It's actually much worse than sending incriminating documents through the mail, even printed brazenly on a postcard.
To capture incriminating physical mail, the authorities have to already be monitoring you at the time you send the documents. With email they are typically able to go back and capture emails from days, weeks, and years prior.

I know I'm nitpickig, but the USPS photographs of all pieces of mail and digitizes it. This information is considered metadata and is not protected against unwarranted searches, so postcards are much worse (for privacy), because even the small-town PD can get access to them without having to look for an "IT guy" to help. Email requires assistance from a TLA agency (or a search warrant served to the mail provider).

Thanks, I had no idea.
While doing some genealogy recently I found that a distant ancestor had unclaimed mail in the post office shortly before he died.
I found it vaguely amusing to envision walking in and asking for it now, 125 years later; I guess some distant descendant of mine might be able to ask for a photo of mail I'd sent or received.
