To gather interest for our heavy truck and event, we send out the heaviest invitation ever: a heavy stone slab. With the information imprinted.

Instead of printing on paper we printed the information regarding the Actros SLT and our event on a heavy stone slab and sent it to our target audience. The mailing was a one-off physical mailing without other supportive advertising efforts.

Our event had a huge attendance. Also, in the first eight weeks following the event the number of appointments in our client service centers increased up to an astonishing 4 percent.
