Unless you're a bank or a government or an hospital or idk
Seriously I had to submit a document by fax like last year to my bank. Ive now switched but still. I had to pay some weird online fax service just to send it because I didnt want to print out and post my documents....
that looks like it came from a sms-to-fax service or something. a fax machine is usually just a remote photocopier but this one has like a specific header and looks like it was generated digitally rather than scanned.
