50% of campaign success is out of your control

Too much time gets wasted waiting for digital creative, only to find it’s late, lazy or lacklustre. Often it’s poorly-formatted and not to spec, as well as not designed to perform across digital. As your client campaign runs, the digital creative stalls, creative wear sets in and the messy blame game begins.
