Send email using PowerShell

Windows PowerShell cmdlets has the capabilities of sending emails. We can craft email and its various components such as recipients, email body, email attachments, etc. using PS code. This feature removes manual efforts and human interventions of composing and sending emails. This opens various avenues to make your programs more dynamic as well as appealing business-wise.

$smtp = "mailservice.redduck.com"

$cc = "customer2@redduck.com"  
$from = "guardbot@redduck.com"   
$subject = "Script Run Completed - $runDateTime"
$attachmentLocation = "C:\Users\Jarvis\Desktop\TestFile.txt"

$body += "The program <b>Fantastic Powershell Program</b> has been completed successfully at <i>$runDateTime.</i><br><br>"
