MX Guarddog was started in July 2006, with the concept of offering spam & virus protection in exchange for a text link back to a website operated by IK2 Limited (the parent company of MX Guarddog). No cash payment for service need ever occur - essentially making the service free. Over the years we have received many inquiries about a paid service.
Due to the number of requests we have received for a paid service we started selling tokens for a cost of $0.25. This makes the cost of purchasing the service $0.25 per email address per month.
No user is required to purchase tokens but the option is there for anyone to cover their monthly cost in part or in full by purchasing service tokens.
