The activity, through Red Cell Response, is aimed at generating awareness of the product. Winner features on in-branch POP and dump bins from which consumers can pick up free car-related giveaways.
"We wanted to add value for consumers by giving them something useful, as well having an in-home reminder of Esure's offer," said Nigel Owens, director at Red Cell Response.
The push also gives branch staff the opportunity to win a spa day.
Mary Davidson, head of partnership at Esure, said the execution was "a witty and relevant campaign image that maximised the strength of the 'Calm Down' property".
