Hi there.
We sent a newsletter months ago, everything went as expected. We need to use the “view online link” some days ago, but checking it, the page showed “invalid newsletter” error text.
Checking in the backend, there are no newsletters, no stats also. Subscribers are still there.
No one deleted the sent newsletter from the backend. It’s like it disappeared.
Is it possible to understand what’s happened and to recover the previous newsletter?
Thanks in advance for your help
