Extension summary

This extension will run automatically when you are in your regular google mail web interface (mail.google.com).

It will read email addresses in the "TO", "CC" and "BCC" fields and check those emails against our crowdsourced database. If an email has been flagged as "Risky", a colored box will appear next to the email to indicate the level of risk.

You can also click on the box to find details on the email and flag an email yourself.

The idea is that you'll know if an email address is probably a risk to interact with because others have flagged that email as risky.

Upcoming features:

  • Integrate with new Google Inbox
  • Updated look and feel
  • Optionally scan emails you've already sent for risk factors
  • Safari, Firefox extensions
  • Outlook, Thunderbird and other extensions
