Possible disadvantages

• Lack of Marketing Email Features
  Postmark is primarily designed for transactional emails and lacks many advanced features needed for marketing emails, such as list segmentation and complex automation workflows.
• Rate Limits
  Postmark imposes rate limits on sending emails, which might be a constraint for businesses with very high or bursty email volumes.
• Limited Template Customization
  While Postmark allows for the use of email templates, the customization options are more limited compared to specialized email design tools.

  Postmark's server locations are primarily based in the U.S., which may affect email delivery speeds in other regions.

• Consistent Look and Feel
  GTK strives to maintain a consistent look and feel across applications and platforms, providing a unified user experience.

Possible disadvantages

• Steep Learning Curve
  For beginners, GTK can present a steep learning curve due to its comprehensive nature and the depth of its APIs.
• Performance Overhead
  GTK applications can sometimes exhibit performance issues, especially on less powerful hardware, due to the extensive features and capabilities it includes.
• Limited Native Support on macOS
  Although GTK is cross-platform, native support and integration on macOS can be limited compared to its support on Linux and Windows.
• Heavy Dependencies
  GTK applications often require a significant amount of dependencies, which can lead to larger application sizes and more complex installation processes.
• Documentation Quality
  While GTK has extensive documentation, the quality and depth can sometimes be inconsistent, which may hinder learning and troubleshooting for developers.
