How to automate sending periodic email using macOS

I want to automate sending email with same message & different send date (every week) to one address & copy to sender - sample below. Message must be sent during office hours ( 9am - 5pm Tue - Fri) to assure macOS is running.

Date: [current date - once a week]
To: Local_Company@...
CC: Process_User@...
From: Process_User@...

Local process has been started. Please acknowledge.

Thank you
