Hey @hs-user,
Matthew’s active list suggestion is how I would recommend that most people do it. I see that you are still looking for a way to purge low quality contacts and cut down on your total.
Full disclosure here — I work for them, but I think Insycle could be potentially what you need. First, Insycle’s health assessment is great for identifying records to delete. It automatically audits your contacts and flags records that are missing data, contain invalid data, have common data errors, or are duplicates.
You can combine several variables for advanced filtering and identification, using any field in your HubSpot database, and preview them before the purge is pushed to your live data. Then, you can schedule regular automatic data purges on a set schedule, using the templates that you build. Each time an automatic purge runs, a .CSV of the removed files will be emailed to your chosen email so that you can anaylyze and keep an audit trail in place.
We actually recently published a guide to this feature, if you’d like to check it out: Declutter Your CRM By Purging Low-Quality Data Automatically
