  ### Insert or Update List Entries [PUT]
  
  Bulk insert or update entries in the customer-specific exclusion list by providing a JSON object, with a "recipients" key containing an array of recipients to insert or update, as the PUT request body. Maximum size of the JSON object is 50mb. At a minimum, each recipient must have a valid "email" address and at least one of the following keys: "transactional" or "non_transactional". The optional "description" key can be used to include an explanation of what type of message should be suppressed. 
  
  If the recipient entry was added to the list by Compliance, it cannot be updated.
   
  If an email address is duplicated in a single request, only the first instance will be processed.
