Email Marketing Email Marketing Growing; Spam Fading In a recent DM News article, JupiterReseach analyst David Daniels' snapshot of the 2006 email-marketing industry shows spending will grow, while the spam volume continues to fade slowly. However, email wrongly blocked by ISPs will continue to cost marketers about $1 for every $9 in an email-marketing budget: Spending on email marketing will rise 7.5% this year, from $885 million in 2005 to $950 million. Spam will decrease at a compounded annual rate of 9.4% a year through 2010 "but will remain a nuisance." False positives -- email wrongly blocked at all levels of the email delivery channel -- will cost marketers $107 million this year. HTML has nearly universal adoption among consumers: A Jupiter Research consumer survey found just 3% receive only text email. It pays to ask for backup email addresses at registration: 60% of online consumers regularly use two or more email accounts.
