When a subscriber is using Hotmail, Yahoo!Mail or TDC Webmail, and marks your newsletter as "Junk", Ubivox receives a notification stating that a subscriber has "complained" about receiving the newsletter. The subscriber is then, automatically, suspended from the list. This guide elaborates complaints and how they are handled in Ubivox.
Ubivox collects detailed statistics from you newsletter that enables you to, subsequently, analyze the results from the specific newsletter. The guide elaborates what the different statistical data functions mean.
