Being on a list is a symptom. Delisting without fixing the cause gets you relisted within days, so the order of work is: find what sent the mail, stop it, then request removal. Common causes are a compromised mailbox, a web form with no rate limit, a misconfigured relay, or a shared IP where somebody else on the same host is the problem.
