I know what to do!

I have an email address that old people often often assume is their address, so I often get confirmation emails for medical procedures that under HIPAA should not be sent unless unless the address has been verified.

The easiest way to stop them is to email the company any let them know they just leaked personal health information and that they should verify addresses. That gets things fixed real quick.

Well, Anthropic touts itself as HIPAA compliant, so if you can contact Anthropic's legal department, let them know that not verifying email addresses could lead to a HIPAA violation. In the overwhelming likelihood that they've made it difficult to contact their legal department, you can file a HIPAA complaint with the NHS (https://www.hhs.gov/hipaa/filing-a-complaint/index.html) and let them know that Anthropic claims to be HIPAA compliant but does not verify the ownership of email addresses before assigning them to a client's account, which may contain personal health information, which could be leaked en masse.

Another option is to file a charge back with the credit card company, and let them know that due to Anthropic's web page not complying with the ADA's WCAG, you are unable to access your account.
