Quick help - contacted the wrong external examiner

[DirtyDennis]

I've got a PhD student submitting soon so I'm contacting examiners.

I contacted someone this morning (hasn't replied yet) but then realised that she's totally and completely inappropriate for reasons I wasn't aware of before I contacted her.

Should I wait until she gets back to me before kindly telling her she's not needed. And when I do tell her she's not needed, how do I tell her this?
Shall I spin her some bullshit about there being a delay to the thesis and then just never contacting her again, which is bad form and makes me look a twat? Or shall I be honest about her being inappropriate, in which case she'd surely wonder why the holy fuck I contacted her in the first place, which also makes me look a twat?

Fortunately it's not hugely my area/discipline so it's not a huge issue if I do make a bit of a twat of myself but I don't want the awkwardness.

Please help!

Just email her again now before she replies and say you contacted her in error. Apologise but dont give some big explanation. Not a big deal.

Don't make yourself look silly for no reason.

Either say you contacted in error or that a change in the situation means she is no longer needed, sorry for the bother.

How does this sound (really wanky?) :

Dear Prof X.

Please accept my apologies, I sent this email in error.

Dear Prof X

Please accept my apologies, since I emailed you this morning, there's been a change in the student's situation so please ignore my last email.

Apologies for any confusion or inconvenience

Does that bottom one sound ok?

God I'm such a fucking knob

They're both / all fine. Don't lie though- change in student's situation- no need!

The bottom one sounds fine, although I'd say disregard rather than ignore.

THe bottom one is fine. I wouldn’t give it a second thought if i were her and received this.

Okay, I sent it

Thanks for your help - sorry for my panic!
