Postalytics requires a credit card on file in the account for subscription billing and Campaign purchases. When paying for a Campaign, you can either use the credit card on file or enter a new credit card in the Campaign Wizard. Or, if you’ve previously purchased Direct Mail Credits, you can choose to use those.
Postalytics can manually create and send out an invoice for the advance purchase of Direct Mail Credits. This must be done with enough time for the invoice to be paid in full so that the Direct Mail Credits can be deposited into your account prior to the Campaign send. Let us know if you’d like to pay via invoice so that we can assist.
