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 …

Salesforce
Slack is great for tracking commits to new coding projects. You can take parts of code that still need to be implemented later and easily search through the history of comments if there is something that goes wrong with a code commitment. It can be difficult for people that only like Teams to adjust to a new platform if you are using both to communicate.

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

Cons
Salesforce
  • 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.
  • It lacks AI integration.

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.

Usability
Salesforce
My rating was 7. Its intuitive interface and user-friendly features like channels, threads, and integrations make it excellent for team communication and onboarding. However, its usability is held back by the resource-intensive desktop app and cluttered feeling in large workspaces. The mobile app's performance and unreliable notifications have also been noted as weaknesses.

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.

Reliability and Availability

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.

Performance

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.

I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.
One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.

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.
