Block Recipient

• 1). Block people from receiving your messages in the most obvious way--eliminate them from your address book and do not send messages to them.
  
  
• 2). Open your email options and see whether there is an option for blocking a recipient. Most programs have this option, which keeps you from accidentally using a function like "Reply All" to send a message to someone with whom you do not want to have communication.
  
  
• 3). Input the email address into the email blocker and click "Block."
