Activities
Activities are the different engagements that your team in HubSpot has with the records in the CRM. They could be leaving notes on an open deal, meeting with a company, or calling a prospective customer. Just like you can create and associate records via import, you can create and associate activities using the import tool.
Once imported into the CRM, you can use these activities to report out on the productivity of your team, and see who your top performers are.
