Great question, @Anonymous. At INBOUND 2016 we introduced the Growth Stack, which is one holistic set of tools that you need to grow sales and marketing. As a result we definitely want sales and marketing to use, and collaborate, using tools within HubSpot.
For example, within the HubSpot CRM you can “@ mention” any team members that are a part of your HubSpot account and pull them in to the conversation. On the marketing side, as your writing content using Composer, you can also collaborate and review content using the same mention functionality.
As marketers generate new contacts in the database, that information can be used to score leads and then pass the most relevant ones to sales. All of the HubSpot Sales tools utilize the same database and the same information can be used in emails from reps. A great example of marketing and sales using HubSpot’s tools is eZcater. Check out their video below for how they use the tools for sales and marketing alignment.
