How to Set Invalid Contacts as Non-Marketing in HubSpot
Use a workflow to automatically mark any contact Koalify flags as invalid as a non-marketing contact, so bad email addresses stop counting towards your Marketing Contacts bill.
These workflows use custom properties that are created automatically by the Koalify – Email Validation app.
1. Create a new workflow
- In HubSpot, go to Automations > Workflows
- Click Create workflow from scratch
2. Set enrollment criteria
- Select Met filter criteria as the enrollment trigger
- Add the filter:
- Contact property → Koalify – Email Validation Status is any of Invalid
- Turn on re-enrolment so contacts are enrolled whenever their status changes to invalid

3. Add the set as non-marketing action
- Click the + to add an action
- Under Marketing, select Set marketing contact status
- Set the status to Non-marketing contact
- Save and turn the workflow on

Any contact Koalify flags as invalid is now set to non-marketing automatically. The change takes effect at the start of your next billing period, so invalid addresses stop inflating your marketing contact count going forward.
