Advertisers may soon face charges for sending promotional emails to consumers, according to a study by Jupiter Research.

The web research firm predicts that 268 billion marketing emails will be sent in 2005, a 22-fold jump from the figure for 2000. As promotional emails spiral in number and inboxes become increasingly cluttered, Jupiter forecasts that a tiered delivery system will replace today’s status quo where messages are delivered free of charge.

If Jupiter’s crystal ball is to be believed, email service providers will progressively limit access to subscribers, charging advertisers who want to reach consumers’ primary inboxes.
