Slack vs. Zimbra Email & Collaboration

For a company that works with remote employees, like our company, Slack is extremely good at allowing instant communication, files sharing, calls, huddles and many other features that makes it so easy to feel like that communication flows quickly and easy. It is also a great ally to manage projects as it allows to integrate with tools like monday.com, helping you to streamline communication with the team overall.

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

• I love using the remind function to have slack tell me about things that I need to remember. It can be used for exact dates and times in the future and even recurring reminders. It's definitely one of my favorite features.
• Slack allows you to "huddle" with other teammates. This is a quick voice call and is way better than trying to call someone on the phone.
• Slack's ability to integrate with many other software makes it invaluable. We can have other software send us notifications or reminders in Slack that we wouldn't have received otherwise.

• Filter emails with specific information required.
• Very good storage capacity.
• Has a mobile version and another web.
• It has a friendly and modern graphic interface.
• It is compatible with all operating systems.

• The notification within the web app has to be better in terms of missed notifications, while not looking at screen, maybe have a reminder notification every 15 minutes
• The messages have to arrange themselves according to the urgency or some importance level need to be introduced for the messages

• 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.

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.

Slack is the superior offering for what we do and who we communicate with. The other programs offer basic features, but Slack continues to innovate and is business-first, which is very helpful for our small team. The feature set and integrations are better in Slack than other offerings we have evaluated

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.

• We have a story when one guy mentioned in a our site group with tag @here about his wedding, he didnt know that @here works only for people who are online, so most of the people missed the message, slack is not the best place to update about the important things
• Slack helps to solve and be updated if you have an internal problems and you want to know how the solving goes

• 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.
