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.

Trust and anonymity play a key role in secure communications
I am uncertain about the two-factor authentication feature. I have had integrations with other Proton services and have used Proton VPN once, though it has limited features. Simple Mail, which was acquired by ProtonMail, has been very useful for me. The pricing is moderate. I have not used any paid services from ProtonMail. It is not very costly, but I have not used any premium services. I am a customer of ProtonMail. I would rate ProtonMail an eight out of ten due to their transparency and the utility of their simple login feature. My job and company name should remain hidden.

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."
"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."
"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."
"WorkMail works very well, and the functionality is fine."
"Amazon SES is very easy to configure."
"There is no need for me to set up security."
"It is very stable. I haven't faced any issues."
"ProtonMail is cost-effective for encrypted mailing, offering extensive features and customization, especially if you want to provide your own hashing and keys."
"What I appreciate most about ProtonMail is that they are trusted, which is why I choose them."
"The auto encryption of attachments is valuable."
 

Cons

"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."
"There is room for improvement in the support. It's just that customer support, though good, takes time to resolve issues."
"The product should improve technical support."
"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."
"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."
"When we first set up an email on Amazon SES, they had to verify it, which was not fast enough."
"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."
"I think it is good but I feel that only tech-savvy people use ProtonMail. It is not that popular among other people."
"One improvement could be the integration between ProtonMail and Proton Pass, allowing sharing of specific secrets via email."
 

Pricing and Cost Advice

"The solution should improve its price."
"It's very cheap. The cheapest among all the services available."
"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."
