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 …
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 …

If you population likes technology, then I would recommend Slack. It is more difficult to implement if not everyone is on Slack or knows how to use it. Slack was used well by some employees who loved it. Slack allowed them to plan annual events and get feedback and ideas from those involved in the event
Zimbra is great for an email system for a medium or large organization with appropriate IT staffing. The system is easy to use for end-users, and has a fantastic web interface. Unfortunately, it is overly complex, when considering staffing requirements and price, when compared with Office 365 or Google Apps for smaller organizations. For other education customers, it is hard to compete with Microsoft and Google providing their services for "Free" now though
Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule
Zimbra's mobile application leaves much to be desired; it is its weakest point.
This forces the use of third-party applications on smartphones, which only offer a more or less complete integration with the ActiveSync protocol.
Zimbra allows for an on-premise scenario, which is not for everyone, especially considering that the trend nowadays is to outsource email; in any case, it also offers this alternative.
The cost of Zimbra as a SaaS solution comes too close to that of more widely adopted competing options.
Zimbra lacks a robust integrated chat system, which its competitors offer.
To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.
Slack is one of the easiest platforms to use! It is very aesthetically pleasing and you can arrange the chats and other features the way you personally like it. They kept it pretty simple for people who aren’t looking to do anything more than streamlining communication, but they definitely have options for folks to build out the Workspace more.
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.
Yes, the app works 24/7. I don't even recall having any period that we could not use since the implementation. Even the maintenance periods are barely noticeable and our work is not impacted by it when it happens.
Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.
Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.
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.
Having had a lot of experience with Google Chat and Teams, Slack is far and away the better option. In comparison to Teams, Slack is much cleaner with a far more user friendly AI, Teams is far too clunky and feels tiresome to use, whereas it is super easy to pick up Slack and be able to configure it do exactly what you need. Whilst I don't find a massive difference between the usability and UI of Google Chat to Slack. Slack's range of features far outweighs Google Chat. The ease of external connections, workflows, file sharing, external connections for notifications (Make, Zapier etc), plus the huge range of apps you can connect to enhance your workspace is incredible. Google Chat does benefit from directly integrating into your Google Suite so you can get access to automatic status updates based on calendar activity, which would be nice for Slack to have
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 and notes, all in one platform. It is constantly updated and the operation of its connection in mobile equipment is remarkable and very efficient. Additionally, it is able to easily integrate with Outlook solutions with its connector, which brings all the benefits of Zimbra to the user under the interface known as "mail manager." So far, I have been using Zimbra for several years and I have not missed my previous work platforms.
Zimbra is a cheaper email service than other similar platforms and in my point of view offers better features, that's why the company migrated services to this platform several years ago and without a doubt, it has been the best investment.
Zimbra has a more user-friendly interface for employees, this has improved response times to external customers of the company.
The implementation of Zimbra in the company motivated the IT engineering department to make improvements in open source to adapt it to the needs of the company.
