There are several reasons why you might need to issue a new key:
Security: If you suspect that your current key has been compromised, issuing a new one can prevent unauthorized access. Integration: When connecting new third-party applications such as CRM systems or analytics tools, you may need to create a new key. Expiration: Some API keys have an expiration date, necessitating the issue of a new one. Scalability: As your email marketing efforts grow, you might need additional keys for different teams or purposes.
