VBScript to send email without running Outlook

I have written an automated test that runs each night, and I would like to email the results each night once the test is finished.

In order to do this I attempted to put the following at the end of my batchfile:

Set MyApp = CreateObject("Outlook.Application")
Set MyItem = MyApp.CreateItem(0)
With MyItem
    .To = "a@a.com"
    .Subject = "Subject"
    .ReadReceiptRequested = False
    .HTMLBody = "resport"
End With
MyItem.Send

However, this is causing the email to not send because my Outlook is not open, as the test is run in the background, and I have no access to the UI.

Is there anyway to send this email without actually running outlook on the machine.

Thanks!
