Ask HN: Set up different email address for 'meaningful' personal correspondence?

I was reading Jay Caspian King in the New York Times today ("Email Is Slow and Creates Distance. That’s Why It’s Great")[1]. The piece is about when email was used more often for lengthy personal correspondence (i.e., writing 'letters'). I came across this paragraph:

""" I have one piece of advice for anyone who wants to return to the old days of email: Set up a separate account for all of your lengthy correspondences and check it about once every two or three days. This, more or less, is the relationship I have with the emails I receive from the readers of this newsletter. As I mentioned in last week’s edition, my reader email address has resulted in dozens of meaningful exchanges, the sort of stuff I rarely find on social media """

Does anyone do anything like this? How did it work?
