Sounds glorious indeed! But what do you do when you need to send an email at 11:30? Do you send without looking? Or do you just wait until the next send window?

I'm genuinely interested in this because by far the most time-intensive distractor in my job is answering email. When I look at email at 9am I am usually busy replying until 10 at least. Then I get some work done which I need to send off by email at 11:30, seeing that I have 20 new emails of which 10 are somewhat relevant and 1 needs a reply.
