fix: Ensure msg.send() returns boolean

Converted `msg.send()` result to a boolean in `._send_and_log_email()` for clarity and consistency.

- Updated `msg.send()` handling to return `True` for success and `False` otherwise.
- Adjusted related tests to reflect the updated behavior.
- Added new test cases to verify boolean conversion of `msg.send()` results.
