According to a survey of over 2,000 adults, 96% of Web users who have provided any information online in the past year have provided their email addresses.
Overall, 85% of adults said they would be willing to provide their email address to brands they trust to receive special offers or more information.
"Consumers are willing to opt-in to the right kinds of advertising if they're provided with relevant, actionable creative," said Zephrin Lasker, CEO and co-founder of Pontiflex.
Meanwhile, 73% of online adults said they would be more willing to make a purchase from a brand they have signed up with, and 68% are more likely to trust a brand they hear from often.
Separately, the September survey found that less than half -- 47% -- of online adults have ever intentionally clicked on an online ad. Whether they have ever experienced the inconvenience of being redirected by ads or not, 78% said they disliked the idea of leaving their destination when they click on banner ads.
If clicking on online ads was ever popular among consumers, there's plenty of data to indicate that it isn't anymore.
Indeed, the number of people who click on display ads in a month has fallen from 32% of Web users in July 2007 to only 16% in March 2009, according to recent data from comScore in conjunction with media agency Starcom USA and behavioral targeting firm Tacoda.
Worse still, an even smaller core of consumers -- representing just 8% of the Internet user base -- accounts for the vast majority, or 85%, of all clicks.
