Subject: Account Suspension Appeal - [your email]

Hello Anthropic Support Team,

I am writing to appeal the suspension of my Anthropic account 
([your email]).

I believe my account may have been incorrectly flagged due to 
[briefly explain the situation, e.g., "network configuration 
changes" / "testing from a different location"].

I would appreciate if you could review my account status and 
provide guidance on how to restore access.

Thank you for your time.

Best regards,
[Your Name]
