Unsubscribe link from their emails takes you to this. You then to need to sign in with email and password (I don't know my password) to manage preference. I just want all out!

Oh monster was the worst! I signed up well over 10 years ago and had unsubscribed several times over multiple months once I found a job. They still would send emails 5 days a week. I blocked them and will never ever use them again because of their awful spam. If anyone's curious, I did not find the job through monster.
