Some great advice in this thread. I use a guide from a marketing agency: https://www.dropbox.com/s/l9rhqn1eia...Group.pdf?dl=0

It's as good a breakdown as any I’ve seen on the subject and after reading it I found out that some publishing houses will give this to some of their clients. Basically, it’s a guide to creating your communication and strategy. and working through there.

They sent a couple other emails including how to use social. Can send the signup link if anyone's interested.
