Slack

A single place for team communication and workflows

4.6/5 (15320 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.

Excellent Team Communication Program

Used Daily for 2+ years
Reviewed on 2019/07/12
Review Source: Capterra

Being in Marketing, my team and I have to send many large design files on a daily basis. During a review process of one project, we may send up to 20 files back and forth. We found that sending via email was clogging up our limited email space very quickly and it also became difficult to go through an email thread to make sure you have all the notes from different team members. So, we began searching for a communication platform that would not only allow us to send large files, but one that could also make communication easier.

We have found that with Slack! We started using Slack just over five years ago and we never looked back! The file-sharing capabilities are phenomenal. Whether you are using the desktop app, online version or mobile app, files and attachments are easily downloaded or you can view them directly in Slack.

With many of our team members working remotely, Slack has also made communication and collaboration on projects much easier. By creating different channels, we have been able to single in on specific projects. That way, communication is not lost in a long email thread. Furthermore, the search capabilities within Slack make it simple to go back in a conversation and find any past content. Slack also allows us to one-off each other, when we need a more private conversation or a direct comment needs to be made. We are also enjoying the notification and status settings.

All of us on our Marketing team would highly recommend using Slack!

Pros

Hands down, the best feature about Slack is its file-sharing capabilities. It has made our jobs easier as a Marketing team to have this in a communication platform, especially since we need to send many files on a day-to-day basis. With many of us working from home or out of the office, having a centralized communication platform where we can communicate on projects, while file-sharing, is essential. It has kept us all out of "email jail" and has streamlined our review processes and turnaround times for meeting crucial deadlines.

Cons

There is very little I dislike about Slack, but I would say that the "Threads" communication portion of Slack could be developed a bit better. With this feature, someone can reply directly to a specific comment rather than in the full channel. The only issue with this is that the thread pops up on the right side of the screen, rather than directly below the original comment. Sometimes, this can be confusing and the notifications for Threads can sometimes be overlooked. If Slack were able to open the Thread directly under the original comment/post, that would make communication and notifications less confusing.

A robust business tool that goes beyond instant messaging!

This is a tool to improve communication and collaboration. From my team's experience, we were able to pose questions to the group and discuss in real time, while keeping a record for future reference. Sharing documents in one place was simple for discussion, rather than having to wade through an entire Google Drive to find the right document name. In our company's case, Slack really did eliminate the need to have frequent project meetings.
At the time of this review, our team had not taken advantage of more advanced integrations.

Pros

Slack is simple to set up and start using on Day One. From an administrative perspective, it is simple to set up users and permission levels. New users will appreciate that the interface is fairly intuitive and customizing notifications takes just a few minutes. Advanced users will enjoy taking advantage of shortcuts, integrations with other tools and additional automation features.
The best reasons to use Slack from my experience are:
- A list of application integrations that seems to grow by the day
- Creating channels for specific projects or teams can eliminate the need to have in-person meetings
- The ability to search and review past conversations is priceless
Our team barely has barely begun to scratch the surface of all of the features included with Slack. I highly recommend using the free trial to get a feel for the software. Likewise, there is a Free version of the product that has much of the functionality of the paid version but limits the organization to 10k messages (which limits the search functionality - if you use this version I highly recommend "star"-ing or "favorite"-ing messages that you do not wish to be archived after the message limit is hit)

Cons

The cost per user license can be prohibitive for small companies or those just starting out. Although, if you weigh the functionality included with the product, you could make the case that the time saved and added efficiencies are still well worth the cost.

A great team communication tool

Slack is honestly the best tool for team collaboration. You can communicate via voice or text with your coworker or friends from the browser, desktop or phone and it's reliable a lot. The messages are there and so are the files shared. Also same with the chat rooms.

Pros

I like Slack. I have been using it for aprox 4 years now. It's simple and it get's the job done. You can add extensions like JIRA, Google Drive, DropBox and so on. Basically slack you can have different rooms for different teams (you can manage the members per room or invite) and you can also have private chat conversations with other people. It's basically a chat server for your company or organization. The mobile app is awesome, the desktop app is fine and you can also use Slack on the browser. The free tier is good if you have a small team, now if you message a lot there's like a 10,000 message limit for the history so if you want to get the best deal, you'll need to pay. Same for the file sharing, there's a limit but it works super good.

Cons

Honestly Slack is great, but with the time, it's become stagnant. A lot of other platforms are providing features that are more robust and free. For instance, Discord, even if it is for gaming, it does everything Slack does and better. Even the desktop sharing is better. I wish Slack just kind of moved out of the stagnant position they are right now and innovate a bit more or refresh their app, but hopefully they don't break it, because it works fine as well.

Slack changes the model for business communication

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.

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.

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.

    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

    • Integrates with hundreds of popular business services
