Run program as different user - runas command

Open a command prompt console and execute the following:

C:\Users\jdoe>runas /user:loremipsum\jsmith notepad

Where loremipsum is the machine's name (or the domain name) and notepad the program you want to execute as jsmith.

The command prompt will ask for jsmith's password and if entered correctly (and if such user has sufficient permissions) the program will be executed/open.

Send email PowerShell

Create a script like the following and save it as send_email.ps1.

$from = New-Object System.Net.Mail.MailAddress "from@domain.com" 

$to = New-Object System.Net.Mail.MailAddress "jdoe@gmail.com" 

$messge = new-object system.Net.Mail.MailMessage $from, $to

$messge.IsBodyHTML = $true
$messge.Subject = "Test email to jdoe"
$messge.body = "Lorem ipsum dolor sit amet. Regards."

$smtpServer = 'localhost'
$port = '25'

$smtp = new-object Net.Mail.SmtpClient($smtpServer, $port)

$smtp.Send($messge);

Open PowerShell, go to the directory where the script was saved and execute it.

If you have permissions to execute scripts in Powershell, and the SMTP server is correctly configured, and the recipient email account exists, then you should get the email.
