I have used something similar but for a slightly different problem. A long time ago (at the start of my career) I started using a folder called “Curious George” where I put all those really interesting emails with new ideas, trends, etc. The problem is not so much death by a thousand cuts but falling down a rabbit hole of some cool idea and losing an hour of focus. I collect all those dangerous emails and then go through them periodically. The difference is that none of these really require a direct response but some of them will result in me starting one of those annoying email chains that will steal others time - so it is much better to allocate time to read thoughtfully so I am only sending along the useful bits.

For those daily thieves of attention (described here) my approach is to use my inbox itself rather than a new folder. I leave them unread and archive the other garbage. Then I go through the unreads at a scheduled time. How well does this work for me? - not great. It works well enough but maybe I should try this idea instead. The biggest challenge with any of these methods is to develop the discipline to actually schedule and keep the time to review these things.
