- Go to the Contacts tab from the main navigation
- Select the Filter button in the top right corner and then select Email Deliverability
- Select the necessary filter and then click "add"
- Click Close and Apply to view your filtered list
If you'd like to remove these contacts from your database click the orange Actions button and then select "Delete Contacts"
