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.

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.

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."
"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"
"The price of the solution is low."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"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."
"The solution is competitively priced."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
