At present Eloqua only allows very limited customization to Form notification emails. It should have flexibility to delete fields which customer sees as irrelevant.
The idea is under consideration by Oracle
This would be great, being able to give the salesperson (the usual recipient of Notification Emails in our world) a little more context behind the notification they're getting, would be helpful.
I get this question quite often, the only way is to customize the header which is way too Limiting. There is already the option to select a notification template so why not add more options to customize it further
