Rowdrop does not connect to HubSpot yet. The live, read-only connection to your lists, reports and objects is coming soon. For now, import the CSV you already export from HubSpot. It stays in this browser.
The first row must be the column names, as HubSpot exports it.
Optional. Importing the same name again updates it.
Rowdrop will not send email yet either. It builds the file for you to download.
