Mattermost boost productivity by unifying teams in my organization in one single workspace through corporate communication channels.
Video conferencing isn’t robust enough that’s why it demands to be integrated with external web conferencing systems like Zoom Meetings.

Project management and business instant messaging.
Mattermost combines messaging and project management capabilities in one place.It has a robust backend integration feature, which boost it’s capabilities.Project coordination is another great thing about this tool.
I do not like that Mattermost demands to be integrated with external web conferencing apps to boost video conferencing.

Screen sharing enhances large file sharing via drag and drop.Business instant messaging.
I like how Mattermost has a lot of features:- internal communication, screen sharing, web conferencing, business instant messaging and chat all in one place.
For nearly a decade now Mattermost has been a useful program, with no drawbacks in business matters.

Perfect low-priced alternative to another internal messaging tools. Provides less functionality but everything that you need in smaller companies.
We switched to this product because of lower price and option to have self-hosted messenger. Allows you to create secured and perfect internal communication and collaboration tool. Video calling and file sharing is also implemented. You can prioritize chats making them favorite. App runs smoothly.
Sometimes we have problems with video calling tool. Also sharing images in some formats make us some troubles.

Setup was smooth, server operation is transparent, user management trivial and everything just clicked into place when we were looking for a simple yet functional solution to team chat
Mattermost was absolutely trivial to set up and maintain, which was a huge plus back during the first dawn of Covid where we struggled to find a solution to team chat that allowed us to host on-premise, keeping all our data local - a must for many projects which have complicated data privacy regulations that are a nightmare to work around with cloud based products
One of the paid feature is unlimited search, and as a free user (10,000 line search limit, I think), it is often unclear whether you can't find what you're looking for because you hit the limit or because it's just not there.

It is easy to deploy among a large scale corporation, as my company has been using it for over 1 year. Previously we used Hipchat, which did not have as many features or functionality. I honestly cannot say enough about Mattermost
Texting like platform creates a wonderful way to ping someone of your activities, needs, or simply to communicate. Excellent way to notify a coworker quite quickly without needing to move and converse. I love the ability to switch on and off the auditory aspect of the application. The group option is cool as well. With large companies, you can jump in and out of groups, such as "support" groups or "tech" groups to quickly answer pressing needs, and then jump back out.
Simple integration into business- you just need a computer or smartphone/tablet to really utilize this software. There isn't anything I don't like about this product, very well used and liked by the whole company.

We started to use Mattermost on quarantine, a very secure and convenient tool, especially in new WFH reality.
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. Also, it's very easy to deploy and integrate. Ensures really secure collaboration.
Great tool overall, perfectly performs its functions, didn't face any issues or drawbacks. Highly recommend.

I don't know about the overall cost, but I assume it costs less than Slack. Given that, it's not a bad alternative. I think it's main issues aren't so much limitations in functionality as just having a less user-friendly UI overall.
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
There's something slightly less intuitive about the UI than similar competitors (i.e., Slack). Sometimes the search function in particular is confusing and could definitely be improved.

I really liked the platform. My team found it easy to learn how to use it. Now we are replacing email communications with Mattermost.
It's free, it's open source, it has very easy to follow documentation. It's safe and secure. It works smooth.
It could have sub-channels and addittional options to configure. Could give native option for audio sending.

Mattermost allows the team to communicate and maintain control of our data. It does take some time to setup and maintain, but it is worth it for attractive UI and options it gives you.
The cost. The fact it is free is what got my attention. After that I found out I could self-host it, which made it even more useful. I can use Mattermost for my team(s) and still control my data. The interface is attractive. You can use a Mattermost app or you can use the web interface.
The install and maintenance is on me. You need to have enough time for the install and maintaining the server for the system. If you don't have the time, this is probably not the best option for you.

despite it being little more harder to use, it's more enjoyable sometimes all you need after hard day at work is funny co worker sending some hilarious gif.
the main think i like in Mattermost is design it feels lighter, it makes me feel happy, emojis are great way to impress and make communication more informal, also ability to use gifs is one of most useful features
compared to other communicators i used it feels little bit harder to use, its easy nothing very difficult but it feels like i need some extra effort to find person and use direct messaging.

Mattermost is fantastic for internal messaging for an office looking to communicate between departments discreetly. The web app is flawless, and the mobile app is useful with some glitches, i.e. force quitting, delayed responses. I would highly recommend Mattermost for those looking for an intuitive instant messaging software suited for professional use.
Mattermost is customizable and fairly simple to use. There’s essentially no learning curve as it has all the familiar landmarks of instant messaging. I love the ability to create customer emojis which my office lovingly partakes in. It allows us to work efficiently and quietly, while being able to communicate seamlessly between departments. The interface looks clean, and I can’t think of any glitches to date on the web application version.
I would like a better search feature, and perhaps the ability to search by person rather than just chronological. I use both the web app and the mobile app, and the mobile app can occasionally force quit and delays messages now and then.

Between communications platforms, voice calls, emails, and texting, there are numerous ways to communicate with colleagues. My company decided to use Mattermost because it helps us avoid clogging up email when we have quick questions to ask or non-essential company-wide messages to send.
My company has over 200 employees ranging multiple departments (from editorial to strategy to support) and offices. Mattermost helps us stay connected in a quick and efficient way because we can easily connect and disconnect from channels according to our business or personal needs. For example, I am part of a group that connects members of my immediate editorial team and other groups that connect my larger team, my support resources, and strategy team members. It helps me stay organized in my communications, and it's much easier than using email or texting to communicate quickly with people on a daily basis.
Because my company is relatively large, we have dozens of channels on Mattermost. I sometimes find it difficult to find specific channels that I'm not already a part of, especially if I don't know the precise name of the channel or group. This sometimes ends up being a hindrance to what is typically quick and efficient communication. Nevertheless, I enjoy using Mattermost and would recommend it to other businesses.

Mattermost got everyone on our team working together more. Made it way easier to track how a project is going and made it super easy to share files.
We use mattermost in our office, we work in a highly regulated industry and needed something that could offer more security while making sure we keep our files transferred among one another in our control.
Very minimal not too like. They are growing their emoji collection, but would like to see some more fun stuff in the program to insert some fun into the mundane work day.

One place for team communications that Slack/Hipchat users find familiar and everybody else learns easily. Integration with other software in our mostly open source workflow.
Great integration with as many systems as we want including with SSO and being able to roll our own tweaks when necessary.
Audio and video integrations are still in beta and a bit rough. My teams pretty much prefer out of band calls for that which detracts from team interactions. Also notifications are a little dicey.

The interface is pretty much self-explanatory. This is why the user acceptance is quite good. Customizing the interface is straight forward and can be done at user level. The open source cummunity around Mattermost is really nice and welcoming. Apps for every operating systems are available and easy to use once manually set up. Scalability was never a problem with 1000+ users.
Setting up integrations is more complex than with Slack, where integrations can be installed with one click in the backend. There is an app directory, but the apps need to be set up manually. Once set up, they just work. Incoming webhooks are the only exception; they work out of the box. Mobile perfomance is gradually getting better, but it's not yet up to Slack's par. The Windows-app is not yet ready for big scale rollouts via group policies.

Control over our hosting and data
Open source and self hosted, I don't get irritated if slack goes down and I don't have to worry about my data security or my data just being lost of the company goes belly up. This is far and away our primary reason for using this instead of Slack,Hipchat,Cisco, etc. It doesn't ask anywhere on this survey, but we use it for about 80 people, 60 staff and then various clients and contractors. We don't use many of the enterprise features, we just pay the licensing to support open source.
iOS and Android Apps are pretty idiocy, they're getting a bit better, but they are easily the worst part and I field lots of complaints about them. I would trade all new features and other fixes for faster and more reliable apps. The web interface is much better, but a bit buggy, nothing serious but little lags and quirks persist longer than I would expect. The install process is also a bit silly, copy pasting files and such, a provided .deb or a custom apt repository would be 100x better and save me upgrade time and downtime. The lack of this is surprising considering almost all other software I use has this, even when it is free or small.

Like I just said, full and easy auditing of the stack. The API is clean enough to pair with pretty much anything.
Can be installed on-premise and is open-source. I can secure and audit the software myself and I don't have to trust any external partners.
Right now I would say : backups. I have not found a good canonical documentation source about backups (and most importantly, how to restore them). It's nice to see Gitlab backing of the project, but I hate the fact that it's bundled together.
