What’s the worst cold email you’ve ever sent?

I was testing the Gmail API a year ago and was sending dumb emails like "send me book" to me.

While coding, I've noticed the latest email didn't arrive to my inbox. I checked...and it turned out (by mistake) I've entered a famous author's email :O

Funnily, he replied with "Ok I will". Lol...

I sent a reply, apologizing and explaining the situation. He said: Np man, that email made my day :)

Somehow the worst email I've sent turned out to be also the best...
