The campaign, which launches this week, was created by Proximity London working with Hive Associates, which provided the interactive postcard or dynamic image component of the campaign.
The use of the Dynamic Images lenticular format, better known for use in the six- and 48-sheet outdoor market, is a break from the more typical multi-page format DM mailer.
Marc Edmunds, managing director at Hive Associates, said: "Dynamic Images is probably better known for use in outdoor market. But its value proposition as a DM piece is just the same. Its interactivity gives brands the chance to make an immediate impact, significantly increasing consumer response and recall."
The postcards back the launch of Persil's new Liquid bottles, just days before they hit supermarket shelves. The front of the postcard features 24-frame dynamic image animation showing a pouring bottle, with the strapline "A big improvement from every angle".
On the reverse side, the strapline "The liquid you love is now even better" heads an invitation to consumers to comment on the new bottle design on Persil's website in return for a £1 off voucher and the chance to enter a prize draw.
Graham James, production manager at Proximity, said: "Dynamic Images gives direct mail specialists the opportunity for innovation. Not just through its immediate curiosity value but through its ability to visually communicate a products value proposition. DI was especially fitting for a mailing that invites consumers to interact."
Dynamic Images are capable of encapsulating up to 24 frames of any film sequence, or 3D rendering, and represents the cutting edge of imaging technologies available for use in the out-of-home media market.
