Simplefax is designed for low-volume users who occasionally need to send a fax. It follows a 20/20 rule: you can send up to 20 faxes each month of up to 20 pages each. There are no additional costs, subscriptions, or recurring fees.
To get started, simply drag in a PDF of the document you wish to send. Then type in your email and the recipient's fax number, and you're good to go! You will receive an email once the fax is delivered. Each month, the limit of 20 faxes will be reset.
This is only good to use on MacOS
