Hi there. We are about to advertise a service that is called "Pick@Home". Given our bulk email task, we would like to show the product name as the sender name in the email header. What we did: In the "Header"-tab we tried two things: Inserting a merge tag in the "Display as" field, where we use the product name depending on the language. This makes sense only, if we add some other words that are indeed language specific. (See screenshot)   Inserting the string "Pick@home" plainly in the "Display as" field. When testing (Tab "Review" and sending a test email with "Responsive previews"), SAS CI360 shows an error message:     When we change the "Display as" to only "PickHome", then the testing works flawlessly.   This raises the questions: Which special characters are allowed in the "Display as" field? Which special characters are allowed in merge tags in general? Is there any way to escape special characters in order to be able to use them? So far I have found nothing in the official SAS CI360 user documentation. Thanks for your help! ... View more
