That nearly half of e-mail subscribers purchases are influenced in their decision making by e-mail? That’s a qualified summary, conditional on the kind of content received and the relevance of the content. But it’s too large a percentage to dismiss as irrelevant, regardless of the actual number cited.

Keep in mind thats a measurement of subscribers, not just receivers who may be on a forward or broadcast list. But regardless of what’s parsed, one major conclusion is that ignoring your web visitors by not capturing data and sign-up info and then following up with rich content media delivery may be sacrificing a significant revenue stream.
