"Despite the assault e-mail marketing endures from spam and phishing, even with the drag on delivery rates imposed by the filters, and regardless of the sheer e-mail overload in most people's inboxes, 71% of US online advertisers used e-mail marketing in 2004," says Mr. Hallerman. "That's only six points less than the number of respondents using paid search — the current interactive marketing favorite — and 12% of advertisers plan to start e-mail campaigns in 2005."
