Slack’s intuitive interface and smooth integrations have made it an indispensable part of our day-to-day workflow. The ability to connect apps like Google Drive, Jira, and GitHub directly within our channels significantly cuts down on context switching and keeps everything in one place. I also really value the threading feature, since it helps keep individual conversations organized without cluttering the main channel view. Review collected by and hosted on G2.com.

The biggest downside is the pricing structure for smaller or growing teams. On the free tier, the limited message history is a major pain point because you lose access to past decisions and shared files. Upgrading does address this issue, but the per-user cost can become expensive quickly as your organization scales, which ultimately hurts the overall ROI for smaller businesses.

Honestly, the channel organization is what keeps things from falling apart. I manage a data team and we have separate channels for different stuff—pipelines, incidents, general discussion, and specific projects. Before Slack, we were doing all this over email and it was impossible to find anything. Now when something breaks, I know exactly where to look. Someone messages #incidents and everyone relevant sees it immediately. It's not fancy, but it just works.

The search is actually useful in ways that surprised me. We're constantly dealing with questions that have been asked before. A business user will ask "why did revenue drop last quarter?" and instead of explaining again, I can search for that conversation from months ago and share what we found. We've probably saved a month of repeated explanations because I can pull up old threads instead of re-answering the same questions. That matters when you're supporting multiple teams asking similar questions on different timelines.

The threading keeps conversations somewhat readable. We'll have 20+ messages discussing a data quality issue—what went wrong, how we're fixing it, what we found. If it wasn't threaded, the main channel would just be chaos with ten different conversations happening at once. The thread keeps it contained so people can follow the discussion without getting lost.

I like that it's accessible. Everyone on my team uses it. There's not a learning curve. You open Slack, you know what to do. Compared to some other tools we've tried, it doesn't require a manual or training. That sounds basic, but when you're trying to keep a team aligned, tools that are just intuitive to use matter.

The notifications are fine. I can mute conversations I don't need to watch and set up alerts for keywords that matter to me. I get notified for mentions and direct messages, which is enough. I'm not drowning in notifications constantly, which is better than how email used to work.

One thing that does frustrate me is the search could be better. Sometimes I'm looking for a conversation from specific months ago and it takes a while to find it. The search results aren't always organized the way I'd expect. And honestly, Slack keeps changing the UI and it gets annoying relearning where things are. But that's minor compared to how much we rely on it daily.

The file sharing works. People upload data documentation, query results, screenshots of broken dashboards. It's all there in the conversation thread so context is preserved. Way better than email attachments getting lost.

Slack is just reliable. I can't remember the last time it was down or buggy for us. It's not going to blow your mind with features, but it does what it's supposed to do without causing headaches. For a data team that needs to coordinate quickly and reference past decisions, that's enough. Review collected by and hosted on G2.com.

The notification system drives me crazy. I've spent way too much time trying to configure notifications so I'm alerted about what matters but not bombarded with everything. I've got messages from five different channels, direct messages, mentions, keywords I've set up, and Slack keeps changing how notifications work. I end up either getting too many notifications and missing the important ones in the noise, or I turn things off and miss critical alerts. There's no sweet spot. The notification settings are buried in menus and it takes forever to actually tweak them the way you want.

Threads are supposed to fix conversations getting messy, but they create a different problem. If you reply in a thread, most of your team won't see it unless they specifically click into that thread. So important information ends up hidden away, and then people ask the same questions again because they didn't realize there was an answer in a thread. I've had to tell my team multiple times to mention someone directly in the main channel if it's important, which defeats the purpose of threads.

The search is unreliable for finding older conversations. Our Slack workspace is three years old and conversations from year one are hard to find. The search results don't always show what you're looking for, and sometimes you have to try different keywords just to get relevant results. When I need to reference something from a year ago, it's frustrating how long it takes to dig it up.

The UI keeps changing. Every few months Slack redesigns something or moves features around. I'll be looking for a setting and it's suddenly somewhere else. I get it—companies update software—but the changes feel unnecessary most of the time. It's just friction when you're trying to work.

Slack can be slow sometimes, especially when we have heavy file sharing happening or lots of people posting simultaneously. The mobile app especially gets sluggish. Not constantly, but often enough that I notice it and it's frustrating.

The external sharing features are clunky. When we need to collaborate with people outside our organization, the setup is awkward. It works, but it feels like a second-class feature compared to how internal communication works. Review collected by and hosted on G2.com.

I like many good features of Slack that go beyond the expected communication. I like both individual communication and group communication, as well as screen recording, message summarization in threads to save time, and highlighting words that I choose myself. Additionally, I highly value the app on the phone. I also appreciate the easy integration with tools like Jira, Mural, Amplitude, and Aha, as well as the agile communication in daily life, the use of threads, the existence of permanent and temporary groups, and the simpler and facilitated sending of contacts.

I think that messages from threads, channels, and groups end up getting a bit lost, depending on the flow I follow in the app. Sometimes, my intention is to find a specific group and, unintentionally, I end up marking things as read in other groups that weren't what I wanted. It also happens that I don't see relevant messages within the threads; it's a lot of information concentrated in one place, and I still haven't found better ways to prioritize what is most important.

I love how easy it is to keep everything—and everyone—in check. The UI is very easy to navigate, and it helps a lot that it integrates with Notion so our entire team can stay on the same page. It never lags, and we haven’t experienced any downtime. It also helps us keep all the supporting docs and SOPs in one place.

One thing we’ve used extensively is their slackbot Ai. It’s incredible at learning from context and drafting great responses based on that context. Support has been okay, mainly because we haven’t run into any issues. The team pricing is spot on as well. Onboarding is straightforward and doesn’t require any hand-holding.

The activity tab, I think its a little cluttered and can get confusing Review collected by and hosted on G2.com.

I used Slack regularly for my daily official work, and it's become one of my favorite app for communication, collaborations and project execution.

It's UI/UX is very clean, making it easy for new members to get started without much training.

Performance is reliable and integrations with tools like Jira, Teams and other keeps workflows centralized.

Pricing is also good with much premium features.

AI-powered capabilities help spped up documentation and other work preparation. Review collected by and hosted on G2.com.

It's although a good platform but there are a few areas where it could improve like searching older discussions sometimes requires precise keywords and also in free plan it has limitation of 90 days conversation view.

Also the free plan's limitations can also be very restrictive for smaller teams. Review collected by and hosted on G2.com.

The best part of Slack is its ability to replace endless email threads with real-time, organized communication via channels. The integrations and search capabilities make it an indispensable command center for my daily workflow Review collected by and hosted on G2.com.

The biggest downside for me is notification overload and the constant pressure to stay 'always on.' With multiple active channels and DMs, it's easy to get pulled into distracting side conversations that fragment deep work time. The search function, while powerful, often returns too many irrelevant results, making it tedious to pinpoint that one specific message from weeks ago. Additionally, threaded replies can sometimes bury critical updates, so if you miss a thread, you might completely lose the context of a decision. Lastly, the pricing scales steeply for larger teams, especially when you need unlimited message history, which feels restrictive for growing companies. Review collected by and hosted on G2.com.

What I like most is how it keeps team communication organized. Instead of getting stuck in long email chains, conversations stay in dedicated channels, which makes it much easier to track discussions tied to a specific project, release, or production issue. Even if I miss messages during the day, I can catch up quickly without having to ask everyone for updates.

I use it every day to coordinate with developers, testers, and product teams. Sharing screenshots, log files, code snippets, and links is straightforward, and the search feature helps me find older conversations when I need to revisit an issue or confirm a decision. That’s saved me a lot of time on more than one occasion.

It also integrates well with tools like Jira, GitHub, and Google Drive, so important notifications and updates land in one place instead of being scattered across different apps. The interface feels clean, notifications are easy to manage, and it’s available on both desktop and mobile, which makes staying connected really convenient.

Overall, it’s become one of those tools I keep open throughout the workday. It helps the team communicate faster, keeps discussions structured, and makes collaboration feel smoother. Review collected by and hosted on G2.com.

There isn’t much I dislike, but there are a few areas that could be improved. In busy workspaces with lots of channels, it’s easy to miss important messages when several conversations are happening at the same time. I also think notifications need a bit of tuning when joining a new workspace; otherwise, they can quickly become overwhelming.

Search works well most of the time, but tracking down a specific message from months ago can sometimes take a few tries if I don’t remember the exact wording. I’ve also noticed that the free version limits message history, which can be inconvenient for smaller teams.

Aside from those minor points, it’s been reliable and easy to use. The advantages of faster communication and better collaboration still outweigh these small drawbacks. Review collected by and hosted on G2.com.

I use Slack daily to connect with my support team, team leads, quality team and agents. Few things I like most:

- Channels keep communication organized by team and topic, no information gets mixed up

- Sharing audit reports, score sheets and files instantly without switching to mail

- Tag specific people with @ mention for urgent issues, right person gets notified immediately

- Real time messaging makes resolving issues much faster than email

- Huddle feature allows quick voice calls without any extra setup during escalations

- Search helps find old messages, reports or files shared weeks ago in seconds Review collected by and hosted on G2.com.

No big dislikes, but notification overload can be a bit distracting during busy hours, better notification management options would be helpful. Review collected by and hosted on G2.com.

I use Slack for internal communication in the studio and as the notification center for all apps. I appreciate how it gathers all messages and notifications in one place, providing a very centralized experience. I really like that it's easily connected to other apps and lets me use it as a notification hub. It's great that it takes a wide range of formats for sharing purposes. With Slack, I don't have to open Ayon to know I have a notification or someone mentioned me, and I can share files with my team easily. I also enjoy having the mobile app mirror everything, and I appreciate that it updates my status if I'm in a meeting on its own. The integration with tools like Miro, Ayon, Render Farm, and Google Calendar is very useful for me, and the initial setup was very easy. Review collected by and hosted on G2.com.

The search is weird, very strange; I need to be smarter when I search for someone's name. Also, the way it arranges the contacts on the left is very random. They should be arranged by frequently contacted person, or at least give the user the option to arrange chats the way they like. Review collected by and hosted on G2.com.

What I value most about Slack is the centralization of communication in one place. The organization by channels and the use of threads keep discussions organized without cluttering the main flow, which makes a big difference in day-to-day service.

The interface is intuitive and fluid, with a low learning curve — within a few days I was already using the main features without formal training. The integration with other tools in the stack, like Google Workspace, works well and avoids constant switching between platforms.

The internal search was an unexpected benefit: retrieving messages and files from months ago is simple and fast. AI features, like channel summaries, also help keep up with conversations without having to scroll through hours of history.

Overall, Slack delivers a good return: it saves time, organizes communication, and increases team productivity. Review collected by and hosted on G2.com.

One of the main areas for improvement is the system's resource consumption. Slack can become heavy with many channels and workspaces open simultaneously, which impacts the computer's performance, especially on machines with more modest configurations.

Notification management, although configurable, can still be smarter. On days with a high volume of messages, it's easy to get lost or end up muting important channels due to overload — a more refined prioritization system would help a lot.

Advanced search also has room to evolve. More precise filters by date, file type, or sender would make information retrieval even more efficient.

Finally, the message history limit on free plans is quite restrictive and can be frustrating for teams that rely on access to history for consultations and audits. Review collected by and hosted on G2.com.
