Oracle's email marketing uses similar tactics to scammers. Several people at my company got emails that went something like:

"Hi I'm ___ and I'm the new account rep for the services you have with us...."

We don't have any services with them, so this certainly raised an eyebrow. Did someone open an account with them in our name? Did someone at my company subscribe to their services without me knowing?

Discovering this was actually a sales phishing tactic certainly cemented us never wanting to do business with their cloud services.
