Slack

A single place for team communication and workflows

4.6/5 (14697 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.

Slack changes the model for business communication

Used Daily for 1+ year

Great communication tool and indispensable in the modern world of business.

Pros

It's IRC for business communication with a (much) nicer interface. Slack organizes discussions into channels and IM. It's easy to reach out to anyone in the company and have a discussion. Even better is the ability to bring in external users (customers) who can then quickly converse with support and engineering teams. For any new open source project, Slack is the preferred way to communicate with other contributors and users. Recently Slack has even added the ability to do VOIP calls through their platform. The mobile app works well and the UI is well designed to mimic the desktop app.

Slack also integrates with pretty much everything out there and it's also simple to write your own bots and plugins for Slack. For instance, we have a bot that alerts whenever someone writes to use on Intercom, as well as another that checks Stack Overflow for new messages pertaining to our project.

Finally Slack pricing is fairly competitive. There's a free tier which gives you most functionality except for the ability to search (if you exceed 10,000 messages). Then multiple paid tier options based on the number of users in your organization.

Cons

The desktop and mobile apps are my preferred way to use Slack and occasionally the performance tends to drag. Once in a while the Slack mobile app will unexpectedly terminate, although in recent updates it does that less frequently. I also don't like the fact that private conversations aren't really private as companies have the ability to request Slack for those records. I get it for compliance reasons, but be warned that private conversations are never private!

The search UI workflow isn't the most intuitive, they should just op for some universal search versus organizing the search results by type.

This is the new way to communicate online

I use Slack for daily communication business and to stay connected to coworkers and suppliers distributed among different locations. We have implemented Slack as a missing link that smoothly makes working with people on the other side of the country as if they would be sitting in an office just down the hallway.

Pros

Slack is simple, it is easy to use it has a lightweight user experience thus, at the same time is very powerful. In day to day routines it is just a great way of communicating (chatting) with coworkers. Perfect, reliable, fast asynchronous communication. Then someone tells you something you need to remember next week- use integrated reminders, that send you a message when you need it. Or you want to share your desktop real quick, to sho someone something in order to get their opinion. Slack has you covered. Or have a video call with someone or even a group of people. There you have it. Share files ? No problem. Want to have your conversations deleted after a while. there you go. The most impressive thing about all this is the simplicity and ease in which these features integrate into the core functionality which is a chat. Bravo !

Cons

Some of the features seem - behind the scenes - not optimized allready. Sharing data from my mobile device require it for example, to be uploaded first and then downloaded to the recipient. It works, but it takes more time and, I don't care when it is on the server I only care for it to reach the intended recipient(s). Synchronize it to the server whenever its suitable. Connection and reconnection gets tangled up sometimes, with Slack insisting that there is no connection available although all other applications have reconnected already. This however is complaining on a very high level, as these issues are really minor compared to almost all other platforms for online communication I have used.

Slack Public Channels improves company communication across teams.

Used Daily for 2+ years
Reviewed on 5/6/2019
Review Source: Capterra

It's a great tool, these are the key points for me:
* Improve team collaboration, shared information in a single place and all team has access to the same information.
* Reach people, sometimes you need to collaborate to make things happen, and slack does a great job at that.
* Integrate to CI/CD pipelines, we received notification about or system all time. It's better than having thousands of emails.

Pros

Public channels:
They are easy to create/configure and allow members of the company to share important information in a single place. This is really helpful for software development teams when important information is shared with other application it gets lost and there is no record of it. With the slack channel, the information is stored and can be used as references. (Developers don't have or we don't want to have time to write documentation).

1:1 Message:
What I really like is that is very easy to find people and ping them and start a conversion. Most important, you can share files, photos, URL, gifs (Very important), in a single place. Making collaboration easy and something to enjoy.

Integration:
Slack can be integrated with a lot of third parties. In my case, it's very useful to integrate with Jenkins and code versioning applications. We have implemented CI/CD and we received a slack notification with deploy information, testing information or if a system is down.

Cross-Platform:
Be able to access slack with cell-phone/desktop application is really awesome. If I don't have my computer at hand, I can keep replying messages and collaborate. Especially important when we have a critical bug, or we have to take action.

UX:
The UX is one of the best, you can start using slack with no training, it's very intuitive and easy to use. Once you start using it, you don't want to use other applications.

Cons

Conversion history:
Sometimes the conversion history is deleted after N amount of dates. Probably this is a configuration in my company, but I would like to store more information.

Re-Login:
Once in a while, you have to re-login, but what I don't like is that it logs you out without giving you a warning. It had happend before that the application logs me out, and I notice that one hour later.

The disclosure for labor communications that all work needs.

Work communication has always presented problems, the excuses range from an email that did not arrive on time, to a document with compatibility problems. Since I implemented Slack within my workspace, and in the company where I work, I have managed to fulfill the assignments that I request in record time, which has improved reception to my work within the company and in the perception of each client that asks me for a design for any advertising campaign. For any entrepreneur, Slack is a fundamental ally, because they offer you different plans that match your economic abilities, thus saving time and money in an amazing tool that has saved me a lot of headaches and allowed me to have a more fluid communication with all my work team.

Pros

One of the things that I liked most to fulfill my assistance and attention to the work teams, is the mobility that Slack offers me, I have all the power of an effective, simple and friendly platform so that my work is better. The other aspect that I liked the most, is that it is an immediate communication channel that gives me the freedom to work from anywhere, a few weeks ago I traveled out of the city and managed to attend in real time to several clients of the company for which work. Also, thanks to its wide compatibility, I have managed to use it in different operating systems, it is so nice not to have to worry about why I have made it my favorite work communication platform. In addition, you can integrate it with other tools, which strengthens all the work that I must accomplish and the scope of response for my clients and colleagues.

Cons

I have thoroughly reviewed all aspects of this great platform, and until now I have not found any negative aspects to highlight, I can safely say that in these years using its services, I have only seen improvements so I know that in the future it will be better every time.

Slack is the BEST way to communicate asynchronously

Used Daily for 2+ years
Reviewed on 4/25/2019
Review Source: Capterra

Overall, my experience with Slack has been extremely positive. It's helped my teams communicate updates faster, work more efficiently, and has increased cross-functional projects within the company. Additionally, it's a one-stop-shop for updates, conversation, and file sharing – three things essential for any high-performing team.

Pros

I work remotely for a large company, and Slack is key to making that possible. Email would just be too slow, and other chat programs don't have the functionality or breadth that Slack does. The structure built within Slack helps keep messages and ideas organized and the search feature is extremely intuitive, making it easy to search for past messages/ideas.

Slack also has functionality that helps team members express their personality asynchronously via the use of custom Slack emojis, Gif's, etc. This may seem superfluous, but for Remote employees it's a great way to recapture those in-between moments that are otherwise lost working outside of the office.

Finally, Slack has increased their plugin capacity, allowing teams to use Slack seamlessly with their existing tools. This has allowed my teams to streamline our discussions, instead of discussing in 1 place, sending files in another, etc.

Cons

Given that Slack is so easy to adopt and can quickly become invaluable to employees, I do find it strange that it's settings are hard to find in order to create the work/life balance most employees crave.

It also doesn't have an option to download conversations to create a hard-copy record (for meeting minutes, etc.).

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.

    Slack Bottom Line

    • Creates transparency within groups and teams
    • Integrates with hundreds of popular business services
    • Mobile push notifications keep users updated 24/7
