The Last Person on Earth, Who doesn’t Use Online Banking Garanti Bank,one of the biggest banks in Turkey, wanted more of its clients to use online banking. Over the years they acquired 1.6 million online users but they were stuck at that number. Despite all the big budget TV campaigns, the number wasn’t increasing. We used Garanti Bank’s database to find out the people who have never used online banking. We knew their names, e-mail addresses and cellphone numbers. We tailored a video for each individual non-user using mobile as the surprise element and created a highly targeted campaign.
