We are glad if you do not use qq.com e-mail address.
We are glad to have order from you, and always doing our best. But it is super sad to have return of our e-mail as delivery failed. Seems qq.com server is often shut down or often have permanent error. Everyday, we have to spend our time to send mails again. Yet is is ok as long as failed mails are sent by us manually, but when they are automatic mails? There are no reports.
We are so happy when you do not use qq.com e-mail address on the view point of safety shipping.
Thank you for your understanding in advance!
