    Using port forwarding services can introduce security risks if not properly configured or if the service has vulnerabilities.
  • Reliability
    As with many online services, there can be downtime or maintenance periods which may affect service availability.
  • Dependency on Third-party Service
    Relying on an external service for port forwarding can be a disadvantage if the service experiences issues or discontinues.
  • Configuration Limits
    Advanced users might find the configuration options somewhat limited compared to setting up port forwarding manually on their own networks.

Possible disadvantages

  • Limited Customization
    The platform has limited customization options compared to building a custom website or using more flexible CMS options.
  • Dependency on Platform
    Relying on Substack means depending on its policies and infrastructure, which could pose risks if the platform changes its terms or features.
  • Competition
    As more writers join Substack, it can become challenging to stand out amidst the growing competition.
  • Email Deliverability
    Writers may face issues with email deliverability, as some newsletters may end up in spam folders.
  • Payment Processing Fees
    Besides Substack's fee, payment processors like Stripe also take a percentage, further reducing net earnings for writers.
