Any leads you provide whose websites are blocked from being crawled will not be counted towards your monthly lead count. If we can't process the lead, you won't be charged for it!
You'll be charged once a month- the first time being when you sign up, and then every 30 days after that.
Any number of people at your organization can use your LeadPrimer account, and you can create as many Lead Lists as you like. All that matters for billing is how many total leads your organization has processed each month.
