ShellNewHandler

Overall verdict

  • Markdown to Email is a solid, lightweight utility for converting Markdown-formatted text into HTML that renders properly in email clients, making it a useful tool for anyone who writes emails in Markdown but needs cross-client compatible output.

Why this product is good

  • Simplifies the process of converting Markdown syntax into email-safe HTML
  • Saves time compared to manually formatting emails or writing raw HTML
  • Helps ensure consistent rendering across different email clients
  • Free and accessible without requiring installation of additional software

  • Open source maintainers sending update emails to contributors
  • Anyone who drafts emails in Markdown editors and needs email-compatible output
  • Users looking for a quick, free conversion tool without signing up for complex software

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

Questions & Answers

As answered by people managing Markdown to Email and ShellNewHandler.

What makes your product unique?

Markdown to Email's answer

Most Markdown-to-HTML converters aren't built for email — they output HTML with blocks and modern CSS that Outlook and other clients simply strip out. Markdown to Email inlines every style rule automatically, so the output survives real-world email rendering rather than looking broken the moment it's pasted into an ESP. It also adds two extensions built specifically for newsletters, Markdown-syntax callout boxes and CTA buttons, that no comparable free converter offers. And unlike most "free" tools, there's no account, no upload, and no server: conversion happens entirely in the browser.

Why should a person choose your product over its competitors?

Markdown to Email's answer

Most alternatives are either generic Markdown-to-HTML converters that ignore email-specific rendering quirks, or full ESP platforms that require an account just to format one email. Markdown to Email is purpose-built for the email use case (inlined CSS, Outlook-safe table fallbacks, email-safe callouts and buttons), stays completely free with no signup wall, and never sends your content to a server, which matters if you're drafting anything before it's ready to share.

How would you describe the primary audience of your product?

Markdown to Email's answer

Independent newsletter writers and Substack/beehiiv/ConvertKit users who draft in Markdown, marketers producing HTML campaigns without a design team, and indie developers or founders sending product updates who want clean formatting without hand-writing inline CSS.

Which are the primary technologies used for building your product?

Markdown to Email's answer

Markdown to Email is built with Astro and Preact, using markdown-it for parsing, juice for CSS inlining, and DOMPurify for sanitizing the live preview Its all running 100% client-side with no backend.

  • I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
    Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
  • This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
    I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
