Executive SummaryUpdated on May 21, 2025

Zimbra Collaboration and Amazon WorkMail compete in enterprise email and collaboration solutions. Zimbra Collaboration excels in pricing and support, while Amazon WorkMail is favored for its features, making its higher pricing justified for many.

Features: Zimbra Collaboration provides email, chat, calendar integration, and open-source flexibility for customization. Amazon WorkMail offers seamless AWS integration, robust security, and compliance features. The security and cloud integration of Amazon WorkMail are notable advantages over Zimbra Collaboration's customizable environment.

Room for Improvement: Zimbra Collaboration could enhance its integration with third-party apps, improve user interface design, and strengthen security features. Amazon WorkMail may benefit from greater customization options, enhanced offline capabilities, and improved user training materials.

Ease of Deployment and Customer Service: Zimbra Collaboration offers flexible deployment for varied IT environments with strong customer support. Amazon WorkMail excels with AWS infrastructure, simplifying integration and scalability while providing extensive documentation. Leveraging AWS's support ecosystem, Amazon WorkMail has a deployment advantage, but Zimbra's flexibility suits specific configurations.

Pricing and ROI: Zimbra Collaboration, with its lower initial setup cost, presents a compelling ROI for budget-conscious organizations seeking feature-rich solutions. Amazon WorkMail, though more costly, is valued for its integration capabilities and security, often leading to greater long-term benefits. Zimbra Collaboration's initial cost-effectiveness is clear, yet Amazon WorkMail might deliver better long-term value for businesses focused on security and integration.

Centralized email accounts have streamlined routing, security checks, and long-term organization

While using Amazon WorkMail over time, I haven't encountered substantial disappointments, but there have been usual glitches with the web interface. For instance, while the service is generally 99.5% perfect, I experience issues like the folder structure I set up sometimes not remembering the state of expanded and collapsed nodes after refreshing the page. This lack of persistence in which nodes are collapsed or opened can be frustrating. However, since it's a minor technical issue, I doubt the average user would notice it. If Amazon WorkMail were not discontinuing, I wouldn't think there is much to improve or enhance about it. It is standard enough and easy to use, and any glitches are minor, not worth evolving or disrupting its current functionality. As for whether the user interface is intuitive and if I'm satisfied with its flexibility and customizability, there are some minor features lacking, but I don't feel a need for changes since it works as designed. The most crucial aspect is that I can set up my address book with the complex organizational structure needed for the accounts connecting to AWS. The lower-level functionalities suit me well enough. Other services often have customizable views of email representations with senders, subjects, and even snippets of content. While my external application on mobile can show customizable lines with my email list, Amazon WorkMail does not offer that feature. I don't really need it, but it would be a nice addition for power users.

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 product is very user-friendly."

"The encryption of emails, both in transit and at rest, has benefited our security strategy as it is a layer of security that provides us better confidence for customers and also internally tracks the security aspects."

"The most valuable feature of the Amazon WorkMail for me is the SMC server. It makes my work much easier, especially since I often work with Spring Boot. There are many built-in APIs in Spring Boot that help with messaging. What I appreciate about it is that it simplifies the process. I don't need to write much code; I define the credentials in my properties or environment variables. The Java Message API, an internal API from Spring Boot, does most of the work. I set up the properties and connected them to the SMC server, and I can send emails."

"It is very stable. I haven't faced any issues."

"We use the tool for transactional emails and marketing."

"It is highly available and scalable. It is also highly reliable. I don't lose any of the messages or emails. If there is an issue where the email sent operation failed, Amazon as a platform ensures that the send operation is retried, and the email reaches its destination. This way, it is highly reliable."

"Amazon SES is very easy to configure."

"We have cut our costs in half."

More Amazon WorkMail pros

"Good email solution and it's open-source."

"For a small company, Zimbra Collaboration is good because it is simple, inexpensive, and not very difficult to deploy."

"The backup and storage management features of Zimbra Collaboration are valuable."

"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."

"The Zimbra Collaboration's most valuable feature is web access."

"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 logs, troubleshooting, and tracking we have found to be the most valuable features, and when we have any issues with lost messages these features are useful because it is very easy to track and log."

"One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."

Cons

"Amazon WorkMail's user interface could be more intuitive and user-friendly."

"If we can have a completely managed backup solution where we have a tiered backup or a tiered archival to be able to retrieve emails, it would be great."

"Now, I'm not very happy because they are discontinuing the service, and I will have to find a new one to migrate everything, including all my filters and routing rules."

"It would be nice if they had a what you say is what you get editor to build newsletters like MailChimp has."

"Email service is definitely a requirement from an enterprise standpoint. Many organizations have their own on-premise email services, which take a lot of memory, backup, and other resources. If we can have a completely managed backup solution where we have a tiered backup or a tiered archival to be able to retrieve emails, it would be great. I would like to be able to retrieve emails in real-time (hot retrieval), over the 90-days period (warm retrieval), and over the one-year period (cold retrieval). It would be useful to have tiered backup and retrieval. It would help us in managing emails better and have a better backup solution. So, backup is something that we require."

"The product should improve technical support."

"When we first set up an email on Amazon SES, they had to verify it, which was not fast enough."

"There is room for improvement in the support. It's just that customer support, though good, takes time to resolve issues."

More Amazon WorkMail cons

"The solution’s forums don't have much information or documentation on administration tasks."

"There can be difficulties resolving problems on the server side when problems arise."

"The installation is not straightforward, it can take two days for the full implementation."

"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."

"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."

"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."

"It does have a few bugs."

"It would be great if a group chat feature were created to allow for a team environment."

More Zimbra Collaboration cons

Pricing and Cost Advice

"I rate the solution's pricing as one out of ten. It is close to being cheap. Sometimes, the tool offers a generous amount of free messages, up to 40,000, which is great for startups like ours. This means that we don't accumulate any costs for some months because we stay within the free usage tier. When we exceed the free allocation, the costs are reasonable, and no hidden charges exist."

"It's very cheap. The cheapest among all the services available."

"The solution should improve its price."

"WorkMail does require a license, it is, per user."

"The solution is not expensive compared to other products."

"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."

"We do not pay for licenses to use this solution."

"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."

"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 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."

"Zimbra Collaboration offers a good price-to-feature ratio."
