There's one campaign in the very early stages I saw on facebook:

#purpledacaletters

Up to 30 likes and it hasn't even been a day! Here is a quick description of what we are trying to do with this campaign... we will be coming out with more information, videos, flyers, etc. soon!
#purpleDACAletters is a campaign geared towards raising awareness about DACA and all the wonderful contributions DACA students have given to society. DACA students as well as DACA allies will be writing letters that will be sent to state representatives in purple envelopes. More information along with guidelines for people who want to participate will be coming out soon.
