Everyday, I received junk mail from udemy. I have been doing the unsubscribe with no luck. Does anyone have a similar experience?
I've never heard of them, so I have no info about getting them to stop other than calling them up and yelling at somebody If you haven't tried it already, you can mark the emails as spam and, maybe, your email server will from then on recognize further messages as spam and handle them accordingly. Or, you can just block the email address from sending anything to you.
Udemy sort of offers MOOCs. People can design and offer their own courses. Most of them cost money. If they don't stop, you can file a complaint with the FTC under the CAN-SPAM Act. I would first try contacting Udemy to inform them about the problem.
