EmailInsider: The Last 30 Days of Email
Bill McCloskey's Emerging Interest released a month's worth of email tracking data to draw a picture detailing which companies are using email to sell product.
The top market sectors using email marketing proved to be coupons and promotion, home-based businesses, credit card companies, business services, home study, online universities and computer products.
The coupons and promotions category is made up of companies that use opt-in email addresses to send third party offers, including companies such as Remodel 4 Free, owned by 123 Click; SubscriberBase, owned by FreeSlide; Franklin Surveys, owned by SilverCarrot; GroupLotto and Winhundred.com, both owned by Traffix; Enjoy Savings, owned by Advertising.com; Quality Health, owned by Marketing Technology Solutions; WinSweepstakes.net and Jackpot.com, owned by The Vendare Group; and It's Your Opinion, owned by Permission Data LLC. The rest of the study details the other categories and reveals that most big brands are still not using email in their marketing programs.
