Having conversations documented in emails really saved my keister on multiple occasions. Admittedly on one of those occasions, the effect wasn't immediate -- the manager in question basically rage-quit the conversation. But she put a lot more thought into getting confrontational in future disputes. (Although I have to clarify that this was a fairly dysfunctional environment (and had been for a while), due to which I figured getting things in writing was the safest choice. In future more cohesive settings, I didn't bother with this as much, as the teams tended to have more integrity.)
