There are many websites that enable visitors to send and receive free faxes online. These free services have a limit to the number of faxes that can be sent per month, and a monthly fee is required for heavy users.
For those who only need to send the occasional fax, free services provided by online faxing companies are generally sufficient. For those who need to send numerous faxes each month, the purchase of a monthly plan may be required. Monthly plans typically range from about $10 to $40 per month, as of 2015, and are priced in accordance with the volume of faxes sent and received.
