Accounts Payable

The best features of Slack are its innovative interface and easy to use features. Slack makes it simple, and even kind of fun, to communicate with your coworkers quickly.

Student

While they are only visible to me, I am always worried that I accidentally posted something wrong.

Technical account manager

I like the different slack channels for various departments, tech-support, team, individual messaging, and celebrating my teams successes or helping each other out with account  challenges.

Manager of Data Integration

Slack has been a winner for me no matter which role I am filling. Teams adopt it quickly it's easy to use, easy to set up, and has abundant opportunities for integrations.

Executive Assistant

I disliked the inability to make a public group "private" after it's creation. Would occasionally lag and my.

Director

Slack has been the best decision made as far as intra-company communications platform, and also project friendly. Sharing of files and easy display help save time and effort.

Senior Software Engineer

Super easy set up, effortless onboarding, and great pricing plan for small groups. It has strong search functionality and intuitive threading.

Customer Success Manager

I hate hate hate how often I struggle with using the video share and audio when someone calls me on slack. It almost never works for me.

Entrepreneur

I like the chat option because I can send and receive real-time messages and chat with my team directly and the Slack messaging app is very powerful and amazing.

Logistics / dispatcher

You can have fun and customize. For example: We have a 'Jokes' channel that the slack bot will tell you jokes if you ask 'bot tell me a dad joke'- It's amazing.

It's super easy to stay connected with all of your colleagues. The desktop app is very nice.

It combines the depth you get from email communications with the efficiency of texting. And, if you do it right it is great for building a good, fun company culture.

Admissions Intern

In addition, files are saved and archived for easy access. I also liked the ease of use and ability to collaborate with anyone in your organization.

Research Analyst

They found it awkward that everything was a chat in Slack and uncomfortable with sending out a message that may "bother" others for small issues, and reverted to email, even with consistent reminders.

Head of Marketing 

I love the giphy option, some of the gif’s are hilarious. Also, some of the integrations are very useful - google calendar especially.

SVP Operations

I like the ability to quickly reach out to someone with a quick question vs. email. Having groups is also useful for the same reason of quickly updating a broader, interested audience.

Associate

Slack was a great platform that made the workplace feel like a community. Its user friendly interface allowed everyone to come together and share messages of high importance.

Customer Insights Specialist

OVerall Slack is very good and highly recommended if your budget allows it.

The incoming hook limitation of maximum content length is the hell (Mattermost don't inform the customer about a message which was higher above the hard coded message size limit).

Marketing Manager

What I like the most about this collaboration software is the simple and logical UI, which is not overloaded with lots of unnecessary features. It has all we need for successful communication.

Cross-platform applications ready to use. Amazing open source community built around the product, friendly and helpful people.

CEO / Lead Architect

The software is easy to use, similar to the commercial app Slack. It provides good thread tracking and the interface is clean and easy to understand.

Scrum Master 

I like how easy is to use and allows different "rooms" for collaboration for teams. It is a great tool for fast daily communication.

IT Security Engineer

Can be hosted on-premise. Good community support - Apps and Integrations brings great support to exchange data with external systems for software development teams.

Chief Growth Officer

Mattermost is intuitive to use and easy to implement in your company. It has a good amount of integrations.

Technical Writer & Digital Marketing Specialist

Honestly, the most use we get out of this product is having fun with the wide range of emojis you can add to posts as reactions.

For its purpose, I have found nothing about the software that I can find to complain about.

Senior Developer

Running the software locally means you can keep a much better eye on its security and usage. Its user management and directory integration is superior to Slack's.

A bad user interface, a lot of bugs, sometime you need to restart it in order to make sure that everything works as expected.

Graphic Designer

That's a nice alternative to Slack. Managing channels and using the entire product is very easy and intuitive.

Head Of Design

It allows all our staff to quickly chat about things without clogging up inboxes or having them on their phones. Groups and channels are great, especially for management needs.

Software developer

Great for communication and to stay connected.
