This doesn't sound like an 'email killer' to me, and I'm quite sure this functionality exists elsewhere (I'm sure I've seen it, not sure where).

I'm REALLY most confused as to why you think this is an 'email killer'. You're using email, how can you kill what you are using?

If you are trying to kill email, you need to understand the problem with email. Is the problem that email doesn't integrate with other systems (which it seems you are somewhat suggesting)? No. Clearly, email integrates with systems too easily, it is a no brainer.

Before you go touting that you are building an email killer, I suggest you deep dive into why email needs to die.

@pedalpete sure, it's not that in the exact sense. But surely an 'email client killer' in another sense.

Yes there are teams working in this direction notably Front (https://frontapp.com/ - they raised an investment from Slack's founder) and Fleep (https://fleep.io/). But we have taken a different approach to it, according to the problems we faced.

Taking the views of community specifically on this particular approach.

Sorry to disagree, but I don't see where you're going that you think you're an 'email client killer'. Again, I would still need an email client for everything outside of comptify.

Neither of the apps you pointed to suggest they are killing email or email clients.

I'd suggest that if you're going to be a collaboration tool, focus on that. Note that Fleep is a messaging platform and front seems to be organized group emails. Neither of these guys are claiming to be a collaboration app.

What are you trying to do? Figure that out, and do it. But only one thing, or else the market is going to get confused as to what they are supposed to use your product for.
