Hey @robert l12​ 👋🏼

The filter combination 'Leads' and 'Email is Unknown' should show these leads 👇🏼

I tested this to double-check for you! If you aren't getting results, I would suggest checking that those leads you have in Contacts actually don't have emails attached to them. You can check this by adding 'Emails' into the columns in Contacts here 👇🏼

If there are leads with no emails showing there - I would suggest reaching out to one of our support agents via the Messenger with a few of these examples so they can investigate this for you 👀
