NatWest has unveiled a campaign with M&C Saatchi, which includes a YouTube homepage takeover and a special microsite to promote the Pay Your Contacts functionality of the NatWest mobile banking app.
The microsite, which is set to be live for at least the next three months, allows users to create a personalised video to remind mates about an IOU.
SapientNitro was the digital production agency involved and Zenith Optimedia handled media planning and buying.
