We are seeking to fax a single flyer to thousands of fax recipients whose fax numbers we store in an Excel worksheet. We intend to fax to this list once; or possibly twice at the most. We want to avoid having to make a equipment purchase to accomplish this. We've done some self-educating on the web yet lack actual experience doing something like this. Does someone have experience with, or first-hand knowledge of a reputable online service or PC-based application that can handle mass faxing to thousands?
