"Prevent Accidental Data Leaks and Phishing Risks in Gmail with Smart External Alerts Have you ever accidentally sent a confidential email or internal information outside your company — or received a suspicious message from an unknown external sender? A single oversight can lead to data exposure, compliance issues, or even phishing attacks. External Email Alert acts as your intelligent, built-in safety shield within Gmail—helping you identify external communication risks before you act. Our extension automatically checks email domains while you compose outgoing emails and while you read incoming emails. If an address from outside your organization’s domain is detected in the From, To, Cc, or Bcc fields, it displays a clear, unmissable alert so you can stay alert and make informed decisions. Key Features ⚠️ Automatic External Detection Instantly flags any recipient or sender that does not belong to your internal domain—both incoming and outgoing emails. ✉️ Protect Against Mis-send & Phishing Risks Alerts when you might unintentionally share sensitive data—or when receiving external emails that may be risky. 🎨 Seamless Gmail Integration Alert banners blend perfectly into the Gmail interface without interrupting your workflow. ⚙️ User Preferences Custom settings stored locally for a tailored, consistent experience every time. 🔒 Secure & Private We never store, transmit, or read your email content.
