How It Works

1

Export your email as .eml or .msg

In Gmail: open the email, click the three-dot menu → Download message (.eml). In Outlook: File → Save As → .msg. In Apple Mail: drag the email to your desktop. Then upload the file here.

2

Header and body extraction

Our converter extracts the From, To, CC, Subject, and Date headers as structured Markdown metadata, followed by the full email body including any quoted reply chain — formatted as readable, flowing Markdown text.

3

Analyze or archive with AI

Paste the Markdown into ChatGPT or Claude to summarize long threads, extract action items, draft replies, or identify key decisions buried in lengthy email exchanges.

Who Uses This

Real workflows from real people who convert emails to Markdown.

Executives & Managers

Convert lengthy email chains to Markdown before feeding to AI for thread summarization. Get a 3-bullet summary of a 40-message thread in 10 seconds — including who agreed to what and by when.

Customer Success & Support Teams

Convert customer email threads to Markdown for AI-powered insight extraction. Ask Claude to identify complaint patterns, recurring issues, or escalation triggers across a batch of support tickets.

Legal & Compliance Teams

Convert email evidence and regulatory correspondence to Markdown for AI-assisted review. Search for specific parties, dates, or commitments across large email collections without manual reading.

Researchers & Journalists

Convert interview emails and source correspondence to Markdown for systematic analysis. Extract quotes, commitments, and fact claims from email threads as part of research documentation.

Why Convert Emails to Markdown for AI?

Email threads are notoriously difficult to analyze at scale. A single email chain with 15 replies can span 8,000+ words of repeated quoted text, HTML formatting tags, signature blocks, legal disclaimers, and forwarded message headers. The actual new content in each reply might be 50 words, buried under 500 words of re-quoted previous messages. Pasting this directly into an AI tool produces analysis dominated by the repetition rather than the substance.

HTML-formatted emails are even more problematic. Rich-text emails contain the same tag bloat as web pages — bold and italic markup, inline styles, background colors, table layouts for visual formatting — none of which carries semantic meaning for AI analysis. The model spends tokens processing `<td style='padding:10px;'>` instead of reading your actual message.

Email to Markdown conversion strips all of this. Reply chains are linearized with clear 'From:' and 'Date:' markers on each reply. HTML formatting is converted to lightweight Markdown equivalents. Signature blocks and legal disclaimers are typically filtered out. What remains is the actual conversation — structured, readable, and AI-ready.

For knowledge workers who live in email, this workflow is transformative. Convert an email thread to Markdown, paste to Claude with 'summarize this thread and extract all action items with owners and deadlines', and a 20-minute reading task becomes a 30-second AI-assisted task. For legal discovery, support ticket analysis, or research correspondence, the same principle scales to hundreds of emails with proper tooling built around this conversion step.
