I think imbox is embarrassing, and I don’t like the graphic design, but it’s definitely innovative and good for them for doing something different.
But what's weird is this sense of anger at products that aren't as flexible. It's like being upset that a new restaurant opened up because they have a set menu and don't let you make your own food. If you like cooking your own meals, great! Keep doing that. This restaurant is for people that want someone else to make a meal for them.
With slack I understand the frustration a little more, since it's something an entire company is going to be using and asking you to use.
It's like operating systems. People who want to have it their very specific way use Linux. People who want it to just work out of the box use macOS (but not Catalina).
There are some innovative things here but they want $99/year for it and it doesn’t support IMAP. It’s also ugly as sin and looks straight out of 2007.
The biggest hurdle is that it just won’t play nice with all of my email accounts. I would have to maintain my “normal” mail application and also maintain Hey. The benefits Hey might offer are ruined by not being able to have a consistent workflow across all of my accounts.
