Paced email is surprisingly handy for me. I did not expect to gain much from it, but it turned out that I saved decent amount of time with the helpful "paced summaries". By setting scheduled time to receive e-mail batches, it really helps to set a discipline for myself and therefore be more productive (I can save the best energy in the day for the works I want to do).

All in all, Paced email is surprisingly handy and useful for me.
