Know or assume what? That the email was automated? Yeah, I mean I don’t know 100% but I highly doubt a human analysed the situation and typed an email.

What seems more likely to me is, a request came from my app to some bank server. The server detected the request coming from Cuba and flagged the account as having suspicious activity, that in turn triggering an automated message.

Maybe there was indeed a guy somewhere in an office who saw one request to my account coming from Cuba and decided to have some fun and said he’ll turn my account off. I don’t know. Whatever it is, it’s creepy it happened.
