FaxReceipt sends a fax online to any number in the US or Canada, from any country. Upload a PDF or a photo (up to 25 pages), enter the fax number and pay once for that fax, with no account and no subscription. The service is priced at $2.99 per fax, and the cover page is free.
FaxReceipt dials the number, retries if the line is busy, and emails you a transmission report showing that the recipient's machine accepted the pages. It is made for the one-off fax that a US agency, a doctor's office, a bank or a court still asks for.
Most online fax services want a monthly plan and an account, even when you need to send one fax a year. People abroad dealing with a US agency or a bank had no simple way to send one page and know it arrived. We wanted to pay for the one fax and get proof of delivery by email.
