Our team at bottlehq.com has compiled a list of more than 500 resources including relevant blogs, communities, tools, and books for marketing professionals and teams.
This 'marketing library' as we call it was originally meant for our internal purposes only, however, we now want to release it to the public.

If you are a marketer or a founder, I'm sure you will find some gold nuggets here!
Best of luck!
