Revenues from email advertising will nearly triple this year, according to a soon-to-be-released research report that highlights a little-noticed hot spot in an otherwise cold market for online advertising. Forrester Research estimates companies will spend $1.1bn (£77m)on email marketing services this year, up from $400m in 2000. Comparatively, sales of banner ads, buttons, sponsorships and display marketing will fall by 18 percent, down to $6bn this year from $7.6bn in 2000, the company predicts. A second report from research firm Gartner, expected this week, offers a more encouraging estimate of $7.9bn in overall ad sales--down marginally from $8bn last year, according to the Interactive Advertising Bureau (IAB), an industry trade group. Unlike Forrester's breakdown, Gartner's estimate includes revenue from classified advertising and email marketing. The rapid growth in email marketing has come from traditional online companies, which are increasingly choosing third parties to host their customer email promotions. Companies benefiting from the trend are not Web publishers but ad and marketing companies such as Digital Impact, DoubleClick and a raft of dot-coms that run such services. Market analysts have long predicted email would become an increasingly important marketing tool for businesses. Jupiter Media Metrix estimated in a recent report that marketers will spend more on digital marketing such as email and sweepstakes than on Web advertising by 2006, for a total of $19.3bn. The IAB, which publishes annual ad sales figures in conjunction with auditor PricewaterhouseCoopers, last month said US Web advertising sales for the first half of the year equaled $3.76bn. By that measure, if sales remained flat as some financial analysts expect, the market would be worth about $7.5bn this year. The IAB recorded a 7.8 percent decline in sales in the first half of the year from the year-ago period. Denise Garcia, analyst and author of the Web advertising report from Gartner, said a new breed of online advertisers evolving from the dot-com bust has caused growth rates to slow but not stop. Still, the market hasn't been hit as hard as traditional advertising because it's continuing to mature. It's still "a very small market, representing only 3 percent of the entire advertising industry" at $250bn annually, Garcia said. "Some of these online companies are using a slowdown in the entire advertising industry as an excuse for not making their numbers, but I think they haven't budgeted correctly or they miscalculated the size of market," Garcia said. "This is good news for the online advertising market but bad news for companies that thought that this market would continue growing at double-digit rates." As a result, analysts say that Internet ad sales will not likely gain momentum again until the overall ad industry takes a turn for the better. Next year, Forrester expects ad sales to increase by 5 percent to $6.3bn, down from earlier projections of $7bn. Jim Nail, senior analyst at Forrester and author of its report, said he doesn't expect a rebound in the market until 2003. "It depends on how you define rebound. I don't expect the market to have much more than 12 percent to 13 percent growth rates year over year from 2003 on," said Nail, adding that the rates eclipse annual growth for traditional marketing at 4 percent to 5 percent. "It's going to be a slow dawning for marketers regarding the Internet," he added. "It has more to do with psychology than technology at this point. A change in psychology will happen brand by brand, company by company, fuelled by better research and pressure from competitors." He said traditional advertisers comprised 60 percent of the market this year and are expected to equal 72 percent next year. In contrast, Gartner's Garcia says that the industry will likely see a turnaround after the second quarter of 2002. Looking forward, Gartner estimates the market will be worth $18.8bn in 2005, propelled by rich media and broadband advertising. It also reported that the landscape of advertisers will change from dot-com and technology companies to traditional advertisers such as automakers and consumer packaged goods companies by 2005. Meanwhile, Forrester predicts that in 2005 the Web advertising market will hit sales of $9.1bn. That figure is only half of the digital marketing industry comprising email and interactive TV advertising. Forrester sliced the email market into two areas: customer communications and opt-in email list services. Sales for list and newsletter advertising are expected to slightly increase from this year to next, reaching $220m in 2001 and $223m in 2002. Sales in customer communications will climb from an expected $1.1bn in 2001 to $1.8bn in 2002. "Even in the face of all that growth, many companies still run their email campaigns in-house, which we think will change over time," Nail said. "But as much demand as there is for these services, it's very competitive because it's a pretty low-barrier-to-entry business." Parsing out the numbers, Nail takes a positive view of online advertising in 2001. "I think 2001 was a successful year for online. If two-thirds of advertisers in 2000 were dot-coms, and we all know that the vast majority of that evaporated this year, the fact that the industry is down only 18 percent--not by 40 percent or 50 percent--is a miracle," he said. "By all rights it should have been a whole lot worse." Gartner's projections are based on financial reports and interviews with the top 20 sites selling online advertising, as determined by Nielsen/NetRatings from May 2000 to April 2001. It projects this group represents 80 percent of the marketplace. Gartner includes in its estimate sales of email, banners, interstitials, sponsorships and other advertising. Forrester's report is the result of interviews with 50 top marketers in the industry, as well as several dozen ad-technology and service providers.
