The mailing was sent to 25,404 Dental Professionals, with a target of 2,032 responses (8%). We actually received 3,487 responses (172% over the target). This led to an additional 34,920 opportunities for Dentists to recommend Listerine Advanced Tartar Control and to supply samples to their patients. With 83,688 recommendations overall, this level of recommendation will translate into £67,260.05 in patient sales of Listerine (in our first year), giving us a positive ROI of £2.99 per £1 of budget spent, for the campaign.
