• Email verification: Nudge automatically checks sender domains in Gmail and Outlook, displaying a green, amber, or red banner to help you spot phishing attempts.

• Email users who receive frequent emails from unknown senders and need quick, automatic phishing detection integrated into Gmail and Outlook.
• Privacy-conscious individuals who want a security tool that works locally, stores no browsing history, and never sells data or shows ads.
