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.

Quotes from Members

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

Pros

"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."
"The product is very user-friendly."
"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."
"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."
"Amazon WorkMail integrates with Route 53 and other AWS services, providing a seamless experience when using AWS infrastructure."
"Mailgun is cheap, secure, fast, and simple."
"It's a very easy product to set up."
"I haven't been required to pay yet because they give me 10k free emails per month, so for medium emails, it's the best choice."
 

Cons

"When we first set up an email on Amazon SES, they had to verify it, which was not fast enough."
"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."
"There is room for improvement in the support. It's just that customer support, though good, takes time to resolve issues."
"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."
"I would like to see detailed reports on email success and failure rates."
"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."
"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."
"The product should improve technical support."
"The solution needs better templating and email validation."
"Mailgun doesn't have this."
"Preview of email as sent - currently, the preview is an image."
 

Pricing and Cost Advice

"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."
"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."
"We pay $80 a month to use the solution."
