Here, "evangelize" means to "preach" or "campaign" something. It's often used in the context of religion and telling other people about it so that they might convert. Here it's used in the sense of campaigning or spreading awareness of and promoting a product. Ex: We need to evangelize this product to everyone. Ex: There were a bunch of Christians evangelizing on the street yesterday.
