GMail alerts on senders which might be phishing

I noticed a great new alert today on my GMail account. Previously I’ve received emails from David Cohen on his business email, however he suddenly sent me an email from his private email address. This sparked Gmail to give me an alert, saying that this individual might be pretending to be someone they’re not. Pretty great. An alert like this might cause the recipient to think twice.

The idea is to store firstname and lastname metadata a long side with a senders email address. If all of a sudden the firstname, lastname combination is detected from a different sending email address, the alert can be produced.
