Thanks for the reply Tom,

Are you talking about one thread for all the cfmails (outside the loop), or
one for each mail? I'm assuming the latter wouldn't be a good plan where
there might be thousands of emails, particularly on CF8 Standard.

Also, with the former option, if the thread was named then I could
presumably check that a thread of that name wasn't already running and not
run the code if it was - my thinking was this could help deal with double
clicks on the submit button. I'm looking at this at the moment.

I'm still not convinced that the duplicated emails were caused by the user
double clicking though.

Cheers

Will

Yes, CFTHREAD the sending assuming the mail server can handle it.
A simple thing to do for the button is use javascript to disable it onClick.
'course, if javascript is disabled there isn't much you can do except embed
a one-time token in the form, and invalidate the token the first time it is
used.
