How do you know they were from FitBit, rather than from a spammer with their From address set to FitBit?

- michaelrhansen 10y agogood question - i believe the email address was Fitbit but will confirm
- cjbprime 10y agoAh, sounds like you don't know about from addresses: they are specified by the sender, and not authenticated. A spammer can send email that appears to be from anyone else, until you look at the validated headers (like "Return-path:").
