We do have the Create or Update Contact integration from Hubspot. What the setup looks like here is: 1. You'll need to have a list in Hubspot that filters those leads when they get created/updated.
2. You could use a custom property field to label them and apply the filter for that in Hubspot so your leads go to that list once they get exported.
3. Depending on how often you check the lead's status in Clay with the Lookup Status from Smartlead integration, you can always re-run the Hubspot column after that and update the label field to something specific about that status.
