I can understand how this is very frustrating. Can you help with some additional information on what is happening?
- Are you creating and saving an email and then coming back to it or are you losing the email in the middle of creation?
- Are you seeing any error messages?
- Are you creating an email or another type of campaign?
- What browser/version are you working in?
Also, if you have the name of one campaign that isn't showing please let us know so we can look internally.
