Email is indispensable in organisations because it automatically creates a comprehensive permanent record of all communications (and optimally, one which is searchable after the employee in question has left - keep your work and personal emails separate, people!) Searching old emails for information is a core part of my workflow and has saved my bacon more times than I can count.

(Further to this - I've made it standard practice to send an email after any important phone call, summarizing the conclusions of the phone call. That way both parties have a record of what I thought we decided, and if the other party doesn't disagree then their tacit acceptance is also recorded.)

What organization do you work in? Everywhere I've worked, I've been responsible for every piece of information sent to me. Slack doesn't help at all. Conversations are based on person-to-person communications rather than ideas like an email thread with a subject line.

I have been in many different environments almost exclusively technical organizations selling tech in some form or another from tiny startups to enormous organizations, and the only time I remember anybody really caring about email was my first job at a university. I think that was mostly because IM barely existed (literally my first task was setting up an XMPP server).

So when a sales person recieved an email from a prospect they would ignore it? When a developer recieved an email about a bug in production they would ignore it? All communication was done over chat? It's not impossible, but pretty implausible.
