Email triage solution that actions and handles emails based on preferences
Superhuman could be improved by being made available across a broader range of devices including Android and Windows PCs. Superhuman is also a phone app, which is available only on DiOS right now. Because it's not available on Android, you have to use Gmail for your phone, and use Superhuman for your desktop. The search feature could be improved. Currently, Gmail search is a lot more robust because you can filter results based on your requirements. Superhuman does not offer this way of searching which can make emails difficult to find.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is a productivity-driven email software that is fast, increases your productivity, and cuts down the time you spend compared to traditional email software."
"It is fast, and it increases your productivity."
"The best feature about Superhuman is the fact that you don't have to manually go through your emails, as this solution segregates your email according to your preferences and how you want to categorize emails."
"It is the best open source collaboration suite that I know, because it provides high availability and more performance than the other solutions."
"The Zimbra Collaboration's most valuable feature is web access."
"The web interface is powerful and easy to use."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"This is a good email solution and it's open-source which is great and the most important feature for us."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The solution is easy to implement."
"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."
 

Cons

"Superhuman could be improved by being made available across a broader range of devices including Android and Windows PCs."
"It can have a few more integrations. As far as I know, it is being integrated with Salesforce."
"Zimbra is not very stable, but it's okay."
"Zimbra Collaboration's video conferencing could be improved."
"There can be difficulties resolving problems on the server side when problems arise."
"It does have a few bugs. However, they are small and can be worked around."
"Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."
"Zimbra Collaboration could improve the migration from a basic solution to a more containerized solution. For example, the installation should be able to extend to the containers and manage them with some solution, such as OpenShift or Kubernetes."
"There are some security issues."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
