Powershell to email manager of employee's expiring password

Hi, I am a powershell beginner here looking for some guidance.

I have the following script that pulls users that have accounts expiring in the next 14 days and exports them to excel with the manager property, this works great, but what I need to do now is email the managers of each user to inform them they have an employee account expiring, anyone got an idea how to accomplish this task? Thanks!
