Forwards..?

Forwards..?

Hi,

In Campaigns where the campaign statistics are shown, there are seven headers:-

Recipients, Opened, Unopened, Clicked, Unsubscribed, Marked Spam and Forwards.

I am curious about Forwards. Is it supposed to show when an email has been forwarded? It never shows anything.

I have one customer I know always forwards my emails, but nothing appears here. Ever.
