我用了一位网友的code省了10元，我也把我的code 007731写出来 (有效期至9月6号），双方都受益。具体手机发email方法如下：
send the message to this number: 0000000000 (that is 10 0's)
Write the text message in the following format:
address@domain.com Here is the message
(in other words, first the email address, and then a space, and then the message)
我已经测试过，非常简单快捷。
