Dunkin' Donuts ran a campaign on Facebook and Twitter to promote their Coolatta drink in June 2009. The campaign goals were to attract customers to Dunkin' Donuts and their social media pages, and keep customers engaged without overwhelming them. Dunkin' Donuts used Facebook to launch the Coolatta and had customers post pictures with the drink on Twitter to enter daily and grand prize giveaways, including air conditioners, gift cards, and electronics. The evaluation found that using limited social media and unique contests was an effective way to drive traffic and create loyal customers.
