Email Metadata Viewer helps users inspect raw email headers and extract key metadata and authentication signals in one structured output. You can paste complete header blocks and instantly view important fields such as sender, recipient, subject, message ID, timestamp, SPF presence, DKIM signature availability, and DMARC pass state. This solves a common troubleshooting and security workflow issue where teams need to understand email provenance quickly without manually parsing dense header text. The tool classifies risk level from authentication signals and returns normalized header key-value pairs for easier review. A functional sample input option supports immediate onboarding and testing. For advanced users, an optional AI Assistant generates a remediation and hardening plan based on missing authentication signals and header quality, while keeping AI execution user-triggered and backend-processed only.
Note: AI can make mistakes, so please double-check it.
Common questions about this tool
The tool parses raw header lines into key-value entries, extracts key summary fields, and checks SPF, DKIM, and DMARC authentication signals. It then assigns a simple risk level for quick triage.
Paste full raw headers exactly as exported from your mail client or provider. Each line should preserve header key and value format.
The must-have feature is instant authentication-signal extraction from raw headers. It removes manual parsing effort and highlights potential trust issues quickly.
Yes. It reports whether SPF and DKIM headers are present and whether DMARC pass is detected in authentication results. This helps identify basic mail-auth configuration gaps.
Analyze with AI creates an optional security and deliverability improvement plan based on detected header signals. It runs only when the user explicitly requests it.
Paste the full header block into the tool and run analysis. It highlights key fields and authentication signals so you can inspect sender trust indicators quickly. This reduces manual header parsing effort.
The viewer extracts SPF and DKIM header presence and reads DMARC pass state from authentication results. You get a summarized signal panel plus parsed header details. Use missing signals as a remediation starting point.
Start by reviewing sender, message ID, date consistency, and authentication outcomes in one view. Then inspect parsed headers for unusual relay or domain patterns. The tool helps structure your triage workflow before deeper forensic steps.
Use metadata findings to identify missing SPF, DKIM, or DMARC protections and apply configuration fixes at the domain level. Re-test headers after changes to confirm improved authentication posture. This supports cleaner delivery and trust signals.
After analyzing headers, trigger Analyze with AI to receive a prioritized hardening checklist. The plan uses detected authentication gaps and header-volume context from your run. It is optional and manually triggered.

Learn what this tool does, when to use it, and how it fits into your workflow.
Email Metadata Viewer helps security, IT, and deliverability teams inspect raw email headers and extract meaningful authentication signals fast. If you are searching for an email header analyzer tool, a way to check SPF DKIM DMARC quickly, or a workflow to review suspicious email metadata, this tool is designed for practical analysis.
You can paste full raw headers and instantly get parsed fields, authentication indicators, and a risk-level view. This cuts down manual investigation time and improves consistency in email triage workflows.
The primary function is to parse and summarize email header metadata while surfacing authentication coverage and risk. It solves the common problem of manually reading complex header blocks when investigating suspicious or failing messages.
The must-have feature is instant SPF, DKIM, and DMARC signal extraction from raw headers. This provides immediate trust context for message validation without requiring specialized parsing tools.
This supports common intents like how to read email metadata, email authentication header check, and analyze suspicious email headers.
| Output | Purpose | Action |
|---|---|---|
| Sender/recipient summary | Quick message identity snapshot | Validate basic metadata consistency |
| SPF/DKIM/DMARC signals | Authentication trust context | Identify missing protection layers |
| Risk level | Simple triage indicator | Prioritize investigation order |
| Parsed header list | Detailed inspection view | Review anomalies and relay paths |
These outputs are useful for email security triage and deliverability troubleshooting workflows.
Analyze with AI generates a practical remediation plan from your header findings. It focuses on authentication hardening and repeatable validation steps to improve trust and inbox outcomes.
The AI step is optional, backend-processed, and manually triggered by the user.
These align with Exploration Paths searches such as how to verify email authentication headers, raw email header viewer online, and dmarc pass check from message headers.
The tool analyzes pasted headers and does not connect directly to inbox providers or live SMTP logs. It is optimized for rapid interpretation and signal extraction rather than full forensic relay trace reconstruction.
For deep incident response, pair this output with mail gateway and server log analysis.
Email Metadata Viewer supports faster email trust analysis, deliverability remediation planning, and repeatable header validation workflows.
We’ll add articles and guides here soon. Check back for tips and best practices.
