I almost sent out over 1500 letters from the National Sales Manger once.
Not a spellcheck thing, but a typo thing AND it had been checked by 3 other people before I went to print.
Most of the letters had been put into their envelopes (most done by me) before I saw the error. I then had to redo them all.
I was *not* happy. It was my fault but I do blame the 3 other people (one who just so happened to be our
PR Manager) as well.
