Email Analyzer

Every Display Name, decoded. Outlook shows names; attackers pick names. Email Analyzer shows the real sender and the actual address each message was sent to, checks SPF, DKIM and DMARC, flags the tricks phishing relies on, and shows where every link really goes.

Built for organizations on Microsoft 365, from small teams to the largest enterprises. IT and security teams, help desks and managed service providers use it to triage suspicious mail in seconds, and every employee can check a message before they click. Admins deploy it to everyone from the Microsoft 365 admin center, with nothing to install on devices.

No telemetry or data collection. Analysis runs on your device. No account, no sign-in, no tracking and no ads. The add-in reads only the message you open and never sends its content, addresses or results to zuykn or anyone else.

• The real sender and the actual address it was sent to, behind every Display Name
• SPF, DKIM, DMARC and Microsoft CompAuth at a glance, from your own mail server's results
• Look-alike domains, reply-to swaps, disguised links and risky attachments, flagged
• Where every link really goes, with Safe Links unwrapped
• Every delivery step in order, with exact times and the gap between each
• Accurate behind inline security gateways such as Check Point, so legitimate mail isn't flagged as forged
• Microsoft's spam verdict in plain English
• One-click copy for any address, a whole To or Cc list, any section, the raw headers or a full report for a ticket
• Follows Outlook's light or dark theme

Use Cases

• Confirm who really sent an invoice, payment change or password reset before acting on it
• See who a message was actually sent to, even when you were BCC'd or reached through a distribution list
• Triage user-reported phishing in seconds, then paste a full report into the ticket
• Check SPF, DKIM and DMARC results while troubleshooting mail delivery
• Keep legitimate mail behind gateways such as Check Point from being flagged as forged
