Pros:

Postbox includes a wide range of tools that help users manage their inboxes, such as filters, tags, and folders, allowing users to quickly find and organize their emails.

Cons:

For some reason, Postbox fails to see it. Is there anyone at Postbox, to whom I've paid for the app, to contact about this.

Manage your email in a professional way

5.0 3 years ago

Comments: My overall experience has been really satisfactory, being able to take my email management to another level. Labeling and filing in an easy, fast and productive way. Easily searching for all my information.

Pros:

All the features are great, maybe because it is super intuitive (Thunderbird style). I have wanted to pay for it, because it had special features that have made my email handling efficient and productive.

Cons:

I honestly don't see any missing function.

Conventional scroll bars - yes, non disabled people can use them without the need for counselling

3.0 2 years ago

Comments: I think I have made my point, but other issues... The merging of Postbox v. 7 and Outlook 2019 would provide the ultimate e-mail management application. Once Postbox Inc. staff extricate their heads from the sand, they could have a much better product.

Pros:

I really do like the smart folders, and the ease at which they can be created. 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.

Cons:

As somebody who has cerebral palsy, the scroll bars implemented in v. 7 of Postbox slow me down, and are unnecessary. Suggesting that non-disabled people cannot use conventional scroll bars is insulting, and if I were non-disabled, I would be questioning Postbox Inc's low opinion of me and others like me. Encryption should be easier to setup, and not to be able to schedule a date and time for specific e-mails to be sent appears to be a glaring omission, as is the inability to insert a signature at the cursor. The lack of read receipt options is also a major let down, and somewhat surprising.

Postbox a good experience!

4.0 3 months ago

Comments: The email client stands out with its intuitive interface and powerful features designed to enhance productivity. Navigating through emails is a breeze, thanks to its clean layout and efficient organization tools. The customizable tagging and labeling options allow for seamless email management, making it easy to prioritize and sort messages. Postbox's advanced search functionality ensures that finding specific emails or attachments is quick and effortless.

Pros:

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

Cons:

Emails do not display .webp images, this is very annoying. I send a feature request to Postbox

Overall good product but with a few annoyances

5.0 3 years ago

Comments: Overall, my experience has been positive. It would be nice to be able to request a feature and receive a response from Postbox staff as to whether there is any possibility of implementation.

Pros:

Postbox is relatively easy to use. The overall interface and design are well-done, which contributes to ease of use. Postbox has powerful search features and searches are rapid, after initial indexing has occurred. The ability to quickly filter by contact name or by other message characteristics is also very nice. Displaying just the names of attachments and being able to quickly review them is a big plus.

Cons:

The most annoying feature for me is that selecting a topic for a message will add that topic to the entire message conversation. Often I want to tag different emails in the conversation with a different topic tag but this isn't possible. 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.

The best, its a nice surprise

5.0 9 months ago

Comments: Simple, fast, with all things you really need.

Pros:

I thought the download was just a generic email manager, but when I started to configure it, I realized that I'm not a technician and don't usually work with these kinds of things. I just have too many emails to manage. To my surprise, after 15 minutes of following the site's instructions, everything was done. All my emails were separated into folders with auto filters. I didn't encounter any difficulties, so I gladly paid for it and supported the developers.

Cons:

"Don't have AI support. The interface is a little confusing in the beginning, but it is customizable."

Feature packed but simple to use

5.0 8 months ago

Comments: Very easy to set up. Simple to add accounts. Loads of features for the more advanced user. Just works.

Pros:

Easy to get started but there a loads of features which become more useful as you use it more. I tried a lot of email clients before finding Postbox.

Cons:

I find the name difficult to remember! Very ocassional oddity with bullet points.

Pros:

Ease of use, available options, visual styles

Cons:

There is nothing that I can think of that it doesn't do

Streamlinec communications for the multi-preneur

5.0 5 years ago

Comments: As a user with multiple projects for multiple enterprises going at the same time, I found myself missing communications or misplacing threads because of the sheer volume. Postbox has helped me to better navigate the deluge of email communications that I receive, and to filter what is necessary to focus on now and what can be stored away. I appreciate the tagging and image search features especially.

Pros:

The ability to combine all of my email inboxes intelligently, with deep search and filtering capabilities that help me to not miss anything from my various projects.

Cons:

Would love to be able to extend these functionalities to my iOs devices

I can't function without Postbox!

5.0 5 years ago

Comments: My job requires reading, accurately filing away, and responding to hundreds of email messages each business day. I've used dozens of other email clients and none of them can hold a candle to Postbox. For better or worse, I am hopelessly addicted to this tool.

Pros:

There are so many features that Postbox has that I depend on day to day, I'm not sure where to start. I think the most useful for me personally is the ability to color-code messages and assign topics to them. "Accounting" is green. "Contracts" are orange. "Urgent" is red. "Publicity" is fuchsia. It's simple to categorize my email by urgency and topic this way. After that, the quick-move feature that also exists in the Gmail web interface that allows you to easily label and file/archive messages is great. They expanded that with the new "copy" feature which I am also using a lot. Even some of the lesser-used but advanced features quickly come around as must-haves. One example is the new "clips" feature, which allows you to easily stylize outgoing messages to really let your emails stand apart from others in a long email chain. It's very useful. With the new version 7, we can also choose from a number of attractive themes which make the interface look very slick.

Cons:

I have experienced some instability from time to time, but to be fair, I run about a half dozen separate email accounts consisting of hundreds of thousands of messages through Postbox every day. I also noticed that the software became much more stable after I upgraded to MacOS Mojave from High Sierra, so these matters were apparently not Postbox related, but instead OS related. To be honest, I have few complaints about the software, and the few times I have ever had to contact support, they have been extremely responsive and helpful.

Postbox for selfemployed users

5.0 3 years ago

Comments: I manage all my business and private mails. And that does Postbox very good. It is much better than Outlook and a little bit better than Mozilla Thunderbird in the usability. But the other two have the better groupware and collaboration features (with add-ons).

Pros:

In Postbox I like how easy it is to manage a lot of mailboxes (to group them for example in "business" or "private"). A big advantage is a very good "3-pane-view" and the quick filters for "unread" or "with attachement" or VIP persons. Then it is very easy to forward received attachements in a new mail with this sidebar in the compose window where you can see the last received attachements.

Cons:

For business use I miss two things really much: integration of CardDAV to use my contacts that are stored in my private Nextcloud. So at the moment I have in Postbox different contacts than on my smartphone and tablet. And I miss also the CalDAV integration with an internal calendar. Some years ago there was a calendar add-on. So it is difficult to save or accept invitations directly to a calendar. Maybe a task management would also be nice (also together with the Nextcloud server).

I think this is the best email client available

5.0 5 years ago

Comments: I'm extremely happy with this client. When you are using an app nearly all day, you'd better love your email program. They get everything right.

Pros:

I've been using email clients daily since Netscape days in the 90s. I think this is, by far, the best and most full-featured email program available today. I've worked with/tried many over the years. Particularly great is the "Responses" feature, that allows you to insert saved email snippets. I use it dozens of times a week to simplify my outgoing correspondence. If you've been agonizing about which client to use, I think I can save you a bunch of time (as I agonized, too). Very happy with this client--have been using now for about 4 years.

Cons:

I've had an older version for awhile (I have an older Mac OS to preserve using some expensive design software), and they only provide online tech support for the most current version. But I'm running the most current version on another computer and it's very responsive online support.

The email app for power users.

4.0 2 years ago

Pros:

I have been using Postbox on my Mac for over a year now and it is without a doubt one of the most powerful email clients out there. Since I am a privacy advocate I am using ProtonMail for my personal and professional email. ProtonMail is currently available as a web app, and for Android and iOS. That means there is no dedicated Mac App available. 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. One of them is Postbox. Postbox features a beautiful, clear, lucid, and modern interface. One of my favorite Postbox features are the power to group my accounts, view email in tabs, the search with advanced queries, and of course the quick bar to perform any kind of actions with just a few keystrokes.

Cons:

Although Postbox is a lovely piece of software, I would say it is mainly aimed at people who are writing loads of emails, people who are power users. For casual email workflows you probably do not need all the features Postbox is offering, and therefore you might take a look at alternatives. But if you are on the hunt for a desktop client for your ProtonMail account you should definitely take a look at Postbox.

Simplifies my email

5.0 last year

Pros:

I have used Postbox since before gmail was so common. I originally kept an archive of all my emails. It became onerous on my old computer. When I got a new computer, I didn't install Postbox immediately, and tried other programs. I really missed the threading, the signature, the search, and the ability to flag messages. I reinstalled Postbox after trying other programs and I can't believe how much easier it is to handle email. I am no longer archiving messages on my computer, but am using a cloud service. The speed issue has disappeared.

Cons:

I have no complaints at this point in time.

Hands down the best email client I’ve ever used

5.0 5 years ago

Comments: After using outlook this was an introduction to software done right!
Straight away it just made sense! It never gets in the way! I have a very large in box and the app never slows down!
Even on my old iMac with a standard HD it’s nippy!

Pros:

This is email sorted! I’ve used multiple different email clients and postbox was a lucky find being included with a bundle of software that I bought years ago I loved it so much when v4 came out I bought a lifetime license and I am over the moon that I did! As this app just gets better and better! This is designed by people that use email!

Cons:

It’s a very small thing I’d just like the reminders to be date aware so I get a prompt for my ageing brain to do things!

Postbox mail client

5.0 2 years ago

Comments: No issues at all, in fact fixed issues I had with other clients.

Pros:

Switched to Proton Mail and used with Thunderbird, emClient, Mailbird, all had issues. Discovered Postbox and worked perfectly with Proton. Not only that but blown away by just how good this client is, best of the best in my opinion.

Cons:

Nothing except would like an 'Undo Send' option (delay for say 20 seconds), have submitted as a feature request... pretty pretty please!

I Like It Because It Works

5.0 5 years ago

Comments: I use it primarily for reading, organizing and sorting my daily Emails - I use several hosts, which has been problematic with other email clients I've tried - but Postbox seems to work with all of them.

Pros:

I was looking for a mail client that was easy to install, set-up and rely on and Postbox has checked all the boxes. I use several hosts (iPage, Hostmonster, Gmail, Mac mail) and it works with all of them. In addition, they are always working to make it better. Nothing is more frustrating than a mail client that doesn't do what it is supposed to, or takes forever to get to work right. Not so with Postbox. I was an early adopter, and while there were a few issues early on, it just keeps getting better.

Cons:

A few issues early on, but the most recent version has been very solid.

Everythings fine and I wouln'd change the software ever

5.0 4 years ago

Comments: I use postbox nearly 7 years now and its one of the best e-mail-clients I have managed over the years. I have many customers with problems on their clients, so I have access to many of them. Support and Service - 5 Stars Usage and UX - 5 Stars Handling of over 1 million emails - running smooth - 5 Stars All my clients to whom I recommended Postbox are also very satisfied and happy to have parted with their previous client. Thx2Postbox Team!

Pros:

Its doing exactly this what a email-client have to do -> manage accounts, receiving and sending emails. Next is the UX and easy handling of everything.

Cons:

pffff can't tell. There is nothing I don't like

Awesome email program

5.0 5 years ago

Comments: My overall experience with Postbox has been very positive. I've been able to work with my multiple business emails as well as my personal emails, in a quick, efficient manner. Everything is handy and right on the screen and I don't have to dig around to respond to clients from different areas of my work. All and all, I've been super pleased with it's functionality as well as it's ease of use. And? It doesn't hurt my eyes to check and work in my email (GREAT BONUS!) It's a beautiful program.

Pros:

Seriously, I have had nothing but great success with this software. It's super simple to set up, easy to navigate, has a great interface that's pleasing to work with.. and on top of all of that? Super affordable. I couldn't be happier.

Cons:

I really haven't found anything to complain about.

Postbox: My Correspondence Manager

4.0 4 years ago

Comments: First I like the ease of use. I know I haven't scratched the surface on all the Postbox provides and I am making the usual mistakes that a learner makes . I like the appearance. I like the speed.

Pros:

Because of my position as pastor, plus my personal correspondence and personal writing aspirations and believe it or not still studying it was necessary that I have several email addresses. This got to be rather copious until I found a provider that serviced my emails under one roof. Unfortunately this service became rather unpredictable not always giving me access to my email boxes so I began the hard search for a similiar service.

Cons:

I am from the old school and when I had a registration problem I had trouble getting someone to respond. I have had a long working career, ie transportation, customer service, Social Services, the church and I like to have a means to get a hold of someone to listen and help. But persistence paid off I got the help I needed. And I have to consider that we are in a very unique unpredictable time right now. Bottom line.....I got the help I needed.

I keep coming back to PostBox

Comments: I am a Mac user. I've used Apple Mail, Outlook, Thunderbird and almost every other client there is around. I keep coming back to Postbox - it never loses an email, or decides to not connect to my server (are you listening Apple Mail?) is reliable, works great with SaneBox.

Pros:

The way it handles multiple accounts cleanly.

Cons:

The inability to change themes from the pre-packaged.

Review of Postbox after 5 years

5.0 5 years ago

Comments: Postbox is our go-to email client for our OSX platform. Filters, rules, folders, quick commands - excellent choices to help speed along message handling. Also excellent capabilities with encryption and signatures. We haven't found a better product - if we had, we'd be using it.

Pros:

Very flexible and very capable, lots of options to speed through messages with good formatting choices including message content, message handling. Excellent multi-account handling.

Cons:

Does not handle very very large IMAP accounts too well, especially if gmail / gsuite based.
