Technology / Email / Pass-Along: An email recipient who got your message via forwarding from a subscriber. (Some emails offer 'forward to a friend' in the creative, but the vast majority of pass-alongs happen using email clients, and not that tech.) Pass-alongs can affect the formatting of the email, often stripping off HTML. Also known as viral.
Business / Internet Marketing / Pass-Along Rate: The percentage of people who pass on a message or file. MORE
