Okay here it is. Yes yet another send mail powershell script, but this is different!
Oh yeah, it has loads of options and yet this a GUI! yeah a GUI! Also you can send email to members listed on a CSV file and send more than one. I suppose its actually more like a mailstorm program
So copy it down, start up powershell and run .send-mail.ps1 -gui
Now fill in all the bits you like, check the verbose button and click send Mail. In the powershell console, it will show you the command line to use ;-)
Give it a go and let me know what you think. Get it from here:
