The Problem

Email turns your markdown into unreadable symbols

You copy a response from ChatGPT or Claude, paste it into Gmail or Outlook, and all the formatting is gone. Hash marks, asterisks, and pipe characters instead of a professional email.

What works in Email

Honest breakdown of what transfers and what doesn't.

Headings H1–H3

Full support

Render with distinct sizing and bold weight across Gmail, Outlook, and iCloud Mail. Converted to styled paragraphs for maximum compatibility.

Bold, italic & strikethrough

Full support

All render correctly across all three major email clients. Strikethrough uses inline styles for universal support.

Tables with formatting

Full support

Render with borders, header row, and proper cell padding across all email clients. Bold, italic, and links inside cells all preserved.

Lists & nesting

Full support

Unordered, ordered, and nested lists up to 3 levels deep render properly across all email clients with correct indentation.

Code blocks

Full support

Render with gray background, Courier New monospace font, and preserved indentation. Each code block is visually separate across all clients.

Blockquotes

Full support

Render with a left gray border, padding, and italic gray text across all email clients. Significantly better than Word and OneNote.

Headings H4–H6

Partial support

Not explicitly styled. May render inconsistently or identically to body text across different email clients.

Syntax highlighting

Not supported

Code blocks render as monospace plain text only. No syntax highlighting or language labels.
