emailing teachers

Today I was told by one of my teachers (who is also assistant principal) that I am no longer allowed to email her as they are apparently getting too informal,even though they are actually more formal.

ok, so I started emailing her roughly 6 months ago,they used to be asking to talk or going over personal problems, She said I wasn't allowed to email her about things like that, which I can understand, so I stopped.

revision was arranged for today but no one knew the exact time so I emailed her asking where it was, When it was and what we need to bring.

Today I was told that I wasn't allowed to email her at all anymore, even about academic stuff, which I found frustrating, as if i do email her she will have to report it.

So I just wanted your opinions on what I should do and if you feel it's right for her to stop me?

It's not personal, she's covering her back for child protection/safeguarding reasons.

I don't blame them, especially when you see all these abuse cases etc on the news. A very litigious world we live in.

Curious as to whether or not you were e-mailing from your personal address or school e-mail? Some teachers are happy to receive e-mails from your .sch.uk address but not a personal one.
