I'd say it depends on how much homework was done by an attacker. The company I work for was adding some new services. One of the service setup emails came in and was off just enough that I reported it rather than following it, and yes, it was an internal phishing test, but one I found very valuable because the service providers could be hacked, and the URLs that are used are generally terrible if you're trying to figure out where you're going.
