November 8, 1999, Redwood City, Calif. - ONElist (http://www.onelist.com), the leading provider of active Internet communities, today announced its new opt-in email marketing service. This permission-based service provides participating merchants the ability to reach ONElist members who explicitly request promotions of goods and services that correspond to their expressed interests. By blending opt-in marketing services with existing ONElist communities, marketers can tap into the power of consumer referrals and leverage existing relationships between ONElist community members.

ONElist has nearly 8 million registered members in more than 260,000 unique communities exchanging over 28 million emails every day. Within these free discussion communities, members inform, discover and collaborate on a wide variety of topics. According to a recent Forrester Research study, 65% of community users rate the opinions of other consumers as an important or somewhat important influence on their purchasing decisions.

"ONElist's unique approach to opt-in marketing delivers tremendous value to our advertisers," said Michael Klein, ONElist's President and CEO. "Opt-in marketing programs, when combined with influential customer word-of-mouth, have the power to dramatically improve a campaign's performance."

How it Works

Opt-in advertisers select a category of ONElist members who have indicated their desire to receive promotions of goods and services that correspond to their expressed interests, such as pets, electronics, entertainment and travel. ONElist offers these merchants exclusive access to their category of choice on a weekly basis, thereby assuring less clutter and noise that would otherwise compete with their message. Advertisers further benefit from ONElist's ever-increasing pool of fresh members, virally growing at the explosive rate of 750,000 new subscribers each month

Another key feature of ONElist's new opt-in service is the simplicity of opting out at any time. Unlike some other opt-in programs, ONElist offers its members an extremely easy way to unsubscribe from the opt-in service. ONElist's TRUSTe certification also assures members complete control over their personal data at all times.

"24/7 Media is successfully working with ONElist to offer our clients, such as Zing.com, Peapod and The Motley Fool, targeted advertising within the context of ONElist's discussion communities," said Michael Rowsom, Senior Vice President at 24/7 Media. "By adding ONElist's new opt-in service to the mix, we can now offer our clients the full spectrum of targeted online marketing and advertising options -- all within the ONElist community."
