Never saw any activists around our way - although I delivered 3 different sets of leaflets to a number of "local" routes.
Lots of stuff through the mail from Labour (think about 4 different items). Dh got one piece of literature personally addressed from Tom Harris (our now former Labour MP) but I obviously wasn't worthy of an appeal to vote for him. 
Both of us got a letter from the SNP - but then, they knew we were "Yes" voters.
Got lots of literature hand-delivered by the SNP only one of which was "delivered" by me 
Despite living in a Tory ward when we had smaller wards and being on our Tory councillor's list, we only got one communication from the Tories.
As a former Labour voter (pre 1997), I think Labour is too far gone to recover in Scotland. I think it will totally have to re-create itself - probably from elements of the SNP after it begins to splinter after if we achieve independence.
Before that happens, I think Labour has made a BIG mistake trying to fight the Tories on their own grounds of a neoliberal economic orthodoxy (what is f@king "liberal" about "austerity" economics 
) , as they were never going to win that battle. They should have changed it to a war on competing economic principles: there are* other economic models which deliver growth, not at the cost of the poor and vulnerable and which don't assume the fallacy of "trickle-down" economics
