I have an account that requires the same AMPScript be included in the header of each email deployed.
Instead of relying on each person to add the right AMPScript when coding emails, I'd like to set up an external source, such as a content area, that contains the proper AMPScript and then call this source in each email. This would reduce the amount of coded added to each email and make changes easier as only one location would need updating instead of multiple.
The content area idea didn't appear to work. Is this possible? Does anyone have ideas on how we might do this?
