sillitoe I encountered a similar problem to that described in this post but with version 7.5.7: https://forum.acymailing.com/d/2075-saving-error I was unable to save an email. It transpired that it was because no list was assigned to the email. After I assigned a list, I was able to save it. However, this does not seem normal, because a new email would not yet have a list assigned.
