Sponsorship will appear on the site, an online members club for opinion formers with membership by application only, and the site has links to entertaining clips and news.
PJ Smoothies will be promoted via a fruit-machine game on the site, and users have the chance to win prizes. The promotion will last for seven months, during which time there will be a weekly prize of 100 bottles of PJ Smoothies, with further prizes to include T-shirts and holidays.
Kathryn McKenzie, spokeswoman for PJ Smoothies, said: "Eatmail.tv allows you to reach the most difficult consumers -- opinion formers who often resist a generic mass advertising tactic.
"It's crucial to reach the small group because they're the ones to spread the word to the rest of the mass consumers."
PJ Smoothies were launched in 1994 by Harry Cragoe, a Californian who noticed a lack of juice in the UK. The range now includes SuperSmoothies and Organic Yoghurt Moothies, launched last year.
Electric Cake is the digital arm of guerrilla marketing and consumer PR agency Cake.
