Where this gets interesting is that very often you can see through the envelope slightly.
It's similar to if you hold a flashlight to the back of an envelope and can then see 'through' it to read the paper inside.
- nemomarx 1y agoThis is why some envelopes have a pattern on the inside for privacy, right? I thought that was standardized a while ago for anything official and important. Smaller card sized envelopes maybe not though
- somehnguy 1y agoYeah I believe so. Going through some of my old informed delivery emails I see a few with the crosshatch privacy pattern which seems to work reasonably well. I wonder if manipulating the image in some way (brightness, etc) may reduce that effect. I also have a number of mailings from my bank that include things like account balances & numbers, with no privacy pattern. So it seems hit or miss.

- somehnguy 1y agoJust like USPS should not send you images of other peoples mail, a lot of mail isn't in the type of envelope they should be. I'm looking at multiple bank statements where I can read balances. Another vector is the plastic window many envelopes have to show the addressee printed on the paper inside. I have another healthcare related letter I can read through that.
