You can import contacts that already exist in your Gmail account into HubSpot. You'll first export your contacts from Gmail as a CSV file and then import that CSV file into your HubSpot contacts database.
- In your Gmail account, click the Mail dropdown menu in the upper left-hand corner, and then select Contacts.
- Towards the top of your screen, select More > Export.
- In the dialog box, select the group of contacts you’d like to export, and choose Outlook CSV format as the export format. Then click Export.
