Was it an email that someone sent you through this forum? If so then its probably a scammer, yes - and it should have their member name in the email as well if that is the case.
Generally speaking, sources dont send unsolicited emails. Legit guys usually already have the business, and wouldn't know you from Shinola, ergo they wouldn't know if you were the kind of person they'd even want to do business with and remain safe.
Do people get spammed? All the time.
