Thank you Allison,
I don't know why it was posted 3 times, but I swear I didn't hit the Submit button more than once! Maybe some autosave function in IE (does it even have that?).
Great knowing that there is a system in place that filters the recipients list based on the security setup, but wouldn't it make more sense to use the Owner of the Email Send record, rather than the user who created it? I mean, it happens that I create an Email Send record for someone else to work on. I would make that person the Owner since it's his Email. And what will happen with clones? Don't they have the ClickDimensions service user in the Created By field? The service user normally has the sysadmin role, so it can see all contacts. Won't that Email Send not be sent to all contacts on the list then, even the ones that the Owner is not supposed to see?
Thanks
Joris
