What e-mail address should I use to send e-mails to British universities? If I want to contact the school and ask some interdisciplinary questions, can I use QQ email or 126 email?

Don't use QQ e-mail, ................ Using QQ e-mail will create a history of blood and tears! Hotmail or 163 can be used ... don't use QQ! The email I sent to the school with QQ mailbox has never been ignored by me! Hotmail can reply on the same day.
