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.

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

"The best feature is that Amazon SES provides verified email messages."
"The product is very user-friendly."
"It is very stable. I haven't faced any issues."
"Amazon SES is very easy to configure."
"The most valuable thing is that emails sent through SES have a delivery rate of greater than ninety percent."
"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."
"We use the tool for transactional emails and marketing."
"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 user interface is valuable to me."
 

Cons

"When we first set up an email on Amazon SES, they had to verify it, which was not fast enough."
"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."
"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."
"Amazon WorkMail's user interface could be more intuitive and user-friendly."
"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."
"We had some minor bugs."
 

Pricing and Cost Advice

"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."
"It's very cheap. The cheapest among all the services available."
"The solution is the cheapest in the market."
