Provides free messages and helps to keep customers updated
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. I would only suggest that Amazon WorkMail relax the rules for using Amazon SES in production. When you create an account, it starts in Sandbox mode, which means you can't use it in production right away. You must go through a process, message Amazon, and request to move it to production. Since Amazon is a big company, I feel customers shouldn't need this permission to use the service in production.

Offers good user interface and seamlessly integrates with other Microsoft services
I like its user interface. I don't struggle or face any challenges while using it. The design interface is simple. I haven't had any trouble managing it for a long time. Even if I encounter a challenge or two, I can always reach out to Microsoft for help. So, overall, it's been a very positive experience. Having everything under one account was valuable. I just had to go through cybersecurity for licensing and download everything. With one account, you can download Office and use Online features directly from your Exchange. There are security solutions in place, and we take customer data very seriously. For example, if I accidentally create a forwarding rule or send an email with an image attached, I get a notification immediately. Compliance-wise, it's quite good online. We can do many things. Even if I can't click on something or upload a specific file type, it'll still be stored for compliance or investigation purposes. So, subscribing to these features. The benefits are widespread and effective communication. We use Microsoft Teams for meetings within and outside our organization. Additionally, Teams can be used for chat, allowing us to track communication and see user activity. Those are the key points that have proven to be beneficial.

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."
"The most valuable thing is that emails sent through SES have a delivery rate of greater than ninety percent."
"There is no need for me to set up security."
"We use the tool for transactional emails and marketing."
"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 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."
"The best feature is that Amazon SES provides verified email messages."
"The product is very user-friendly."
"Exchange Online is a straightforward cloud-based application. It's easy to connect and the interface is user friendly."
"A valuable feature of the solution is its global usability."
"Microsoft Exchange Online is easy to use. You have a common storage where people can store documents. It also helps with version control."
"The most valuable features of Microsoft Exchange Online are the frequent updates. They upgrade and optimize the features to make them better and better. They have a very strong ecosystem and they integrate together."
"When you used to write to someone, you would often begin typing their name and their email address would appear; you would simply click and you would have the correct email address. That has been working for a while, but having the location address appear was a pleasant surprise. It was amazing."
"Stability has increased exponentially since 2010."
"We also create technical presentations, so most of the time we are dealing with MS Word and Excel. Sometimes, we also use Visio for diagramming. Our overall experience is good."
"The most valuable feature of the solution is its integration with Microsoft Outlook and Microsoft Teams for shared calendars."
 

Cons

"There is room for improvement in the support. It's just that customer support, though good, takes time to resolve issues."
"The only issue is the price, which is far too expensive."
"The product should improve technical support."
"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."
"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."
"Amazon WorkMail's user interface could be more intuitive and user-friendly."
"WorkMail is not available in all the regions."
"I would like to see detailed reports on email success and failure rates."
"For example, recently there were some spam incidents that Microsoft does not currently mitigate because they have another paid solution to do so. It would be nice to integrate the security and the anti-spam (i.e. the fake links, etc.) along with the Exchange Online default."
"This solution involves a lot of work for an administrator. It is not always easy to find exactly what you are looking for within the system."
"The UI could be improved to look more like the desktop version for ease of use."
"Documentation is lacking."
"Improving the methods for inputting email signatures could be beneficial for the product."
"When we need to purchase additional licenses for additional users, the process is slow."
"The efficiency could improved."
"Also, I think the mobile app on the forms you can improve a little bit more."
 

Pricing and Cost Advice

"WorkMail does require a license, it is, per user."
"It's very cheap. The cheapest among all the services available."
"The solution should improve its price."
"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 is a cluster solution."
"The solution costs $12 to $16 per user per month."
"There is a license for Microsoft Exchange Online and I have information on that, but there have been so many changes to the licensing and it's a completely different story nowadays. Microsoft has been pushing users to buy a package of products under one license. Users are becoming more dependent on Microsoft rather than independent, that you can't decide anymore, and from my point of view, that is bad."
"We bought some licenses, and some are within our package or partnership with Microsoft."
"The model is one which is pay-per-use go. There is no license. We are talking about per-user subscription-based use."
"The pricing for this solution is good. We renew our contract every three years. I would rate the pricing for this solution a three out of five."
"We have an enterprise agreement for licensing."
"We pay a yearly licensing fee for the solution."
