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 think Slack works really well in office settings, or even for any group of people who need an easy way to communicate with each other through organized channels. It may not be the best for those who intend to use it as a social media type app, it is more geared towards business use.

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

Pros
Salesforce
  • Automated Notifications: Integrated tools like Jira, Trello, and Google Drive to receive automated notifications and updates directly in Slack, improving visibility and efficiency within the team
  • Message Encryption: Slack encrypts the messages in transit and at rest, ensuring the security and privacy of sensitive information and making our IT team's life much easier.
  • Reminder Bots: We used Slackbot to set reminders, automate follow-up actions, and provided information based on user queries.
  • SurveyMonkey Integration: Integrated our Slack with SurveyMonkey to distribute surveys and collect feedback from team members, streamlining the feedback-gathering process which was a huge support to our HR and Admin team.

Cons
Salesforce
  • The only thing I can think of is that it is easy to create too many channels. This has more to do with the team using Slack and less to do with Slack itself. maybe some direction on Slack's part on how best to utilize channels would be helpful.

  • 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.

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.
