I wanted to respond to this question on this site: http://www.fluther.com/disc/40...ealed-envelope-tricks/ but didn't want to register so I'm just going to post the answer to that question here.
It's really simple, just get a powerful flash light (I prefer LED ones that have like 5 LEDs), put it under the letter you're trying to read and presto. Using natural light or indoor lighting is generally not enough, you actually have to press the mail against the flash light so the focused beam is pushing through, revealing the text.
