Radix evaluated 145 e-commerce platforms across 16 categories, including website builders, payment providers, email services, and social media management tools. The study tested whether email addresses using new short TLDs (three characters or fewer, for example, .fun and .uno), new long TLDs (four characters or more, for example, .online and .website), and Internationalized Domain Names were accepted during standard sign-up processes.

Key Findings:  

1) 14 out of 16 e-commerce platform categories showed full acceptance of new short and new long TLDs during user sign-ups.  

2) New short and new long TLDs achieved a combined acceptance rate of 98.6% across all platforms tested, indicating strong overall support for these domain types in sign-up workflows.  

3) IDN-based email addresses had an average acceptance rate of 39.31% across all platforms tested, indicating significantly lower support compared to new short and new long TLDs.
