DMARC Checker App
ShellNewHandler

Overall verdict

  • DMARC Checker App is a solid, free tool for validating and analyzing your domain's DMARC records, making email authentication easier to understand and troubleshoot.

Why this product is good

  • Provides a fast, free way to check whether your domain has a valid DMARC record configured
  • Helps identify misconfigurations in SPF, DKIM, and DMARC that could affect email deliverability
  • Offers clear, readable explanations of DMARC policies (none, quarantine, reject) for non-experts
  • Useful for improving email security and reducing the risk of spoofing and phishing attacks
  • Simple, accessible web-based interface requiring no software installation

Recommended for

  • Small business owners wanting to secure their email domains
  • IT administrators managing email authentication and deliverability
  • Marketers seeking to improve inbox placement and sender reputation
  • Developers and consultants configuring SPF, DKIM, and DMARC for clients
  • Anyone new to email authentication who needs an easy way to validate DMARC setup

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

  • Spammers are better at SPF, DKIM, and DMARC than everyone else
    I built a free DMARC/DKIM/SPF checker: https://dmarcchecker.app/. No usage limits, no ads—just a small footer link to one of my other projects. Made it for the exact reason you mentioned. - Source: Hacker News / over 1 year ago

  • 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
