My fingers seem to be used to the delete button these days with the rise of scam e-mails aka spam. There was no exception though when I received this e-mail. I know it looks so official and you would panic if you thought someone was trying to register a similar name to your business. I would advise that you "Google" the e-mail address before responding to any such e-mails.
I know we all want to sell but if you have managed to get my details, why don't you bother check the website. The funny thing about the above e-mail is that the whoever is sending it is in India and not Australia - ehm!
