Steak has been briefed with overseeing the brand’s digital marketing on a number of fronts, including paid search and digital display, as well as helping drive overall sales and picking up new customers.
It is not known who Steak pitched against for the brief.
Moo.com’s core business is printing business and greeting cards and it now has customers across 180 countries.
Phil Burgess, client service director at Steak, said: "Moo is one of those brands that you can’t help falling in love with a little bit, because it mixes traditional skills such as print and makes it accessible to everyone via the web."
Steak’s clients include Virgin Holidays, Debenhams and PC World. Globally, the company employs 85 full-time staff with its main strength lying in English speaking markets: the UK, US and Australia.
