Yep I got it to work and you were right Lonkero it needed another space. Here's the line I changed:

$r = $r +","+ SendKeys("Subject: $subject{ENTER}{ENTER}")

I just entered another {ENTER}. It works great now Except it still doesn't show anything in the "to" and "from" boxes. Actually in the "to" box it says: undisclosed-recipients:

Very interesting! This could be the next great spamming tool. Just what the world needs [Razz]
