The HubSpot–lemlist integration can sync contacts, companies, mapped properties, and campaign activities between the two platforms. In lemlist, please check:
- Go to Settings → Integrations → HubSpot and confirm the connection shows Connected.
- Under General settings, ensure contact creation/synchronization is enabled.
- Under Activities, verify that email activity synchronization is enabled.
- Check User Mapping so the lemlist sender is mapped to the correct HubSpot user.
- Open the Logs tab and look for failed or aborted sync events.
Sent emails and replies should generally appear on the matching HubSpot contact record under Activity → Emails. Opens and clicks may appear as notes instead, because HubSpot restricts third-party applications from writing those events to dedicated email objects. The contact must also already exist in HubSpot, or contact creation must be enabled, and the email address must match exactly.
The free HubSpot seat may affect the user’s permissions or ownership mapping, but it is not necessarily the reason that activities are missing.
Also, please note that field mappings are not retroactive, so mappings or activity settings enabled after a campaign was launched may not backfill historical data.
