Slack

A single place for team communication and workflows

4.6/5 (16085 reviews)

Slack Overview

Teams in Slack work together in channels that can be organized by project, department, office location, or anything else, really. This makes it easy for users to follow the topics that are important to them. Public channels are open to anyone on the team so marketing can see what designers are working on, sales can see what’s on the product team’s roadmap, and new hires can easily get up to speed instead of starting with an empty email inbox.

Slack connects to the tools and services that businesses already use and centralizes the notifications, files, and data from hundreds of different applications. This means no more searching through emails for that one follow-up, constantly switching between different tabs and dashboards, or juggling dozens of tools - each with their own login. Slack helps teams work smarter by providing all of the information and context needed to make effective decisions quickly.

Everything shared in Slack is automatically indexed and archived so that companies can create a comprehensive knowledge base with zero effort, simply by working in Slack. And, Slack’s search makes it easy find the information users need, whenever they need it.

Great team messaging application

Review Source: Capterra

Overall experience has been great. All the features work as intended. We have never had people miss notifications, fail to send attachments, not able to logon etc... All issues we have had with MS Teams.

Pros

It is very easy to use. Appealing graphical interface. Many integrations with other apps. Easy to use features. Shortcuts make work quick, as well as the slash commands. Easy to navigate, create channels (public or private) and customize for your team.

Cons

The cost is high. Our company has the paid version of slack, which is a great product. However, since we are using O365, teams is included for *free*. It was hard to justify keeping Slack as a paid product when we have another solution available. Keep in mind, teams is a sub par replacement.

Wether Slack is an advantage to your internal communication and productivity depends entirely on the pre-existing culture and the amount of self-discipline and thought your employees can provide. It's crucial to establish communication on the rules for using Slack in order to avoid wasting time.

Pros

The openness of Slack for plugins and useful integrations is awesome. You could easily employ one person just to optimize workflows, channels etc in Slack for a company with some hundred employees: that's the amount of possibilities. Also, Slack is a way of promoting the exchange of information and establishing personal relationships among employees.

Cons

In the worst case, Slack is a tool that places you at the disposal of each of your colleagues, at each moment of your day. Slack fosters a culture of deflection by communicating all the time and sharing more or less useful content with a far too high number of people.

Slack Review

Amazing. We have a team the works remote and using Slack is a lifesaver. As offices modernize, it's hard to just go to someone's desk to ask a question. Leaving a Slack message is much less invasive an easily searchable paper trail in case you need to reference it later.

Pros

Slack is great for teams and personal life communication. The amount of categorizing and partitioning you can do within a workspace is astounding. You can utilize certain project hashtags when speaking about it, then later go in search the hashtag to find all messages about said project. Different channels can be set up for various teams/ clients/ projects and the number of 3rd party integrations are immense. For instance, I can create a task in my TSM "Wrike" instantly from a Slack message making things super easy as messages are flying past.

Cons

There's not much to complain about here. The Chat bot can get a little annoying if you already know what you're doing. Also, if your friends/ family use Slack for a group chat, it can be difficult to separate work/ personal life as all of your spaces are in one place and you can see you have work messages.

Slack: a good business instant message application

Used Daily for 1+ year

My experience with Slack has been really good.
Slack helps me a lot on my daily activities and even more when I'm working from a remote location or inspecting something and need to interact with our team at the main office.

Pros

Slack is easy to use and its interface is very similar to other IM applications we have been using for years.
That makes the transition from whatever IM software currently in use to Slack quick and smooth.
In our company, nobody needed to be trained to use Slack and users went well with the transition process.
Slack allows users to customize their names, profile picture, and current status.
It's also possible to send messages to individuals, groups of people, and into channels.
Users most commonly send text messages but they have the option to send screen captures, pictures, and files in general at their own convenience.
A very useful resource in my opinion is the ability to create shared channels where you can add people from outside your organization as well as users from other Slack organizations.
With this feature, you can create a support channel with a service provider and have quick interaction with them, for example.

Cons

I don't have too much complaints about Slack.
One of them is that as an Administrator, I believe that the management interface is a bit confusing.
Sometimes it takes me a while to remember certain basic operations because Slack has its own way of having that done.
Also, I had issues with some of my users a couple of times because of bugs with Slack application.
The last I remember would freeze half of the user's screen so nothing shown in that area was clickable of selectable.
Closing and reopening Slack would temporarily solve the problem.
I contacted Slack support and they confirmed that as a known issue and that would be fixed soon with a software update.

Ended internal email overload in one day!

Used Daily for 2+ years
Reviewed on 06/11/2019
Review Source: Capterra

Making progress on internal discussions can start in seconds with a Slack group chat. It is hard to imagine a way of managing teams in different countries any other way. Slack removed a reliance on internal emails which often fell short where key people weren't copied in or involved in the discussion. In a similar way, it avoids the CC happy emails where some team members may not need to be included and is an unnecessary distraction. With public channels, anyone can decide if they continue to remain invovled or just choose to 'mute' a channel, even just for a period of time.

After using it for over 2 years now, the results are that people in our organisation can manage their communication and let it fit in their workflow. With various integrations it can also be a real timesaver when on the move.

Pros

The options of private/direct group conversations and public and private channels make the various types of cross-team communication most companies need so simple that it's hard to remember how we got anywhere when relying on email.

As a personal favourite feature, the option to upload custom emojis makes messaging easier, not just for fun but in the cases where logos/symbols can be easily understood by everyone, it makes quick shorthand.

Cons

Someone who reccomended this product did warn to be careful that it may take over our lives, and they weren't wrong! Through no fault of Slack , the ease of adding channels, setting up groups etc does admittedly add to the noise that can sometimes be a distraction.

The Slack call quality can sometimes be unreliable and audio quality isn't amazing.

Benefits

Slack surveyed thousands of Team Owners and Admins to see how Slack helps their teams work. The average team using Slack sees:

  • A 32% increase in productivity.

  • A 48.6% reduction in internal email.

  • A 25.1% reduction in meetings.

  • And, 80.4% agree Slack has increased transparency on their team.

    These findings have both tangible and intangible benefits for any business. Fewer meetings, reply-all email threads, and lengthy conference calls means teams can work smarter and be more productive. Additionally, this helps teams feel more connected and engaged at work.

  • GetApp Analysis

    Email, voicemail, instant messages, text messages, and phone calls are just a few of the ways that busy teams communicate, but manually checking and responding to the messages coming from so many platforms consumes far too many resources for today’s busy teams. Slack is a cloud-based solution that replaces traditional forms of messaging, and brings all group communication together in one place.

    Designed for businesses of all sizes, Slack is frequently used by leading technology companies such as BuzzFeed, Salesforce, Spotify, and eBay. Top features include real-time messaging, drag-and-drop file sharing, automatic indexing, and integration with hundreds of popular business apps. Slack offers its own native apps for iOS and Android, which means users are able to stay updated whether they’re working inside or outside the office.

    Browsing Channels

    What is Slack?

    Slack is a real-time communication platform designed for teams. The cloud-based solution brings group communication together into a centralized environment and replaces long email threads and status update meetings. Conversations are automatically indexed and archived, which enables users to pull up past files—including PDFs and Google documents—regardless of how long ago those files were shared and discussed. Slack searches within files, and it also allows users to share documents with virtually anyone.

    In addition to its powerful messaging and document sharing capabilities, Slack also serves as a hub for integrated business apps. Organizations are able to integrate many of the tools they use every day with their Slack accounts. Pulling this data into a single platform saves time and increases efficiency for busy teams.

    Switching Between Teams

    Slack Main Features

    Real-time messaging

    Slack is best-known as a real-time messaging platform for teams. In addition to facilitating open conversations between groups of people, Slack also offers the ability to conduct private conversations in a one-on-on setting and within smaller sub-groups. (These sub-groups are ideal for handling more sensitive topics that may not apply to everyone in the company.)

    Login to Slack to start participating in a group conversation. These conversations will replace lengthy email threads, and they enable you to work more quickly when communicating with large groups of people. Use the @mention feature to tag a specific colleague within the context of a larger conversation, or add an emoji to demonstrate how you’re feeling at the time when a message is sent.

    Messaging

    Team channels

    Communication within Slack is divided up into channels, private groups, and direct messages. Channels are the place where open conversations take place. These conversations are easily archived and searchable.

    Anyone can join a channel, including team owners, admins, and regular users. However, you do have the option to prevent users with restricted access and single-channel guests from searching specific channels. Clicking on the information icon for each channel pulls up information about that channel’s purpose, along with the ability to add other users and browse shared files. The information icon is also what you’d select to leave any channel.

    Adding Channels

    Drag-and-drop file sharing

    Slack has developed a method for quickly sharing files of all types. Users can drag-and-drop files from their computers, or the cloud, directly into Slack. Slack supports PDFs, images, and videos, along with many other types of files.

    Once you’ve shared a document with your colleagues, get ready for the feedback. With Slack, your colleagues can comment on the file you’ve shared. These internal discussions can take place through the comments section. You can also add stars to the documents your colleagues have uploaded to mark which files you’d like to keep handy for future reference.

    Uploading Files

    Indexing and archiving

    Slack automatically indexes and archives everything that goes on within a team’s account. This includes all messages, notifications, and files. Slack also indexes the content of every document that’s uploaded, which means users can search for keywords contained in specific PDFs or Word documents.

    When you use Slack, you don’t have to worry about accidentally losing track of an important file, even after the group discussing that file has been disbanded. Private groups can be archived or closed after they’ve served their purpose. Archiving a group removes it from the list of available groups, but keeps all data secure for future reference.

    Archiving a Channel

    Contextual search

    The search features in most email platforms are not robust enough to handle the needs of growing organizations, which is why Slack has developed its own contextual search tools. Users are able to search for keywords across entire team archives, or within specific documents, images, and other files.

    In cases where the one thing you remember about a particular file is a generic keyword, you can use Slack’s filtering tools to dig deeper into the archives and pinpoint whatever it is you need. Search results can be filtered by date range, relevancy, and person, along with many other factors.

    Deep Search

    Slack Integrations

    Integrations are a major part of Slack’s platform. Slack integrates with virtually every major business app. Users are able to set up their apps to post notifications inside the app and bring data together into one place.

    Slack integrates with more than 80 external services, including Asana, Box, Dropbox, Desk.com, Google Drive, JIRA, and Stripe. Users with programming knowledge also have the option to create their own integrations.

    Slack Pricing

    Slack is free for teams of all sizes. Teams can use Slack for an unlimited amount of time without paying a dime. Organizations that need upgraded features, such as searchable archives with unlimited messages and unlimited external integrations, can sign up for a Standard plan at $6.67 per user, per month. Slack’s Plus plan costs $12.50 per user, per month. Enterprise plans are coming soon.
