You are either on a platform or you aren’t. There is some compatibility between them, and mobile phones, replete with apps, make it easier to speak to people via separate channels, but they are not like email. There is no single portal. You are on Slack for work, WhatsApp for your personal private chats, and perhaps Facebook messenger or Snapchat for something else. To some extent, they all offer a level of security that email does not provide, but (so far) they have not replaced it. And, unless the corporate owners of each of these new platforms agree to coordinate somehow to mimic the all-access pass of email, they probably won’t.
We will never escape email

Have you tried out Redkix? We just launched and essentially solved this problem for the workforce. Would love to hear what you think.
