Both of these accounts are free HubSpot Sales & Marketing accounts.
The reason @Phil_Vallender enquired about which version you are using is because the HubSpot Social tools are only available to Marketing Basic, Pro and Enterprise customers. I'll leave it to @Phil_Vallender, one of our Platinum HubSpot partners and top Community contributors, to tell you more about these tools and how these versions of HubSpot marketing accounts differentiate to HubSpot Marketing free.
Okay, so I just found where it says my account is "Free" and not "Basic". I wasn't aware of the difference until now.
Is there a page that explains the difference between the Free, Starter and Basic version in detail? I found the pricing differences, so that's a huge help!
The way I see it, Free and Starter are very different from the Marketing Tool (basic etc).
HubSpot Free and Starter are an evolution of the Leadin product which enabled website owners quickly and easily start to track visitor behaviour and capure their data. This is what Free and Starter enable.
HubSpot Marketing is a full-blown marketing automation tool including content creation, email marketing and social marketing features - these are very valuable and come at a cost.
