Hi folks we have added per email contact properties that can be used in lists, & workflows.
We are adding the following global reply properties now as well:
first_reply_timestamp, last_reply_timestamp, marketing_email_replies (count of mkt email replies)
You may already see these in your HubSpot account as contact properties. But they are not yet being updated. We should have something out by the end of the week to start actually populating these properties
