Performance of Slack Across Market Features

Slack Likes & Dislikes

The Scalability and reliable performance, and a wide range of cloud services that support AI, data, and application deployment efficiently.

Slack is incredibly easy to use. The drop in drop out, click once type of mentality is fantastic to use

Dynamism and interaction between groups.

Automated Translation from Portuguese

Coast Management and configuration of some advanced services can be complex to new users.

- hard to customize to explicit company brands across the entire platform - When there is an error, it can be hard to troubleshoot from a IT point of view. - Doesn't have as many options for screen share / collaboration offers as other platforms

I think the excessive number of messages can cause important issues to get lost; I got a little lost in the interface and sometimes had difficulty setting up routines.

What Your Peers Are Saying About Slack

VP of IT

I am revisiting our messaging retention thresholds more specifically for email (Google) and instant messaging (Slack). Was curious as to what is generally being used as the threshold for these 2 communications tools (i.e.; 30 days, 6 months, etc.)?

Director of IT

I also am curious what other organizations are doing on this front. We had an event where legal had us put an indefinite hold on all messages (email, IM, etc) and now that has just become the standard. Would like to compare what other organizations are doing and try to get us back to something that doesn't hold messages forever.

VP SALES OPERATIONS & ENABLEMENT

Does anyone have experience with Slack Sales Elevate or Slack AI? If so, did you see any productivity improvements, specifically for Sales? We are looking at Sales Elevate for a few specific use cases: (1) Deal Desk efficency improvements; (2) Summaries of changes made to opportunities for sales leaders; (3) Account planning (there are collaborative templates in Sales Elevate which you can configure to meet your org's needs). We're also interested because it seems like an easy way to start using AI in a fairly low risk area. For context, we use SFDC CRM already.

Been disappointed by it honestly, especially when compared to Momentum.io it doesn’t even come close.
