Email and texting abuse from ex husband continues because of contact required re children. What options do I have?

Divorce is final, but i continue to be harrassed by email and abused emotionally and mentally as ex twists everything I say in regard to my kids which is only reason there is contact. Have a child with special needs and court requires I tell him all things because he has equal custody. He controls me still with manipulation and threats after two years of separation and divorced finalized. I stopped texts long ago and forbid he contact me by text. Have not had one until just today because yesterday I told him he was never to send me an email again. I copied his lawyer and I demanded he was not to ever contact me again. He is emotionally abusive and manipulative and mentally hurtful. Like Gas-lighting and just down right sucks the life out of me by his emails and he is supposed to keep it about kids only. I finally have just refused to read them anymore. I dont care if Iam risking not following the law by notcommunicating to him. He has ruined my sanity and peace for the last time. Help
