Carat Interactive, one of the world's largest interactive agencies, has been selected by Vonage for digital marketing services. Based in Edison, New Jersey, Vonage is redefining communications by offering phone services directly to cable and DSL high-speed modem subscribers. The broadband phone service provider has lured 20,000 customers since launching Vonage Digital Voice one year ago. Carat Interactive created and launched an advertising campaign designed to motivate potential customers by informing them that there is a viable alternative to their costly and complicated home phone service. The campaign uses larger rich media ad units including leaderboards, targeted messaging units, and skyscraper ad executions to emphasize the unlimited national and local packages offered by Vonage.
