eFax allows free receipt of faxes.

Many blue moons ago I used to have a free eFax account to receive occasional faxes. Then eFax went rouge on its freebie crowd, yanked all free accounts, and now only has two options, Plus and Pro. Either of these options cost more than a fax machine. Turns out at this day and age I still need to receive very occasional fax from someone who is not fully living in clouds. All free fax-in options I've checked are setup in some way that essentially makes the whole service moot. For example, faxdesk offers a free fax-in service but the phone number lasts only 4 hours, and you cannot order more than one number every 48 hours. Technically can work, practically, not very much.

Turns out that eFax still has this free fax-in option. It is located here. Go and get, and have your faxes sent to your mailbox free. The number is going to be chosen randomly for you, but who really cares.
