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.

Our customers are able to use this groupware solution to connect to Active Directory and OpenLDAP, although Postgres support would be an improvement.
Zarafa has several very valuable features, among them a very good Outlook-like web interface. Furthermore, ZPush for talking between ActiveSync and mobile devices is a valuable asset. In addition, one is able to connect via Outlook and the exchange protocol to Zarafa. This makes Zarafa a free, and working, alternative to Microsoft Exchange.

Quotes from Members

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

Pros

"The most valuable thing is that emails sent through SES have a delivery rate of greater than ninety percent."
"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 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 product is very user-friendly."
"The best feature is that Amazon SES provides verified email messages."
"We use the tool for transactional emails and marketing."
"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 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."
"This makes Zarafa a free, and working, alternative to Microsoft Exchange."
 

Cons

"There is room for improvement in the support. It's just that customer support, though good, takes time to resolve issues."
"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."
"It would be nice if they had a what you say is what you get editor to build newsletters like MailChimp has."
"WorkMail is not available in all the regions."
"There is room for improvement in the scalability."
"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."
"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."
"Not really, although the Zarafa-index component was using a lot of memory and disk I/O bandwith."
 

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."
