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.

A scalable and easy-to-use solution that has a good user interface and a responsive support team
The product had a couple of bugs. However, the vendor resolved the bugs quickly. People wanting to use the solution must try it out. If they like it, they can switch it on. I have seen and tried many other products. ZeptoMail is pretty easy and straightforward. Overall, I rate the tool 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

"Amazon SES can handle a high volume of emails, making it suitable for organizations with large email lists or that need to send a large number of emails on a regular basis."
"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."
"WorkMail works very well, and the functionality is fine."
"Despite being an end-user service on AWS, the backend is complex enough to enable many useful features, I invested time in configuring it, and it worked flawlessly for six years."
"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."
"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."
"The user interface is valuable to me."
 

Cons

"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."
"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."
"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."
"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."
"The only issue is the price, which is far too expensive."
"WorkMail is not available in all the regions."
"We are losing clients because the price my clients pay for email alone is nearly equal to the price they pay for an entire Microsoft Office license, which includes email."
"We had some minor bugs."
 

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."
"The solution should improve its price."
"WorkMail does require a license, it is, per user."
"It's very cheap. The cheapest among all the services available."
"The solution is the cheapest in the market."
