#CadburySnowball Fight

Case Study



To deliver irrepressible joy throughout the Christmas season, SoPost worked with Elvis Communications, in order to create a Cadbury ‘Joy Spike' by bringing the joy of a snowball fight to Twitter. In doing so, we gave away some of Cadbury's most well-loved Christmas products: Snow Bites.

A promoted tweet was launched at 1pm on 11th December 2014. Anyone who saw the tweet could click on the link to “Hit a friend with a #CadburySnowball!”

By doing so, consumers were directed to SoPost where the snowball thrower could connect with Twitter, and select a friend to ‘hit' with a #CadburySnowball. When their friend was hit, the recipient could input their postage details to receive the free bag of Snow Bites.
