>30 dollars is extremely cheap There is a wide world out there where $30 is not cheap at all. I wish Americans consider stuff like that before commenting but I gave up years ago.
Sure, it has to be scaled to the market. However, even the equivalent of 30 dollars given a higher per hour rate (such as 50) is cheap. That Superhuman does not institute a region-based pricing is a different story, but you cannot deny that to Americans, 30 dollars is cheap when considering the time saved.
30/mo for email is however, not cheap or practical for many other people though.
