Who Slack Is Best For
- SMBs: Slack helps centralize and organize team communication in one platform. You can reduce the use of other apps—such as email, phone, and video conferencing—as the platform allows you to perform all these with your teammates.
- Remote teams: Those that offer remote employment can use Slack to easily communicate updates, check-ins, and more. It also provides a searchable history that allows you to track messages.
- Freelancers: Freelancers can use Slack to update their clients on work progress and as a communication hub between other project collaborators. They can also join other Slack channels for networking purposes.
- Enterprises that have extra administration needs: While Slack is popular among SMBs, it offers a custom plan for those in larger industries to help communication within the company and still ensure security and compliance.
Slack’s pricing guide shows a free plan and three paid subscription tiers with monthly fees that range from $8 to over $15 per user. The main differences between the plans are the numbers of third-party app integrations, workspaces, and searchable messages, file storage size allocation, and access to advanced features such as screen sharing.
Up to 10,000 of most recent messages
*Annual plans are paid in full at the start of the billing cycle.
Slack’s free plan is ideal for small teams that want to try the platform for an unlimited period of time. You can access up to 10,000 of your team’s most recent messages, integrate with up to 10 apps (like Google Drive), have 1:1 voice and video calls with your teammates, and get standard customer support.
Recommended for SMBs, Standard gives you unlimited integrations and access to message history, allows voice calls, video conferences, and screen sharing for up to 15 participants, and provides custom user groups. You can also reach out to customer support 24 hours, seven days a week.
This tier is best for larger businesses or those with additional administration needs. Apart from all the features included in Standard, you are provided advanced identity management, granted compliance requirements, and guaranteed 99.99% uptime and 24/7 support with four-hour response time.
If you are part of extra-large businesses and those in regulated industries, then this plan is for you. Your team gets all the functionalities in Plus and access to large scale collaboration and alignment with support for up to 500,000 users. You are also given customized support with a designated account and customer success team.

Most Helpful Slack Reviews
Most Slack reviews I have read online are positive, with many highlighting that it has helped streamline communication within teams and organizations. Many users love that they can group communication into channels so that they can discuss casual and fun topics along with more formal team updates. Unfortunately, that can also be a downside as most of the negative reviews I read noted that messages and notifications can get overwhelming.
Great for team communication and updates
“Slack is great for more informal communication, which helps clear up your inbox from unnecessary emails. You can organize conversational topics with channels, and the use of emojis and polls works great too. It makes for a fun way to communicate in work and creates a positive atmosphere!”
Default notifications can get overwhelming
“I believe the default to get notifications from a new channel needs to be changed. After so many channels are made, the notifications can get overwhelming. A possible solution is to group multiple notifications into one notification. Example: ‘There are 10 unread messages in the #general channel’ instead of sending 10 notifications.”
Slack Frequently Asked Questions (FAQs)
Can I assign different permissions to other users?
Yes, you can. Slack allows you to assign different permissions based on two kinds of roles: administrative and non-administrative. Administrative owners can be Workspace Primary Owner, Workspace Owners, and Workspace Admins; while non-administrative roles include Members, Guests, and Invited Members.
What channels can I create?
All Slack workspaces have a #general channel that includes all members. You can create other channels for different purposes and groups such as departments, locations, and announcements. Slack recommends using sets of standard prefixes to indicate what each channel is for.
Can I customize my notification settings?
Yes, you can. You can choose to receive notifications for all new messages or restrict them to direct messages and mentions. You can also set up keyword notifications, which alert you whenever those keywords are mentioned on any channel that you are a part of.
