###Workaround for welcome latter

1. Subscribe the user to List

    ListSubscribeMethod req1 = new ListSubscribeMethod();
    req1.apikey = API_KEY;
    req1.id = LIST_ID;
    req1.email_address = "xxxx@gmail.com";
    // There is no need to send confirm letter
    req1.double_optin = false;
   
    Boolean res1 = client.execute(req1);
    log.info("Result: " + res1);
   

2. Create campaign for specific user in the List

    CampaignCreateMethod req6 = new CampaignCreateMethod();
    req6.apikey = API_KEY;        
    req6.type = CampaignType.regular;
   
    // fill the email content
    TestOptions options = new TestOptions();
    options.list_id = "00d7e7e094";
    options.subject = "ByeBye";
    options.from_email = "byebye@gmail.com";
    options.from_name = "Girl";
    options.to_name = "Fan";
    req6.options = options;
   
    TestContent content = new TestContent();
    content.text = "Hello World";
    req6.content = content;
   
    // Filter the specific segment of the List
    Options op = new Options();
    op.match = "any";
   
    Conditions cond = new Conditions();
    cond.field = "email";
    cond.op = "eq";
    cond.value = "xxxx@gmail.com"; // yes, it is the mail registered before
   
    op.conditions = new ArrayList<Conditions>();
    op.conditions.add(cond);
    req6.segment_opts = op;
   
    String res6 = client.execute(req6);
    log.info("Result: " + res6);
   

3. Send the campaign

    CampaignSendNowMethod req3 = new CampaignSendNowMethod();
    req3.apikey = API_KEY;
    req3.cid = res6; // The campaign created before
   
    Boolean res3 = client.execute(req3);
    log.info("Result: " + res3);
