** Money Back Guarantee & How It Works: If after 90 days you’re unsatisfied for any reason, we will refund the monthly minimum of $500 for a maximum potential total of $1,500.00. If you were to exceed $500/month from imported leads (up to 500,000), or choose to use optional paid 3rd party services like data appending, phone validation or email validation, those fees (additional leads or add-ons) are separate and non-refundable.
