The folks at MarketingSherpa and AD:TECH published some very interesting survey results the other day. They polled the attendees of the AD:TECH conference on their preferred methods of interactive marketing. It turns out that, going in to 2005, email is their top choice. Despite all the challenges we email marketers face (filters, legislation, overflowing inboxes), email is the top choice for cost effective online marketing. This is a switch from 2004 when search engine advertising was #1. Like most everything from MarketingSherpa, this is worth a read.
