Does anyone have any thoughts on choosing which email lists to stay on and which to unsubscribe to?

I've been spamming my senators and rep with emails--basically every time I get an email asking me to send an email to them, I've been doing so. I get great joy out of flooding their inboxes!

The downside of this frequent activity is that I've been added to more and more email lists to the point where I'm now getting at least 20 emails a day asking me to sign a petition, send an email, donate money, or just be informed. It's definitely too much, but I'm not feeling like I have a good idea of how to decide which ones are worth staying on and which I should unsubscribe to.

I also feel that this habit of sharing mailing lists between all these progressive organization is not a great strategy--my fear is that people will become so overwhelmed by the deluge of emails that they'll just start unsubscribing to all of them or deleting them immediately.

Does anyone have any thoughts on this topic? Commiseration would also be acceptable!
