我所知道的每个智能手机都可以设置和使用电子邮件帐户.因此，将电子邮件发送到个人帐户，然后让他们取回.

没有用户的同意和交互，没有可用的推送技术将电子邮件发送到电话.

Every smartphone I know of has the ability to setup and use email accounts. So send an email to the persons account and let them retrieve it.

There is no push technology available to send an email to a phone without the users consent and interaction.

创建一个gmail帐户，并使用它来发送邮件...
还是我错过了什么.

Create a gmail account, and use it to send mail...
Or am I missing something.
C# Sendmail gmail
