Send a paper check via physical mail couriers. Paper checks aren't the newest or the fastest way to send money to someone, but when all else fails they present a time-honored method of sending a payment.
Multiple mail speeds are supported and every option except standard mail (the "Mail" enum value) supports tracking info once the check is printed and shipped.
Note; a phone number for the recipient must be provided if the chosen mailType is FedEx. This is used in case FedEx couriers need to contact the recipient to coordinate delivery.
