Today, I learned about "ringless voicemails." You know exactly what I'm talking about - those AI voicemails that appear in your inbox even though your phone never rang.
There's an entire industry set up to send these out automatically for pretty cheap.
I can not imagine these are in any way an effective form of marketing - especially since my voicemail inbox gets filled with them at least once a week.
No one who can do anything about it gives a shit.
