In search of effective tools to promote vegan diet, 6 years ago we developed a program which we called "Go Veggie for 30 Days". It`s based on daily emails (and recently also on notifications in a smartphone application). Each message contains interesting facts about animals, nutritional information and vegan recipes. The programme turned out to be extremely successful – in terms of the number of participants as well as in the percentage of people who gave up meat. Over 100,000 Poles joined this action and 76% declared they want to stay on a veggie diet.

The construction of the campaign lets us easily measure what people need and what they find most useful. At the end of talk I will offer help to other organisations to set up their own programs and also use our smartphone app.
