Except convenient features connected with creating channels that can have different purposes and can be created for different projects, slack offers creating special channels and inviting your customers to join conversations.  And this is perfect as you can get stats easily and reports on clients who contact you more often and topics that they are interested the most.

One of the most big advantages for slack – is it’s stats section. You can analyze with it:

  • total number of messages sent
  • messages sent in channels and direct ones
  • space storage
  • apps and integrations enabled
  • messages and files posted by each member

Moreover, you can manage rights of people who can view statistics and team preferences and assign default channels for each new member, thus they will see where to start.

Slack Disadvantages


Although slack is very convenient and commonly used tool, one of the greatest it’s inconveniences is problems with connection. Mobilunity team unfortunately faced few issues where slack was constantly losing connection. We figured the issue out with adding Slack to white-list in our firewall.


Still many users informed that notifications sent by slack are very inconvenient for Mac users. New messages are shown with small red dot and it prevents immediate reply on the user’s side.

Slack bot

Controversial and unusual way of Slack to new users as bot writing messages and informing about Slack’s features and system is not canned one, but a bit weird. For sure this depends on user if he is ok to talk to a machine other than to read manual or ask live.


Pricing model is quite simple having own pros and cons. Slack does offer you a free plan with 5Gb of free storage per user and 10 integrations – which is quite good offer! But it doesn’t mean that you may not use other resources as email account, and another project management tools (as Jira or Redmine). In case you do not want to create company email address and need to have more space and connections you can go to Standard and Plus pricing models  with $6.67 and $12.50 per user. We suppose that if you are in need of bigger amount of virtual space or integrations this may be quite not cheap for your budget.

To sum up check slack’s disadvantageous:

  • Connectivity problems
  • Inconvenient notifications
  • Slack bot for new user experience
  • Pricing

We hope that our comparison table with Slack’s Pros and Cons will be handy for you:
