In Microsoft Outlook, how do you make a rule to send an alert to another email address from a specific sender?

Question

In Microsoft Outlook, I am looking for a rule that would send only an alert (no content nor subject of email) to a separate email address from a specific sender.

For example:

1. Email A1: Sends Email
2. Email B1: Receives Email
3. Email C1: Receives Alert

A1 sends an email to B1.

Once the email is received by B1, the Outlook rule sends an alert to C1 letting them know that the sender sent an email.

Thank you!
