On the one hand, this is an interesting approach to the problem of overflowing, unmanageable inboxes. On the other, we see a few issues with the system. One: it may come off as being a bit arrogant, making the receiver feel unimportant or not worthy of a lengthy response from you. We’re concerned using this in office environment might upset your bosses. Second: some things simply can’t be crammed into two to five sentences and constantly alternating or removing your email signature might become annoying. Lastly, we believe that constantly minimizing your dialogue in a conversation will just lead to more questions from your confused recipient. This means you're ultimately sending and receiving more emails than you would have had you sent a normal length response in the first place.
That being said, we are always interested in hearing new and interesting ideas to reduce email clutter — don't think we like to shoot down all creative answers. We want to know: has anyone been able to apply this method successfully? Are you a master of language, compacting even the most complex thoughts within three or four sentences? If not, here are other ways to help combat that pesky email.
