Arc joins Joshua, Billington Cartmell, Logistics and Chemistry on the FMCG giant's confectionery promotions and customer relationship marketing roster.
The agency was appointed on the strength of a one-off project aimed at driving sales of Nestle's children's range.
Nestle is focusing on CRM and below-the-line activity to promote its products. Its £2m online KitKash promotion, through RMG:Connect and MindShare, entered its second phase last year.
At the end of last year, Nestle appointed Joshua to handle its £15m CRM activity across its beverage brands over three years.
In 2003, Arc developed Masterfoods' £10m Chocollect CRM drive for brands including Mars, Twix, Snickers and Bounty.
