Emails better though because with a fax machine you can only address it to the phone number, which is usually one number for the entire organization or for the entire department if it was a big company.
With email you can individually address it to the actual intended recipient.
I think you can send faxes to computers and they just get received as emails with attached PDFs. It’s not great because of course it’s just a picture of a document, so it’s not searchable or editable unless you run it through an OCR program.
