The most valuable features are the ability to communicate instantly and create channels. I want to notify users of messages that need immediate ​attention.

What is most valuable?

The most valuable features are the ability to communicate instantly and create channels. I can create a channel called #breakfastdiscussion, invite three people on my team, and we can chat over breakfast. I can also make a channel called #teamtalk and all the team can be invited. This is a great feature.

How has it helped my organization?

We can group conversations around different issues. The issues are entirely created by us, in-house. It works well for a small team with opt-in members.

What needs improvement?

I would like to be able to notify users that they have messages that need their immediate attention. If Slack picked up more features of Asana, such as ticketing and calendars and assignments, I would give it a rating of 5/5.

For how long have I used the solution?

I have been using Slack for a year and a half.

The valuable features are group chat, sharing of attachments, and pinning items.

What is most valuable?

The valuable features are mainly group chat, calling, easy sharing of attachments, and pinning items. These might be basic features, but they make life much easier.

How has it helped my organization?

Communication with clients became easy. Different groups for different teams helped a lot in the planning and execution. Everyone stays updated with the progress without any ambiguity.

What needs improvement?

I believe they can improve upon ‘calling’, which was introduced recently.

For how long have I used the solution?

I have been using this solution for more than a year.

What do I think about the stability of the solution?

There were not many issues with stability, but whenever they introduced a new update, the loading time went up.

What do I think about the scalability of the solution?

There were no issues with scalability.

How are customer service and technical support?

Technical support is good. They are pretty quick with responses and provide excellent support.

Which solution did I use previously and why did I switch?

We were using Skype. We switched mainly because maintaining different client organizations is pretty easy on Slack.

Other reasons include the powerful search feature, rich messaging, a more customizable interface, chat functionality, and email notifications.

How was the initial setup?

The setup was pretty simple and quick. The sign up form was easy and the complete onboarding process was quite smooth.

What's my experience with pricing, setup cost, and licensing?

Slack is actually rewriting the rules on SaaS pricing. It’s free for basic use and offers some awesome features at no cost at all. I will highly recommend Slack to other companies.

Which other solutions did I evaluate?

We didn’t look at other alternatives.

What other advice do I have?

I am not sure if someone is looking to implement a product like Slack, but if someone is really looking for it, then it’s not that easy.

Slack took many months/years to get to this stage. More importantly, they focused on small and medium sized enterprises, which was their biggest market.

The most valuable features are creating chats with combinations of people and the remind function.

What is most valuable?

Creating chats with any combination of people and the remind function.

How has it helped my organization?

We've been using it almost from the very start. It has helped us keep communication open between our international offices.

What needs improvement?

There are a lot of features in Slack that I don't use, because I don't know about them. I found the remind feature when I Googled the Pomodoro technique. I found this by chance. It would be helpful if Slackbot gave me some tips on features that I don't currently use.

For how long have I used the solution?

We have been using the solution for more than two years.

What do I think about the stability of the solution?

I did not encounter any issues with stability.

What do I think about the scalability of the solution?

I did not encounter any issues with scalability.

How are customer service and technical support?

I appreciate the ability to create multiple private or open channels.

What is most valuable?

I appreciate the ability to create multiple private or open channels.

How has it helped my organization?

  • The ability to create ad hoc channels for certain projects has made us more effective.
  • The mobile app allows us to communicate on the go, which saves time as well.
  • Onboarding new users is easy thanks to Slack's great UI.

What needs improvement?

There seems to be several minutes of delay between getting notifications on the Mac OS app and then receiving them on the iPhone app.

For how long have I used the solution?

I’ve been using Slack for over a year.

What do I think about the stability of the solution?

We haven't really had any stability issues.

How are customer service and technical support?

The product works very well. I haven't personally had the need to contact Slack's support. I did have a question about using Slack several months ago which I posted on Twitter. Their Twitter support team was very responsive and helpful.

Which solution did I use previously and why did I switch?

We used Skype before Slack. We switched because Slack offered:

  • The ability to create multiple channels
  • A more user friendly interface
  • The ability to keep us more organized and effective

What's my experience with pricing, setup cost, and licensing?

I would recommend considering staying on the free version. It does limit you in terms of the history of communication and storage, but I think that these problems can be worth overcoming. This is the case especially if you are a smaller team or a startup that needs to watch where you spend your dollars.

Which other solutions did I evaluate?

We decided to just test Slack out first with no intentions to switch from Skype. However, the whole team fell in love with the product. At this current moment, we are experimenting with Workplace though.

What other advice do I have?

Once you sign up, try keeping things clean by creating multiple channels. This will ensure that individual conversations are relevant and that the team does not get distracted by unnecessary chatter.

The ability to create separate channels is valuable.

What is most valuable?

The ability to create separate channels is valuable.

How has it helped my organization?

For projects, it's improved how we share files. The Google Drive extension means that files can be housed right inside of Slack. We can focus on work without distractions.

What needs improvement?

Microsoft and Google are creating competitive equivalents. Slack needs to find a "secret sauce" that can differentiate them further.

For how long have I used the solution?

I have used Slack on and off for the past few years. I use it with some side projects.

What do I think about the stability of the solution?

We have not had any stability issues.

What do I think about the scalability of the solution?

We have not had any scalability issues.

Which solution did I use previously and why did I switch?

We did not have a previous solution.

How was the initial setup?

The initial installation was not at all complex. It was very WYSIWYG.

What's my experience with pricing, setup cost, and licensing?

I use the free version.

Which other solutions did I evaluate?

We did not evaluate any alternatives.

What other advice do I have?

It comes right out of the box. Start exploring!

The most valuable features are direct messaging and having conversations in channels.

What is most valuable?

Direct messaging and having conversations in channels. I love the channels feature, because it allows you to sort conversations. The only people who will see those conversations are people who are interested in that channel or are part of that initiative/project.

How has it helped my organization?

We have slashed our internal emails by 30% and streamlined the tools we use for instant messaging.

What needs improvement?

The profile feature needs improvement. There is little room to add details to this section. It would be nice to be able to add more links or have other ways to connect in this section.

The ability to flesh out the Profile section in Slack by including links
to multiple social channels, a beefier bio and a link to a website would
be helpful for communities using Slack. This feature may not be as
necessary for teams using Slack as an internal communication tool, but
it would encourage them to follow each on other social channels and
potentially spark more engagement across channels.


For how long have I used the solution?

I have been using Slack for just over a year.

What do I think about the stability of the solution?

We have not had stability problems.

What do I think about the scalability of the solution?

We did have scalability issues. If you are on the free plan, you are only allowed 10,000 messages before everything is archived. This is a big problem for an alumni group which I am a member of that uses Slack.

Our messages are archived every two weeks, which makes it challenging to search for former conversations.

The price of using Slack would be $30,000/year for that community, which I think is quite steep.

How are customer service and technical support?

I've never used technical support.

Which solution did I use previously and why did I switch?

I used Skype for instant messaging and LinkedIn/Facebook groups for community engagement. Skype is clunky and has an outdate user interface.

Slack is slick, smooth, and easy on the eyes.

LinkedIn/Facebook groups are cluttered and distracting. It's too easy for an "oh, shiny" moment to happen on those social platforms.

How was the initial setup?

The setup was straightforward. Slack is great about walking you through the process of setting up channels and inviting people to join.

What's my experience with pricing, setup cost, and licensing?

Stay on the free version and use PaperBot in every Slack channel to "archive" conversations. This helps you work around the problem with 10,000 messages.

Which other solutions did I evaluate?

We looked at Skype for instant messaging and Discourse for community engagement.

What other advice do I have?

If you're looking for an asynchronous/real-time communications tool, you will not find any app that comes close to Slack.

The most valuable feature is the ability to be a part of multiple Slack channels that are specific to our needs.

What is most valuable?

The feature that is most valuable is the ability to be a part of multiple Slack channels that are all specific to our needs i.e. a product, infrastructure, personal one-on-one, small specific group, feature discussion, IT assistance, company announcements, etc.

How has it helped my organization?

The quick line of communication, most certainly improves the functionality of our organization. Discussions can happen at the drop of a hat, in a Slack channel and a critical decision can be agreed upon to take further action. Triage of customer issues can happen at the moment of crisis and this is of huge assistance as to how we can get our product back up and running, when needed.

What needs improvement?

I'd like the ability to re-organize the channels in my list. You can favorite a channel but you can't organize them in a specific order, that fits your every day use. I'd also improve it's security. It can be breached easier than an email client, so we tend to keep more confidential conversations out of the app.

For how long have I used the solution?

I have personally used this solution for over two years.

What do I think about the stability of the solution?

Our Slack bots have issues from time to time. There have been a few times where the app was done but other than that, it has been a solid performer.

What do I think about the scalability of the solution?

There were no issues with the scalability.

How are customer service and technical support?

I have personally not used technical support for Slack.

Which solution did I use previously and why did I switch?

We were using Gchat as a source to speak to each other but channel functionality is very important in Slack.

How was the initial setup?

I was not part of the initial setup.

Which other solutions did I evaluate?

I am sure that other options were evaluated but I was not a part of that decision-making process.

What other advice do I have?

Providing API connections to your bug database and any other database that you use, can give you updates and links inside of a channel, which is a huge help.
