Fax to email keeps a business’s existing fax number working for the suppliers, government departments, and older systems that still rely on it, without needing an actual fax machine or a dedicated analogue line sitting behind it. Incoming faxes arrive as PDF attachments in a regular inbox, and outgoing faxes can be sent the same way.
This is typically set up as a straightforward add-on alongside a hosted phone system, using either an existing fax number or a new one.
