I am running a simple CL campaign in which the response email has my affiliated link(my domain name with a double meta refresh.). It looks like some of the CL responders are having a hard time getting the link to work since they write me back saying the link is not working. For others however it works just fine as I am seeing the commissions roll in. Anyone have an idea of what could be causing this? Is maybe their IP address being blocked by the landing page?
