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

"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."
"It is fast, and it increases your productivity."
"Zimbra Collaboration has a good web interface."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The most valuable feature is sending messages as well as text and documents. It's a big solution for us since internal communication is a must in our organization."
"The most valuable feature of Zimbra Collaboration is email functionality."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"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."
"The backup and storage management features of Zimbra Collaboration are valuable."
 

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."
"The solution could improve by making it easier to use."
"The installation is not straightforward, it can take two days for the full implementation."
"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."
"It would be great if a group chat feature were created to allow for a team environment."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"We have had an issue with security."
"The tool should improve its multi-cloud feature."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
 

Pricing and Cost Advice

"It is fairly expensive. They have monthly and yearly licensing options."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
"Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate."
"We pay yearly licenses for Zimbra Collaboration."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
