I know a lot of folks at Google and most of their (internal) communications go though email (Gmail). They absolutely hate it and understand that it's totally inadequate. They use Hangout extensively (I think it's called Meet now), but they understand that they are behind Slack or Trello as far as chat and project management goes. In order to collaborate effectively you need 1. Email 2. Videoconferencing 3. Shared workspace 4. Document management 5. CRM (if you work with clients) just to begin with. Designers need whiteboards and online proofing. Some folks need mind maps. Etc. Sorry, email and phone is not enough.
