Hi there,
We’ve noticed that you haven’t used your Gmail account,wanghaiyan@ gmail.com,for quite some time.In order to make Gmail better for our users,we’ve added a lot of things in the last few months and we hope you’ll want to start using your account again.
Stop worrying about storage(存储量).Your account now has 5000 megabytes(兆字节)of free storage and our plan is to continue growing your storage by giving you more space as we are able.
The Gmail interface(界面)is now available in 12 languages.If you don’t see the language you want on this list.Look for it in the future because we’re going to keep adding more.
We’re still working hard every day to build for you the best email service around.But to keep Gmail great for our users.we may have to close inactive accounts after 9 months.So,we hope you’11 give us another chance.To log in(登录)to your Gmail account,just visit:http://gmail,google,com.
Thanks.
