What SendFax.to is
SendFax.to is a cloud fax service for sending and receiving faxes through email and supported fax numbers. Users can email PDF, PNG, IMG, or DOC attachments to a destination address at sendfax.to and receive delivery-status confirmation by email. Inbound faxes can go to up to two email addresses, and each fax-capable DID can be associated with up to 100 authorized email addresses or domains. Users can scan multiple pages with a mobile device and send from a computer, tablet, or smartphone. Multifunction printers can send by scan-to-email and print inbound faxes through email-to-print. Inbound routing to T.38-compatible PBXs, ATAs, and gateways is also supported. Its API can send faxes and provide fax information or inbound and outbound callbacks; callback URLs must use HTTPS. An optional device connects up to two physical fax machines. The service is paid, with pricing from $17.99/mo, and has no free plan. The maker describes it for businesses that want to fax without relying on a traditional landline fax machine.
