EmailCheck is an AI-powered service from Bigger Brains that helps you identify phishing and other suspicious emails. This guide explains the two ways you can use the plug-in day-to-day.
Important: AI Disclaimer
Every EmailCheck analysis is generated by AI and may be inaccurate. Treat the verdict as a second opinion, not a final ruling. If you are unsure about an email, especially one that asks for credentials, money, or unusual access, contact your IT Department, IT Support Provider, or contact us at support@emailcheck.ai before taking action.
You can analyze a suspicious email in either of two ways. The Outlook side pane is the recommended option.
Option A: Outlook (or Gmail) Side Pane
- Open the suspicious message in Outlook (desktop, web, or mobile) or Gmail.
- Click the EmailCheck add-in icon in the menu.
- Answer the SLURP quiz, identifying potential reasons you believe this email is suspicious (or not).
- Select Submit for Analysis.
- Wait a few seconds while EmailCheck analyzes the message.
- The side pane will display the risk level, its analysis of the SLURP factors, and detailed findings.
- Review the findings and summary to understand why the email was rated the way it was.
- If the message is suspicious, click Report and Block in the side pane to report or block the sender.
Please Note:
The teachable moment (SLURP quiz) is limited to 20 uses per day per user; after that, the EmailCheck tool will just return the Analysis results without the quiz.
Option B: Forward to test@emailcheck.ai
Please Note:
Forwarding the message to any email address ending in @emailcheck.ai will be accepted, not just test@emailcheck.ai. Additionally, the Forwarded-Email methodology is less accurate than the Outlook or Gmail plug-ins because it does not have access to the raw email headers
If you can't use the side pane (for example, on a device without the add-in installed), you can forward the suspect email to EmailCheck instead.
- Forward the email as an attachment, or inline, to test@emailcheck.ai.
- Within a few minutes, you will receive a reply from EmailCheck containing the risk level, a summary, and a link to the interactive quiz.
- Read the analysis and act accordingly.
Please Note:
If you don't have an active EmailCheck subscription, you will receive a short sales message instead of an analysis.
