Hiver uses the sender's email address to find matching contacts, companies, and deals in HubSpot and displays their details, including the record owner, alongside your conversations. Contact and company details are also synced into Hiver to keep this information up to date, and record owners can be used in Hiver automations to route conversations.

When you choose to log an email, Hiver adds it as an email activity to the existing HubSpot record you select. Any attachments on that email are uploaded to HubSpot Files and attached to the logged email. Viewing details and logging emails do not create or change contacts, companies, or deals.
