How to word email cancelling an interview?

[Peakan]

I received an offer for a teaching job today - unexpected as I had been unsuccessful at interview for this school but was called back when another vacancy arose as I had been a close 2nd option. I have happily accepted the offer!

However, I had already confirmed my attendance at 2 further interviews for next week! I need to inform the other schools that I won't be attending but I'm unsure how to word the emails politely.

Does anyone have any advice for wording?

Thanks

I would put something along the lines of

Thank you for considering me for your position. Since accepting the invitation to interview at your school I have been offered a teaching post and have accepted that position. As such I would like to inform you that I will not be attending the interview for x post.

Once again thank you for considering me.

Yours
