My advice is to always check the full email headers for anything you  
are the least bit suspicious of. Does it appear to come from whom it  
purports to come from ? Is the path likely ?
(Big US companies do not as a general rule forward their
email through small Eastern European ISPs, for example.) If it fails  
this test, treat it as radioactive and don't click, respond, etc.

If it passes, and if the sender is in your field, then use your  
judgement. (I unsubscribe to the "newsletters" that
keep popping up from Chinese ethernet switch makers, for example.)
