Adobe Send does display a dialog box when the file has been sent successfully, but does not send you an email when the invitation are sent. You can, however, tell Adobe Send to notify you when someone has viewed a file that you sent via a personalized link. Is that what you're after?
I need to print the confirmation when files are sent, so it looks like it changed! Oh well, thank you!
How do you request a notification when the files are downloaded? Do you also get notification if someone only views the file?
