Folks at Newsletter and Electronic Publishers Association annual show are a fairly conservative bunch (we're talking full business suits at Sunday sessions.) But this year the buzz was the Internet. As one attendee told us, "Last year they were hiding their heads in the sand and hoping it would go away. This year they are ready to embrace it." Perhaps, but are they ready to invest real money? A new NEPA study shows the average print newsletter publisher spends under $30,000 on outsourced Web site services, which is about a tenth of what the rest of corporate America is spending. Also noted: the numbers of 100% free email newsletter publishers at the show... one, the publisher of MarketingSherpa.
