Analysis

An editorial look at what each product does well and who it suits.

ShellNewHandler

Overall verdict

  • BulkChecker.io appears to be a bulk email/domain verification tool designed to help users validate large lists of email addresses to reduce bounce rates and improve deliverability, but as I don't have verified, up-to-date information on this specific service, I'd recommend researching current user reviews, checking recent uptime/accuracy reports, and testing with a small sample before committing to a larger plan.

Why this product is good

  • Bulk verification tools generally save time by processing large email lists quickly compared to manual checks
  • Such services typically help improve email deliverability by removing invalid or risky addresses before sending campaigns
  • May offer API access for integration into existing workflows or CRM systems
  • Often provide tiered pricing that can scale with list size, potentially cost-effective for growing needs

Recommended for

  • Email marketers needing to clean large subscriber lists before campaigns
  • Businesses looking to reduce bounce rates and protect sender reputation
  • Developers wanting API-based email validation integration
  • Users who should independently verify current pricing, accuracy rates, and customer support quality before relying on this specific service

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

  • 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
