender behavior: Detects unusual activity, such as spoofed addresses or suspicious sending patterns
-
Identifies anomalies: Compares messages against historical patterns to flag potential risks
-
Learns over time: Continuously improves accuracy by adapting to new threats and your organization’s evolving email traffic
What you need to do
Inbound Email Security is automatically included with Paubox Email Suite Plus and Premium.
-
No additional setup is required
-
With any change to email filtering, it's always a good idea to keep an eye on your quarantine
-
The AI will learn over time - If there is mail in your quarantine that you want, "release and allow" will prevent mail from that sender/domain from being caught again
Tips for helping AI learn
Inbound Email Security AI learns as it gets more data. You might initially see more false positive volume in quarantine, but that will quickly change as it learns what is legitimate. Here are tips for helping AI learn:
- Release and allow legitimate mail in quarantine
- Set up whitelist rules for trusted senders
- Find out why the AI placed an email in quarantine in the message headers
- Set up quarantine reports for users to manage their quarantined messages
Find out why an email was quarantined
Click on an email in quarantine, then view Original Message. In the Header tab, you’ll see an explanation as to why Inbound Email Security classified the email a certain way as well as a confidence rating (how confident that it was accurately classified).
Benefits of AI-powered security
-
Stronger protection: Generative AI is better at detecting malicious email because it goes beyond static rulesets. It understands what “normal” email looks like (sender patterns, tone, and intent) and flags anything that doesn’t belong.
-
Less manual oversight: Spend less time fine-tuning rules, reviewing quarantined emails, and chasing down false positives. It’s built to be “set it and forget it” with the AI continuously improving as it sees more data. The result: stronger security with less day-to-day maintenance.
-
HIPAA compliant by design: Paubox has always been built for healthcare. Inbound Email Security has been architected with HIPAA compliance at its core. Patient data is safe and never shared with 3rd parties.
