To send an e-mail notification using PowerShell, you can use the Send-MailMessage cmdlet. This cmdlet allows you to specify the sender, recipient, subject, and body of the e-mail, as well as any additional parameters such as the SMTP server to use for sending the e-mail.

Here’s an example of how you could use the Send-MailMessage cmdlet to send an e-mail notification:

$smtpServer = "smtp.example.com"
$to = "recipient@example.com"

$from = "sender@example.com"

$subject = "Notification from PowerShell"

$body = "This is a notification message sent from PowerShell."

Send-MailMessage -SmtpServer $smtpServer -To $to -From $from -Subject $subject -Body $body

You can also use the -Attachments parameter to include attachments in the e-mail, or the -Credential parameter to specify a username and password to use for authenticating with the SMTP server.

The Send-MailMessage cmdlet is a legacy cmdlet that was introduced in PowerShell v1. It is used to send an email message using the Simple Mail Transfer Protocol (SMTP). It is obsolete and is not recommended for use in new scripts.

Instead, you can use the .NET class System.Net.Mail.SmtpClient to send email messages. This class provides more options and better performance compared to the Send-MailMessage cmdlet.
