Siddharth Mallya - PeerSpot reviewer
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.
Muhammad Talha Baig - PeerSpot reviewer
One of the premium features was customized rooms tailored to the collaboration needs
Zimbra's strength lies in its individuality, and it should focus on leveraging its unique features rather than trying to emulate competitors. My organization has certified Zimbra technicians, so we believe we can utilize Zimbra certification. However, I was recently informed by Zimbra that no such certification exists. I have recently completed the test kit, and after the training, I will gain access to tickets. Therefore, if any clients are experiencing issues, we have a certified technical team available to provide support 24/7. This is how we can cater to our client's needs. I recommend Zimbra to small-scale and enterprise customers. Anyone, even those with 5 users, can opt for Zimbra. Overall, I rate the solution a nine out of ten.

Quotes from Members

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

Pros

"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. This solution segregates your email according to your preferences and how you want to categorize emails."
"Good email solution and it's open-source."
"The product is easy to set up."
"Zimbra Collaboration has a good web interface."
"Zimbra Collaboration's sharing features are most valuable."
"The configuration is simple."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"Network NG Modules are valuable to us."
 

Cons

"It can have a few more integrations. As far as I know, it is being integrated with Salesforce."
"Superhuman could be improved by being made available across a broader range of devices including Android and Windows PCs."
"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."
"Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server. They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure."
"We have had an issue with security."
"The antispam and antivirus features are hard to understand on mobile devices."
"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."
"I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many."
"I would like to see a Microsoft schedule function added."
"Zimbra Collaboration does not have a solution roadmap as aggressive as the new collaboration mail solutions. Additionally, they can have a better interface and integration with single sign-on."
 

Pricing and Cost Advice

"It is fairly expensive. They have monthly and yearly licensing options."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"When it comes to the licensing of Zimbra Collaboration, my license covers the servers and I find its terms to be much simpler than those of Microsoft Exchange."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"Zimbra Collaboration offers a good price-to-feature ratio."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
