How can I stop harassing emails?

I am selling a item on craiglist. I received an email requesting information about it. I made the mistake of replaying. Since then, I have been receiving emails about people asking me to meet or call them, but first I need to sign up into a page or something. There are sending pictures with **** women. I just want this to stop. I emailed craiglist, they said to report the email accounts to the sender provider, which I did, and I was sent to this link. I hope you can help. Thank you.
