Considered Both Products
Mattermost
Chose Mattermost
They're very similar. I think it's really a matter of preference. Again, one of the things I like about Mattermost is that it's strictly for business (atleast for us) it's different from the more mainstream messaging apps used so we can kind of separate work vs personal messages.
Chose Mattermost
Slack, Microsoft Teams and Discord
Chose Mattermost
It's cheaper and similar to Slack.
You can break down your project modules better here.
It's secure and self-hosted.
Chose Mattermost
Much more expensive than most chat applications but you have more control over things by self-hosting. Your security team will be able to design a very secure place to store all your code, passwords, and internal details, but most companies will not require this. It would be …
Chose Mattermost
In comparison to Slack, where Slack is strictly for internal communication, Mattermost actually has the format to display and not alter source code. Google chat is also even more limited in comparison to Slack and Mattermost. If you collaborate on code every single day, then …
Chose Mattermost
It is just as good if not better. Can be a superior option depending on the needs of your organization.
Chose Mattermost
These products all required cloud connectivity and licensing that was a significant cost. Mattermost allowed us to pilot this among just the Ops team and then evangelize this to the other infrastructure team. This allowed us to slowly show the value of this software and expand …
Chose Mattermost
Unlike Slack and Discord, Mattermost is self-hosted and focused on security. I used Discord before for community management and much simpler and less secure operations. Slack is great, but the fact that is cloud based takes out a lot of its independence.
Chose Mattermost
We used to have Mattermost and now we have Microsoft Teams. They are both very similar. Mattermost and Microsoft Teams are both great for communicating internally via calls, chats, meetings, etc. They are also both easy to set up an use. However, the Microsoft Teams mobile app …
Chose Mattermost
to reduce cost we shifted to Mattermost.
Chose Mattermost
Mattermost works better in that there aren’t constant updates and changes which can make finding past messages difficult. Mattermost also works better for channel creation and communication
Chose Mattermost
Slack is by far my personal favorite due to the age of the platform and the maturity of the features. Mattermost is a close 2nd-
Chose Mattermost
Honestly iv just used these two but when it comes to customization, they don't come close to Mattermost. Slack and Teams are Less flexible, Not self hosted. Not Open source,etc I will also say that i noticed integration capabilities are very limited with teams and slack and not …
Chose Mattermost
Mattermost is much faster and easier to use. It also has many more features beyond chat. They are more customizations and features for workflow and messaging on this platform also. The ability to integrate with other platforms via plugins, the security features, and the open …
Chose Mattermost
Mattermost is easier to use, faster, and less resource-intensive. Cross-platform support is great, and the mobile experience is awesome.
Chose Mattermost
I feel slack is a bit more difficult to use overall than Mattermost. Mattermost makes the tasks of communicating across departments and team members easier, as well as giving the ability to share information via hyper links, attachments, and other forms of communication among …
Chose Mattermost
We selected mattermost since we can control storage of our data. Slack is a great tool and offers more robust features compared to mattermost. However, the previously mentioned reason & the competitive pricing allowed us to stick with mattermost.
Chose Mattermost
key selling points for us was that its open source and can be self hosted.
Chose Mattermost
Mattermost is cheaper and offers the possibility of self-hosting compared to other competitors. This is a great advantage for our company.
Chose Mattermost
Microsoft Teams feels quite clunky and the video chat is buggy. Slack is close but maybe not quite as feature-rich. Mattermost just feels like the right tool for a company my size ~1000+ users. No one has had any major issues with this tool and there haven't been any …
Chose Mattermost
First of all, we don't lose messages; we can see or search messages from any point in the past. Second, it offers to manage the whole product ourselves from hosting to serving users of our organisation. We feel that we have full control over data, managing users, …
Zimbra
Chose Zimbra
We used Zimbra Email & Collaboration in two scenarios: first, on-premise with the open-source version to save costs, especially since solutions like Office 365 or Google Workspace were not as mature or widespread at the time. Later, we benefited from cost advantages with Zimbra …
Chose Zimbra
There are a lot of features that Zimbra Email & Collaboration has that gmail and m365 have. You can chat within your team members with Zimbra Email & Collaboration. The issue that we have not been able to figure out though is mobility of Zimbra Email & Collaboration. You can …
Chose Zimbra
We chose Zimbra because Zoho Mail is too pricey with less-functionality than Zimbra. Zoho's UI is better, but we need more than just UI, we need many features that Zimbra has. G Suite is the best for team collaboration of course, but because of the price and our needs we …
Chose Zimbra
Zimbra is undeniably a complete package and offers many practical tools, in addition to the knowledge that the company has. It is a great acquisition for a company that will soon see a significant change in terms of organization, deadlines, efficiency, and more. It has an …
Chose Zimbra
Zimbra is a more specialized software designed for our company and its needs. The software was customized to represent our colors and project our brand, what other companies do not have. With Zimbra, we have a private network of only employees which allows us to confidentiality …
Chose Zimbra
Zimbra is a significantly cheaper option than one of the Microsoft solutions, such as Exchange. It is able to run in a free environment, as it is in the case of Linux. It offers the advantages of a powerful mail manager, such as indexed searches and the integration of contacts …
Chose Zimbra
We selected Zimbra because it has a lower cost in the market, offers more development features for its open source, has a very easy to use interface and adjusts to the needs of the company.
Chose Zimbra
Zimbra provides a robust and reliable software that delivers what is promised. We have tested Zimbra in a pilot project before deploying it in production. Incidents and crashes are rare and you have tools to recover it if necessary. Initially we had a contract with support to …
Chose Zimbra
  • We were originally a Groupwise shop before changing to Zimbra in 2008. Zimbra, from an end-user standpoint, pricing, system administration, and management is a far better system.
  • We use Google Apps for our students. We did not find it to be suitable for faculty and staff due to …

Likelihood to Recommend
Mattermost is definitely appropriate for a growing company with team members spread out across the u.s. and Canada. It’s given me the ability to have access to anyone with the information I need or the ability to develop friendships, working relationships with people I otherwise wouldn’t have access to

I consider Zimbra Email & Collaboration a viable alternative to the major American cloud email platforms. In a scenario where data protection and privacy are critical, especially in an on-premise environment, Zimbra is a very suitable solution. It is also capable of offering a comprehensive set of tools and additional features (tasks, calendars, contacts, briefcase) in an integrated manner.

Pros
  • Easy intergration to our main CRM (Monday.com)
  • I'm not techy myself but I have seen a lot of our previous integrations in Slack transferred over to Mattermost so that's fun
  • The desktop and phone app (android) works well enough. I haven't tried it on the Apple ecosystem yet.

  • The management of incremental mail backup. It is very simple, and the administrators of my company recover information quickly.
  • The management of the distribution lists is structured. This allows easy distribution of mass information.
  • The web application is very complete and intuitive.

Cons
  • Basic features like custom status, collapsed reply threads are JUST rolling out - kind of slow for a workplace chat app.
  • I don't really get the idea of Playbooks and Boards - there are better, dedicated tools for stuff like this and it's not so easy to turn off.

  • User web interface could be more friendly, but it is enough for daily use. It could be renewed and has to consider some usability concerns. Improving usability would significantly improve users' satisfaction.
  • Message backup recovery is not a simple activity.
  • As an administrator, some of the features work better using the command-line interface.
  • The webclient uses ajax requests in almost every event. Because of that you may need a fast internet connection to have a good experience. You can switch to HTML version but it will limit what you can do.

Mattermost works perfectly within our company as a way to communicate seamlessly. I have had no issues with the product and continue to use it often while on and off site. The mobile app allows me to continue to communicate with my team even when I don't have my laptop with me.

Usability
It's an extremely easy to use software, and I would recommend it to every company that is growing. I think they could improve their notification system, as it gets a little spammy sometimes and important notifications get lost. Also needs to improve the number of private chats that you are allowed to create.

The web usability of the solution is adequate, with all functions integrated into a single interface. However, it is important to note that in the desktop environment, it lacks its own application and relies on ActiveSync synchronization with reference solutions like Outlook or Thunderbird. Some features, such as the briefcase, will be excluded. The same happens on smartphones.It is also common for competing solutions to include integrated chat or video call tools, which Zimbra lacks. These shortcomings are among the most frequently requested by users.

Support Rating
We have not had to contact support for Mattermost ever. All that we have needed has been available in the documentation or website. One of our DevOps team members set it up in a couple of hours. The whole team was using Mattermost that same day. No support needed.

This went as expected. No surprises or major hurdles.

Overall, we were satisfied with the implementation. We perhaps should have spent more time consulting with Zimbra or others regarding best practices but as we got to know the system better we were able to make changes relatively easily after the fact.

  • We were originally a Groupwise shop before changing to Zimbra in 2008. Zimbra, from an end-user standpoint, pricing, system administration, and management is a far better system.
  • We use Google Apps for our students. We did not find it to be suitable for faculty and staff due to its lack of shared accounts.
  • We are moving from Zimbra to Office 365. Office 365 offers just about all that Zimbra had, though its web interface is inferior to that of Zimbra. It does offer us greatly reduced costs though, and high availability. If Zimbra were to have a fully HA environment, we may have stayed with them.

Return on Investment
  • The platform is adaptive to storage data center outages in case our cloud storage provider goes away, Mattermost still works with our local database. However, files couldn't be shared. We can switch storage to local temporarily; that's a benefit. Later it all syncs up to main storage.
  • When our team switched to Mattermost from paid solutions, we had much savings and access to unlimited past messages and storage quota (we use our cloud storage provider)
  • We have better visibility of our tools and other products running adjacent to Mattermost due to integration capability. We use it for notifications/ updates sent from other products.
Read full review
  • Improved internal communication and dissemination and distribution of messages and corporate objectives.
  • The creation of an internal network of employees is something that gives us security and confidence.
  • Having a private and exclusive messaging system differentiates us from the competition and from other companies.
