How To Evaluate Your Error State UX Agency?

During our benchmarking, we identified three key issues that often arise while choosing the best error state design agencies:

  • Most teams overlook empty/error states entirely, leaving them as default system messages.

  • Few agencies build systems for scalability—so error messaging feels inconsistent across the product.

  • Many designs fail to offer helpful context, recovery options, or empathy during failure.
