Email Tools

A complete set of free tools to inspect, analyze, and build email-related resources — from tracing suspicious headers to creating polished signatures.

Why email tooling matters

Email is one of the most technically complex parts of running a domain. Authentication mechanisms like SPF, DKIM, and DMARC protect against spoofing and phishing. Raw email headers carry a complete audit trail of every server a message passed through. Understanding these details is essential for troubleshooting delivery issues, investigating suspicious messages, and keeping your domain's sending reputation healthy. Our tools make all of this accessible without needing specialist knowledge.

Available email tools

Email Header Analyzer

Paste a raw email header to trace the sender IP, authentication results (SPF, DKIM, DMARC), routing hops, and every technical detail hidden inside your email.

EML File Viewer

Open and inspect .eml email files instantly in your browser — no extensions or email client needed. View headers, body content, and download attachments.

DMARC Report Analyzer

Upload your DMARC aggregate XML report and convert it into a clear, human-readable breakdown of SPF/DKIM results, sender IPs, and policy dispositions.

Email Signature Generator

Create a professional HTML email signature in seconds. Choose a template, customise your colours and details, preview live, then copy straight into Gmail or Outlook.

Frequently Asked Questions

What is an email header and why should I analyze it?

Every email carries a hidden header — a block of metadata prepended to the message that records every server the email passed through, the authentication checks performed along the way, and timestamps at each hop. Analyzing headers lets you verify whether an email genuinely came from the domain it claims, trace unexplained delivery delays, and identify signs of spoofing or phishing that are invisible in the normal email view.

What is SPF, DKIM, and DMARC?

These three mechanisms form the backbone of modern email authentication. SPF (Sender Policy Framework) specifies which mail servers are authorized to send email on behalf of your domain. DKIM (DomainKeys Identified Mail) attaches a cryptographic signature to outgoing mail that receiving servers use to verify the message has not been tampered with in transit. DMARC (Domain-based Message Authentication, Reporting and Conformance) ties SPF and DKIM together and defines a policy that tells receiving servers what to do when either check fails — and sends you reports when it happens.

What is a DMARC aggregate report?

DMARC aggregate reports are XML files sent by receiving mail servers to your designated reporting address. They summarize the authentication results for all emails sent from your domain over a given period, including the source IP addresses, number of messages, and whether SPF and DKIM passed or failed for each sender. Our DMARC Report Analyzer converts these raw XML files into a clear, readable layout.

What is an .eml file?

An .eml file is a saved email message stored in plain text format following the RFC 5322 standard. Most major email clients allow you to export individual messages as .eml files for archiving or sharing. Because the format is plain text, you can open it in our EML File Viewer without needing the original email client to read the headers, body, and any attached files.

Will my email data be stored or shared?

No. All of our email tools process data entirely within your browser using client-side JavaScript. Nothing you paste or upload is ever transmitted to nameindia.tech's servers. Your headers, DMARC reports, .eml files, and signature details remain completely private on your own device.

Which email clients support HTML signatures?

HTML email signatures generated by our tool are compatible with all major email clients including Gmail, Outlook (Windows and Mac), Apple Mail, Mozilla Thunderbird, and most mobile mail apps on iOS and Android. The signatures use table-based HTML layouts which render consistently across different email rendering engines.
