The most thing I like about Amazon SES is that it's high deliverability rate, ensuring that emails reach recipients inboxes without being marked as spam.

AWS Solution Architecture

Amazon SES offers reliable email delivery with high scalability and strong integration with AWS services at a cost-effective price.

Amazon SES has a complex setup with strict email-sending policies, and achieving high deliverability requires careful configuration and monitoring.

Operations Manager

Our company has gotten good feedback from our clients from our company's use of Amazon SES for sending transactional emails for our clients.

Director

It can also handle small to massive volumes of emails without any performance issues.

Amazon SES is a cost-effective and scalable email service with strong AWS integration.

The most difficult part for me was the set up it was confusing while in that process. After we got though that it seems to be much smoother and going great now

Travel Agent

I'm always in the know of services that they have available and if I'm eligible, and I'm always updated about Prime membership, and more.

Account Manager

I wish there was a default feature to correct this.

Sales manager

The redemption of their cards into cash is not acceptable

Initially you are sandboxed and have to apply to have this removed manually.  

Lead Engineer

Little bit setup becomes hard for this and price is little high.

The platform is user friendly and easy to navigate, making it simple to set up and manage email campaigns.

Web Designer

I need approval for production use in this.

IT Manager

Amazon SES makes a determined email marketing assistance for companies, and it saves on communications costs.

It is simple to set up and use (integrated with Laravel) and other AWS services.

Chief

I am a user for a few monthd and i used to have problemas with mail delivery, but It really helped me to improve my email campaigns

Engineer

Editor

The worst part is the customer service of amazon ses, once they blocked from sending campaign for any reason but when you asked for appropriate reason for blocking account, they just simply used canned response some time you feel that robot are working there instead of human

Trainer

It will help lot of customer dealing with questions and emails.

As of this writing, we are talking about $0.10 per 1k emails sent, which is really now.

Niche Growth Facilitator

The email reputation for my domain (and client domains) was poor and needed to be relayed though a trusted provider with higher reputations.

Deliverability is good, and dedicated IP pricing is very low.

Sr Email Marketing Manager

Due to the fact that it provides good reputed IP addresses, our emails do not end up in SPAM folders.

The email notification are sent using Amazon Simple Email Service, which is a cloud based email service.

Support is pretty weak, as with all of AWS.

I have used the service earlier around 4 to 5 years, it was profitable to small business, due to cheap marketing plan and all the IPs are very effective

Medica recorder

Teaching Assistant

This is because Amazon SES has email sending statistics which includes the statistics of feedback rates, bounces rates, and deliveries rates.

online marketing

the ability to send emails per minute is super goodthe economics of the service.

Team Lead of Internal Tools

We even use SES to send reports to our departments with all the errors from SES the previous day (like updating email addresses in our system if they bounce)

One thing I thought could be improved was the allowed size of  each email message was too small.

Project Management Consultant

The initial set-up requires some patience, tinkering and you even need an external app to increase its functionality.

web developer

This can be particularly important for businesses that rely on email marketing campaigns to reach customers.

This could result in a steep learning curve for users who are not familiar with AWS and its various services.

We are required to save copies of outbound communications for some of the messaging and we have to get around this by using an email account as an 'archive email'.

the documentation sometimes doesn't help.the desktop board is very unfriendly.

Software Engineer

A bit too expensive for our use case so we switched to a competitor

Human Resource Manager

The deployment of Amazon SES has been so easy.

Deliverability is decent, not the best but I don't argue because it's really the most affordable way to do so.

Development Manager

Straightforward service; very cost effective for low/medium volumes of email

The cost of this solution is much lower that that of the most other solutions in the market.

It is the way to go when you want to have bulk email at a fraction of the costs incurred with other competitors.

I've used it for multiple different projects utilising both API and SMTP connectivity and both have been solid.

By using Amazon SES, my company can send emails to our customers efficiently.

Three features are most impactful to my business.

I liked that it was fairly easy to set up, and there were a lot of "how to" guides available.

Software Engineer 

It takes long for domains to be verified after adding the required TXT records in the DNS and even after the domain has been verified, you have to apply for the usage limits to be removed which also takes time.

The pricing is amazing and whilst you don't get all the bells and whistles other more fully featured services offer it does what it says on the tin.

We previously had a self hosted email server we were using but wanted to upgrade to something cloud based and secure.

Retired Homeopath

I appreciate the ability to save emails in folders of my choice.

Emails do not display .webp images, this is very annoying.

flexibilty and easy to use, also the custom tags that you can add

Translator

No problem at all to check and read mail...

Producer

Also, it does not separate clearly how old emails are, it would be great to have a divider between each day's emails,  just so it shows more clearly.

founder

Additionally, the software integrates with popular productivity tools, such as zapier, dropbox, etc, making it easy to manage emails in the context of other tasks and projects.

I can make changes to suit my needs very quickly, without having to navigate a whole load of items that are not required.  

President

Very easy and clear to use, grouping of email addresses by function, grreat archiving of emails (more than 10 years for us)

Simple to use, great to separate work and personal emails

Owner

I love that you can add RSS feeds right there in your mail box.

Overall, Postbox is a powerful and customizable email client that offers a wide range of tools to help users manage their inboxes.

Marketing Manager

Having e-mail addresses from our three domains, two businesses and personal e-mail, makes this a life saver, and something not possible in Oulook 2019.

Bookkeeper

Great email client for both imap and pop accounts

Ph.D. Student

They are saying they would refund the fee, if your problem is due to a bug, but still it does not make sense to get a support from a paid app with an extra fee.

owner

very reliable and customizable, never lost a mail in 10 years

As somebody who has cerebral palsy, the scroll bars implemented in v. 7 of Postbox slow me down, and are unnecessary.

The cost is what I like least about Postbox.

sound engineer

stars for developers and for Customer Service that hepled me from time to time with new features and some minor problem with my system (for example my fonts on windows crushed and CS helped me to find solution althrough it was not their job, e-mails with Georgia font was problematic).

Nothing

Product Designer

Most of the time, I am working on my emails on my Mac, therefore I decided to go on the hunt for a powerful email client to work through my open emails. Since ProtonMail uses end-to-end encryption there are very few email clients available that can be used with a ProtonMail account.

Engineering Consultant

The clearly and logical structured user interface that never leaves you wondering where the function you are looking for might be hidden.

Retired engineer - future home inspector 

Signature block location in email replies or  when forwarding emails.

The lack of read receipt options is also a major let down, and somewhat surprising.

They also have a lifetime license option and the app is continuously receiving updates.

Distinguished Service Professor

I've used Postbox for many years, but as my number of saved emails has accumulated, I need to be able to categorize them individually so this "feature" is increasingly leading me to consider other email software options.  

Simple, fast, with all things you really need.

I like that it is very user-friendly, simple to use and does what I need.  

So far cannot find a way to import my contacts from the terrible eM client!

I have tried all mail clients on MAcOS, but Postbox remains the best.

Administrator

A big advantage is a very good "3-pane-view" and the quick filters for "unread" or "with attachement" or VIP persons.

The most annoying feature for me is that selecting a topic for a message will add that topic to the entire message conversation.  

They try to charge you $8 per incident for the support.

They provide student discounts which is a big plus.

investor

Like all third party products, occasional glitches with Apple and/or Google mail servers, since Apple and Google don't always closely follow all the IMAP rules.

Retired

The tiny little line at the bottom of the screen is very hard to read!

I then moved email accounts to Gmail and that also comes with it's limits and I was not always sure that my emails were arriving.

Online Educator

Postbox has allowed me to aggregate all of my email messaging into one place and keep my messages and attachments all organized in one easy-to-use and reliable local work area.

English Teacher

The fact that the junk mail does not work well and still puts categorized mail in junk.

manager

More ideal if it worked hand in hand with particular mail-servers to enable config sharing for web-mail and/or client scriptability and custom columns similar to how Directory Opus does for Windows Desktop.

I have compared this product to the defunct IncrediMail.
