Product Details

What is Slack?

Slack is a Digital HQ
As the command center of the workday, Slack provides a flexible way to work with people, apps and partners in one space.

The new space for success
Slack connects people with each other and with their tools and data, equipping teams to be productive and open up opportunities.

Transform Teamwork
Working together in channels—dedicated spaces built around specific projects and initiatives—keeps the right people and information in one place.

Embrace Flexibility
Huddles let teams chat over audio instantly, with the option for video and screen sharing with the tap of a button.

Work Faster
With clips, teams can create audio, video and screen recordings to share updates, walk through demos or talk out an idea with more clarity (and personality).

Extend Collaboration
Slack Connect lets users work alongside external partners and customers in Slack channels, to speed up projects and strengthen relationships.

Integrate Tools
From project management tools to a daily calendar, Slack integrates with more than 2,400 applications.

Automate Tasks
In Slack, users can turn routine meetings and tasks like standups, approvals and requests into automated workflows.

  • Schedule messages --> In order to promote work-life balance, we can schedule messages such that they reach the recipient's inbox during the office hours
  • Entire conversation --> A new joiner to a channel has access to all the previous conversation, making it easy for Knowledge Transfer
  • Snooze notification option --> This is really helpful so that individuals don't get disturbed during the off-time or when they are in meetings/doing some important work
  • Ability to add images/videos in line and not as attachments --> makes it easier to make messages more engaging
  • Slack daily use report --> help users know how much time is spent on slack daily (digital/screen fatigue)
  • New reactions :D

  • Notification settings, I can set up notifications behavior by device; notifications runs differently on my phone than on my desktop laptop
  • Well organized threads, makes me focus on what really is important and setup the context very well
  • Reactions really simplifies people response
  • Formatting options, I would like I have better access to format my messages
  • Speaker camera would be great, sometimes it is needed so we need to go to meet

  • Organized way of having conversations and sub conversations through Slack thread
  • helps in setting reminder notifications and multiple communication types: voice/text messages, huddle calls/can set custom calls, huge set of stickers, etc
  • staying connected and updated with the team/org based in different time-zone/location
  • Drafts do not always remain saved when switching between messages.
  • it is hard to get back to a post if you are part of multiple channels
  • I wonder if there is something which notifies me after people reads my messages

  • Slack has a mobile version with push notifications.
  • The web-app version is particularly useful when you need your screen and are not at your home desktop.
  • The integrations speed up a lot of processes because you do not need to be constantly redirected.
  • Thread conversations can get lost unless you actively revisit your old threads. You would need a mention to receive all the alerts.
  • Copy and pasting images into a thread does not work with forward bot applications.
  • Bots created by other users can become annoying. You have to wait for the creator to change its functions.

  • Integrations. It integrates with almost every productivity tool I use.
  • Sharing files is super easy. You can simply drag and drop to upload files.
  • Searchable chat history is very important to us.
  • It is very easy to use. We were able to create "rooms" and group chats very easily.
  • I had difficulty setting up the right notifications. I wish that was easier to configure.
  • The stand-alone app works great, but sometimes I don't get notifications if I am using it through Firefox.
  • Call audio quality could be better but I don't really use it for that.

  • Ease of use! Slack takes very little to get up and running. The interface is very intuitive!
  • Collaboration is where Slack shines. It is so versatile in bringing all our teams, customers, contractors and vendors in one place, replacing email.
  • Integrations! Slack integrates very well with many products in your tech stack. There's no custom work required.
  • Missed threads are a common complaint from my team. When viewing messages in the unread or threads, it's easy to get distracted and lose that message. Some of us are subscribed to 100 channels and if you don't remember where a message was, it can be hard to find it again.
  • The search function is not the greatest. It takes some getting used to the filters and options to be able to really narrow down your search.

  • Slack does very well with notifications. You can create reminders for people or an entire channel.
  • Slack lets you add basic text formatting. For example, a tilde around a text will let you add a strike-through.
  • You can start a search from your message box. Type "/s" followed by what you want to find.
  • There's no Boolean search. Say you want to find all messages and use two terms, and you will get any messages that have either term.
  • No way to notify all messages from a particular person.
  • Away messages are basic. Teams are either active or away.

  • Create Groups for specific users and their roles within Slack.
  • Great for note taking.
  • The mobile app makes it easy to keep in touch on my laptop or while on the go with my phone.
  • A customizable notification center for messages would be a plus.
  • Drafts do not always seem to create/save when switching between messages.
  • Option for just “@mentions” would be nice (not including @here and/or @channel).

  • We can record the audio and presentation
  • We can share files as attachments and see within each message thread
  • It would be great if Slack can accommodate more than 2 people for free video meeting.
  • Need a button above the chat box which will lead to the bottom/most recent chat when we get a ton of messages or when we are at the top and want to see the most recent messages.
  • A WhatsApp feature which gives us an option to see who all have seen the sent messages in group/channel would be amazing

  • Slack is great for organizing conversations via channels.
  • Slack helps us stay connected to each other and our clients.
  • Slack has many integrations to enhance the overall experience and make transitioning between various apps seamless.
  • It would be nice if slack's HubSpot integration worked in private channels as well as public channels so our internal communications could be logged automatically in HubSpot (we currently have to copy/paste relevant info).

  • Slack speeds communicating up.
  • Slack enables transparent communications.
  • Slack has flexibility to customize notifications so you can balance noise with focus.
  • Slack enables you to keep important information top of mind (pin posts, set message reminders).
  • Slack enables you to schedule sending messages so you can respect colleagues' work hours.
  • If you have many channels, it can be hard to remember where you saw a post to get back to it.
  • If other users don't know how to manage communications specifically for Slack, then it can get cluttered and disorganized.
  • If a company uses both email and slack equally, it can duplicate effort and cause confusion where messages are sent – you need to create clear guidelines for your employees.
