Hello @SmaKPlastics ,
Copying older campaigns can depend on how far back in time since the original campaign was created, if the email that you are trying to copy was created using our older 2nd Generation editor; that version won’t copy anymore unfortunately. It would have to be recreated within the newer editor. If it is one of our newer 3rd Generation campaigns, you should be able to make further copies of that email.
To identify which editor that email was created from when looking at your campaigns tab the line underneath the campaign name itself it will say ‘email’ or ‘legacy email’. If it shows ‘email’ it should be eligible to copy. If that is the case, is the title you are trying to use for the new campaign one you typed in directly or are you copy and pasting the campaign name from somewhere else? If it’s being copied over try typing it directly within the campaign name field.
