List all my reserved email addresses in Mailsac.

I've retrieved your reserved addresses. You have 3 active inboxes: 'test-user@mailsac.com', 'service-dev@mailsac.com', and 'alert-prod@mailsac.com'.

Fetch the plain text content of the last email sent to 'test-user@mailsac.com'.

I've retrieved the text body. The message contains a verification code: '123-456'. Would you like me to extract any other specific information?

Reserve a new private address 'automation-flow@mailsac.com'.

Successfully reserved 'automation-flow@mailsac.com'. This inbox is now private and enhanced, allowing you to capture messages exclusively.

An enhanced address is a private inbox that only you can access. Use the `reserve_new_address` tool to make an address private/enhanced.
