我的尝试：

如果有4个客户那么....
第一位客户获得4条相同的消息，
第二位客户获得3条相同的消息，
第三位收到300万条消息，最后一位收到1条消息br />

推荐答案
此行正在为您的邮件添加新收件人
This line is adding a new recipient to your mail
mailMessage.To.Add(new MailAddress(CustNameArray[i]));
您需要在发送前清除收件人列表下一条消息。
否则
消息1发送给收件人1
消息2发送给收件人1和2
消息3发送给收件人1,2和3
消息4发送给收件人1,2,3和4
You need to clear the list of recipients before sending the next message.
otherwise
Message 1 is sent to recipient 1
Message 2 is sent to recipient 1 and 2
Message 3 is sent to recipient 1, 2 and 3
Message 4 is sent to recipient 1, 2, 3 and 4
