Chose Zimbra Email & Collaboration
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 …

I would definitely recommend Slack to everyone who needs a messaging platform for work. The thing that I most appreciate on Slack is the possibility of talking to my coworkers without using my personal number or personal apps. This way, I can separate what is work and what is not. Slack even has the option to mute notifications after work hours. I'm able to keep track of every project and discuss them in an easy and fast way. Another great thing is that you can keep and check the history of channels and groups, this way the discussions are never lost when someone joins the project in the middle of it or someone leaves, the history is always there. The only thing that bothers me in the platform is the system of threads, where you can easily lose the messages cause they look kind of hidden. If you have multiple subjects with someone and the person only responds in threads, it's very common to lose their messages.

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
  • While threads exist to keep conversations organized, managing and finding threads within channels can be cumbersome. Enhancements in thread management and search capabilities could be beneficial.
  • Slack has a limit on the size of files that can be directly uploaded. Increasing this limit or providing smoother integration with external file-sharing services could be beneficial.
  • Managing guest access can be cumbersome, and simplifying the process for inviting and controlling guest users would be beneficial.
  • Slack primarily operates within individual workspaces, making it challenging to collaborate across different workspaces. Enhancing features for inter-workspace communication could improve collaboration for organizations with multiple Slack instances.

  • The password change is not activated when you access by IMAP, Pop3 or Exchange sync. You have to know that the password change is required and you must go to the website to do so.
  • The management of mail rules should have more checking options.
  • There should be more applications compatible with Zimbra, the ones that appear in the Zimlets.

As useful as Slack has become within our company, I feel fairly confident we will continue to use Slack as a communication tool. They continue to improve their software and add value to its use within our office. Customer service delivers, which is an absolute must. Looking forward to how they improve.

Usability
Salesforce
As long as you use the basic chat features and nothing more, it really is super easy to understand and use. Once you want to take advantage of some of the more advanced features and capabilities, that's when things get complicated. Anyone who has use SMS or a chat program before will be able to figure out the basics though, so rolling this out should be relatively straightforward and not required exhaustive training. Teaching chat etiquette is something else though.

I've never had to contact support for Slack which is a great testament to its ease and use. Adding people outside of the organization takes a little getting used to, but ultimately allows for greater collaboration between FTE and contractors. There is no clear alternative to this software, so it's the best we can do for now.

It always helps if you communicate to everyone in the organization how important it is to drop whatever other chat tools they are using and jump quickly to Slack. They will all fall in love with it.

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.

Microsoft Teams got very confusing for me with all of the tabs and different things to learn how to use it. I felt that Slack has a much cleaner look and makes it easy for anyone to learn how to use. I also like how it integrates seamlessly into our Google/mac workspace!

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.

Return on Investment

  • Allowing our team to communicate, especially in a remote-first environment is invaluable
  • Sharing sensitive information securely is a great feature so we don't have to rely on other software
  • Direct communication with our clients through Slack Connect helps us reach a larger audience and therefore increases our opportunity for revenue

  • Since all of our ROI studies and strategies are performed at the corporate level, I'm really not sure what positive or negative impacts Zimbra has had on our overall business objectives. I can say that at least one positive impact it has on my business objectives, in the medical record department, is the ability to be as paperless as possible.
