Interestingly enough, the Brits ran their own propaganda campaigns against the Germans at the time though they were a heck of a lot more effective. One particular radio station went something along the lines of:
"Hello fellow U-boaters, this is German Atlantic radio. We've got some great songs for you, including some of the greatest from the Fatherland and some special requests from you, the listeners. We'd also like to extend a happy birthday to our friend Dietrich in U-569. Coming up, the football scores between the crew of U-421 and U-94 during their shore leave in France. But first, breaking news, this just in, your home has been bombed by the Americans. Hey look, if you want to leave the Kriegsmarine to see if your family's alright, I'm not blaming you. I'm sure everyone of us would do the same thing. If you want, you can talk with command after you get back shore, they'll be quite understanding. But now, on to the match scores."
This program caused a very serious danger of German naval bases being undermanned.

That must have unnerved everyone in the u-boats if their personal info were known
The Brits were VERY good at gathering intelligence.
Having cracked German encryption was a big part of that, IIRC. (After doing a bit of searching, it seems that, for example, decoded Enigma transmissions enabled an airstrike that crippled the Bismarck's steering and left her vulnerable to the attack that ultimately sunk her.)
