About Email Header Analyzer
Free email header analyzer: trace route, check SPF, DKIM, DMARC
The Email Header Analyzer turns a raw email header into a clear report. It shows each server hop with delays, reads the SPF, DKIM and DMARC results, flags signs of spoofing or phishing, and explains the results in plain language with AI help. It runs in the browser and is free with no sign-up, for IT admins, deliverability work and anyone checking a suspicious message. Published by MailboxInsights, which also covers Outlook, Microsoft 365 and email management.
