I receive an email like this every month or so:
“Hi I have a business law matter for which I need assistance. Kindly confirm if you are available to handle such matters. Thank you for your time and consideration. Please contact me via my personal email for more details”
You can tell it is a scam because there are no details furnished in the email. I never respond. Be wary of any such communication. I am not sure how the scam works, but this cannot be a real matter from a real client.
Another variation is the email that states that the purported client has a “business sale” matter. Again, without details you know that responding is a waste of time or worse.
