Features and specs

What each product offers, as listed by its team.

Gblock 3 features
StackMail 5 features
  • Spy Pixel protection
    Spy pixel tracking is a sneaky technique based on adding an invisible 1x1 image, known as a "tracking pixel," to an email. When you open the email, this pixel sends information back to the sender, revealing details like when you opened it, where you were, and what device you used. All of this is done without your knowledge or consent, making it a serious privacy concern. Gblock detects and blocks tracking pixels, providing complete protection against spy pixel tracking.
  • Tracking links protection
    Link tracking involves adding custom tracking parameters to URLs, such as "?utm_source=newsletter", or embedding unique tracking codes. Some email marketing tools take this a step further by using URL shorteners to obscure the final destination, making it impossible to remove tracking parameters. Similar to spy pixels, tracking links can expose your location, device details, and other personal information. Gblock protects you from tracking links in two ways: Stripping all known tracking parameters from URLs, and using our proxy server to follow email links, masking your IP address and fully anonymizing your activity. Our proxy also caches responses, so if a tracking link is shared among multiple users, we already know the final destination and can serve it directly without accessing the tracking link. We are confident this would cover you for 99% of the cases.
  • Automated tracker detection
    Other Browser extensions rely on static lists that require frequent manual updates. But as trackers constantly evolve, this outdated approach becomes less effective. Only Gblock offers a truly intelligent solution with automated tracker detection. Instead of fixed lists, our advanced system dynamically identifies and flags new trackers in real-time. The moment Gblock encounters a new tracker, it analyzes its behavior and reports it to our server—ensuring that future emails containing the same tracker are automatically blocked.
  • Privacy-Focused
    StackMail emphasizes data privacy and security, offering encrypted email services without scanning user data for advertising purposes, appealing to privacy-conscious businesses.
  • Business-Oriented Features
    Designed specifically for businesses, it includes features like custom domain email, collaborative tools, calendars, and contact management tailored for professional use.
  • Competitive Pricing
    StackMail offers competitively priced plans compared to some larger email providers, making it accessible for small to medium-sized businesses.
  • No Ads
    Unlike some free email services, StackMail does not display ads to users, providing a cleaner and more professional email experience.
  • Custom Domain Support
    Users can easily set up email addresses with their own custom domain names, enhancing brand professionalism and consistency.

Possible disadvantages

  • Limited Brand Recognition
    As a newer or lesser-known provider compared to Google Workspace or Microsoft 365, StackMail may lack the trust and reputation that larger providers have established.
  • Fewer Third-Party Integrations
    Compared to major email service providers, StackMail may offer fewer integrations with third-party apps and services, limiting its versatility for some businesses.
  • Limited Advanced Features
    It may not offer the same breadth of advanced productivity and collaboration tools that come bundled with larger platforms like Microsoft 365 or Google Workspace.
  • Smaller User Community
    Due to a smaller user base, there may be fewer community resources, third-party tutorials, or troubleshooting forums available online.
  • Uncertain Long-Term Support
    As a smaller company, there might be concerns regarding the long-term viability, updates, and continued support of the service compared to more established providers.
