Please let me know should you have any inquiries.
which one correct?
"Enquiry" is still the standard British English spelling as far as I know. Though we are getting pretty used to "inquiry".
(I think "questions" or "queries" would be more natural here in British English as well.)
I didn't know that about "enquiries!"
Hahaha! It just looks so silly!
There'll always be an England!
