Executive SummaryUpdated on May 21, 2025

KerioConnect and Amazon WorkMail compete in the email and collaboration category. KerioConnect tends to have more satisfied users regarding pricing and support, while Amazon WorkMail excels with its comprehensive feature set, justifying its cost.

Features: KerioConnect's valuable features include robust security options, integrated antivirus and antispam, and flexible deployment options. Amazon WorkMail is recognized for seamless integration with AWS services, advanced mobile access features, and broader cloud capabilities.

Room for Improvement: KerioConnect could enhance its cloud integration, mobile app functionality, and scalability. Amazon WorkMail may improve by addressing its learning curve, increasing support for non-AWS integrations, and simplifying its user interface.

Ease of Deployment and Customer Service: KerioConnect offers a straightforward installation with options for on-premises or cloud deployment, supported by responsive customer service.

Seamless email communication improves cost-effectiveness and security with valuable tracking features

The features of Amazon WorkMail that I have found the most valuable so far include sending emails and tracking whether the email is read or not. I find the feature that checks how many emails have been successfully sent and how many of them have been opened very useful, because in our application, we know the usage of the emails. 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 encryption meets my expectations.

Lightweight, simple, and robust; easy to maintain and doesn't require a lot of system resources to run

Kerio Connect does as advertised, so there are no real issues with the product itself. It's developed regularly, so there are constant updates. Possibly, the support and development have lessened since they've sold the company, but as far as the product itself is concerned, there isn't anything that I would suggest needs improvement. If I'm being picky, Kerio Connect uses a proprietary, mappy atom for Outlook, and it would be nice if they used a native mappy connection instead, but that's the only additional feature that I would like to see in its next release. If they have native Outlook map integration, that would be great, but other than that, it's got all the functions that I think a mail server should have.

Quotes from Members

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

Pros

"Amazon WorkMail integrates with Route 53 and other AWS services, providing a seamless experience when using AWS infrastructure."

"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."

"There is no need for me to set up security."

"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."

"The best feature is that Amazon SES provides verified email messages."

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

"The most valuable thing is that emails sent through SES have a delivery rate of greater than ninety percent."

"Amazon SES is very easy to configure."

More Amazon WorkMail pros

"The solution is easy to maintain, unlike Exchange. It's easy to create multiple domains and back up and restore if needed. It also has good security features like anti-spam and antivirus."

"We have contacted technical support a handful of times and received some assistance."

"It's relatively simple to use."

"We use the solution as a mail server. It connects with Outlook and is used for calendaring and similar tasks."

"The most valuable features are security and privacy because you installed it on your server, within your company premises, not in the cloud."

"Kerio Connect is secure, flexible, and easy to control from the user interface. It has many security features able to be controlled from one place, such as anti-spam. I have found it very convenient. Additionally, you can analyze log files and share folders which is helpful."

"What I like most about Kerio Connect is that it supports ActiveSync, and that is its most critical feature. The solution is also a nice, simple, robust, and stable mail server."

"The user interface is good."

More KerioConnect pros

Cons

"The only issue is the price, which is far too expensive."

"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."

"WorkMail is not available in all the regions."

"The solution is quite low-level and lacks some advanced features. For example, it doesn't provide tracking capabilities, such as knowing how many users opened an email, which is crucial for email marketing. You would need to integrate these analytics with other tools to get them. I need to know if there has been a bounce and how customers interacted with the email."

"It would be ideal to have detailed data and reporting on email opens, clicks, bounces, and other metrics, as well as integration with other business intelligence tools."

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

"I would like to see detailed reports on email success and failure rates."

"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 could improve the redundancy because we only have one copy of the Kerio Connect server on our hardware. The next step for us is to move to the cloud and if Kerio does not have a cloud version available they should release one"

"I would like to see better support from their support team."

"Having a native Outlook map integration would make Kerio Connect better."

"The search and archiving documentation capabilities need to be stronger."

"It could be simpler to use and install, but I still wouldn't use it because there isn't a compelling use case."

"Most of our clients use Outlook and Kerio Connect. Occasionally, Kerio can be a bit slow. They could make it faster to get onto the web interface without so much load time. It's just slow with Outlook, however, for some reason."

"KerioConnect continues to improve with regular updates throughout the year. They must be added to the roadmap, which requires approval."

"We are considering switching to Microsoft Exchange. One reason is that it doesn't improve our workflow and doesn't integrate well with Microsoft 365 applications."

More KerioConnect 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."

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

"The solution should improve its price."

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

"KerioConnect has a first-time cost and yearly subscription. It is not expensive."

"The pricing is about $3 per mailbox per month."

"The price of Kerio Connect is better when comparing it to others solutions."

"The solution's pricing depends on how long you plan to keep it because you pay on a per-year basis. You might have a one-time setup cost for something like Microsoft Exchange or a Linux mail server. I'd say this solution is expensive on a per-year basis, almost 2000-3000 dollars annually. It doesn't seem to pay off yet, so we're considering switching to another product."
