Thunderbird

Top Pro

Stable

Design and the app has not changed significantly since its beginning, making its learning curve negligent. See More

Top Con

Ugly interface

Not very customizable in terms of colors for the layout to suit your own taste and style. See More

Melisa Juric's Experience

The email client I ever used for Windows OS See More

Specs

Platforms: Windows, macOS, Linux

Top Pro

Free and open-source

Thunderbird is completely free to use and it's code is completely open-source which means anyone can look at the code or use it for other projects. See More

Top Con

Time consuming configuration

If you have to manage many accounts, consider to waste a lot of time to configure them. If something goes wrong extra hours are required. Editing the .js file is also a tough task. Missing a lot of natural features. See More

JollyGenann's Experience

Always had great experiences with T-Bird. See More

Top Pro

Easy to setup

You only need to add the account and email servers. See More

Top Con

The search function is terrible

Jean Roses's Experience

I'm able to have several email accounts, and I like its simplicity. However, a big con is that I have never successfully been able to import emails or addresses when needing to move them to a new computer. The directions are complicated, though I do follow them exactly, but it just doesn't work for me, and I've lost a ton of addresses/emails. also, when an email is flagged as possibly malicious, the only option I can choose is "ignore warning"; why not add "not malicious" or "not spam", so I don't have to designate it twice? See More

Top Pro

Very reliable

Version after version, Mozilla Thunderbird works as expected. See More

Top Con

Very slow

Starting with a large number of accounts and mails can be slow. See More

InterestingArke's Experience

Even after all this time it's still one of the few if not the only email client that you can redirect and or filter forward!! See More

Top Pro

Large assortment of plugins

Thunderbird offers a huge amount of extensions to expand the usability and options of the client. See More

Top Con

No sync with Google Calendar

Not in version 78. Sync's great with the Provider for Gmail extension (add-on). See More

programan's Experience

What I understand about this e-mail client is that it supports an unlimited number of email accounts, then it's expandable via plugins and easy to set up See More

Top Pro

Available on Linux, macOS and Windows

That way you can keep on using the same application (and data records!) when switching the operation system. See More

Top Con

With version 60 a lot of add-ons became incompatible

And thus reducing the excellent e-mail client to an average one. See More

WiseChalchiuhtotolin's Experience

Have used it for years and though it has an outdated interface, it works very well, even with the large numbers of mails that I have! See More

Top Pro

Send large files

Thunderbird is the easiest way to email large files. Get pCloud's plugin for Thunderbird and the next time you drag & drop a file to your email, it will convert it to a Download link. See More

Top Con

No conditional formatting

Chris Qie's Experience

••••••g •••t , 90% website RSS can't be used with this software. See More

Top Pro

Lightning Calendar and Address Book integration

Support is limited to predetermined solutions

kadybee's Experience

Highly customizable with add-ons. See More

Top Pro

More options and extended settings than most power users could dream of. Get it working how YOU want. See More

Top Con

CoherentIhy's Experience

The best by far, any other free mail client falls short compared to it See More

Top Pro

Portable bundle available

At least for Windows. See More

Top Con

No Sync with Google Contacts

CoherentActaeus's Experience

Very easy installation, captured Calendar and Contact's feature from Gmail & Yahoo mail server's. Email list font size change challenging to find, but not impossible with online forum's help. One of the Greatest opensource free email apps available. See More

Top Pro

Good filtering system

Flexible filtering system with the ability to set flags and read/unread as well as sort/assign to new mail directories. Numerous plugins to assist in the filtering, as well. See More

Top Con

Subject lines can (temporarily) disappear from the list

This is sporadic behavior. See More

Aurelius's Experience

I've been using Thunderbird for almost 5 years now, and there's a reason why -- it's incredibly stable, fast and easy to use. The Add-On system is great, supporting EnigMail for encrypted email which is a huge plus. It is very easy to setup, especially if you use one of the big free email services, but even on my personal email server it detects the settings automatically. While I don't use the Calendar feature much, it seems very full-featured and easy to use as well. Also, Thunderbird is cross-platform, so when I switch back and forth between Linux and Windows the interface remains the same, a huge plus. There simply is no other choice for me! See More

Top Pro

There is a plug-in (not free) that allows full Exchange integration

This addon can be found on the Mozilla Extensions for Thunderbird. See More

Top Con

Importing/exporting emails, addresses is complicated

CalmNinigi's Experience

Mozilla as a whole has gone down hill lately with their add-on support issues. This means that although this would be a very capable and complete client, it constantly takes those features away with major (usually on a minor release) updates. Lightening has been less reliable as of late and the calendar system no longer stays on the current day with the latest update. See More

ProductiveArohirohi's Experience

DedicatedAphroditus's Experience

Used to be my #1 client, but now that I have multiple mail accounts and very full inboxes it has become insanely slow. My computer has 16 cores and it only seems to make use of 1. Too bad, otherwise it's a really nice and stable piece of software. See More

dotmavriq's Experience

It's still the best E-mail client for Windows.. I almost want to add unfortunately because it surprises me that no one bothers with developing an e-mail client that does what Thunderbird does only better.. because I do feel that there is room for improvement. See More

Top Con

Can't use without creating a Mailspring ID

There is no need to create a third party ID for an email client. What if the Mailspring closes in the future - can't install a previously downloaded Mailspring software any more to continue using it or access your stored emails? See More

Miep's Experience

Sometimes one has to close an account and open a new one. E.g. for safety reasons. Mailbird does not allow for moving mails from old accounts to new accounts. Not even the PRO version. See More

Top Pro

Unified Inbox

This allows you to funnel all emails from all accounts into one unified folder, so you don't have to move between different accounts. See More

Top Con

Mailbird does not support moving emails between accounts

It's a disaster when you need to transfer all mails into a new account but you can't. See More

SuccessfulCoventina's Experience

It works beautifully and is simple to use. It now incorporates all your contacts and even sites such as dropbox. A truly excellent and class leading email client. See More

Specs

Top Pro

Excellent UI/UX

The UI looks simple but is customizable. UX is also simple and easy to use. See More

Top Con

No updates

Program seems to be 'end of life' as since December 2021 (it's now almost July 2022) no updates were issued :-( See More

Miep's Experience

There's no way to move emails between accounts (imagine you have to close an account for whatever security reason, and you have 2000 emails to protect ..... ). Importing addresses is limited and complicated. See More

Top Pro

Undo send

Top Con

Search is slow

Searching within all your mail takes quite some time. See More

Sanjay Ramnathan's Experience

Mailbird can be best described as a skeletal email client with an IMAP email account actually having to do simple functions in the background. See More

Top Pro

Free and paid versions

Users who only need to use the basic features of the app have a free version available, though it does limit to only 1 account. There is a paid Mailbird Pro version that does extend functionality and allows for unlimited accounts but it does cost $1.00 a month or $45.00 as a one time fee. See More

Top Con

Not possible to rename the accounts

You always see a mail address as the account name, it's not possible to change that. See More

ImpartialCeres's Experience

By far the easiest, simplest and cleanest UI. Very quick to navigate, great features without being overwhelming. I like to have a clean and uncluttered mail client the same way I like to have a clean desk. Staying focused and keeping organized is just that much easier. Mailbird does this better than anyone else. It's a damn shame that Protonmail don't give official support for using their servers with Mailbird as I've had to stop using it because the Protonmail bridge doesn't communicate with it as it should. Every day I lament the loss of Mailbird :( See More

Top Pro

Apps that extend functionality

Mailbird 2.0 supports separate apps that can extend the programs functionality such as Sunrise Calendar, which allows one to add multiple calendars in one view or Evernote which allows for easy not taking and sharing. See More

Top Con

No mail sorting possible

It's not possible to sort the mail list, so you will always see the mail 'date sorted'. See More

Toker's Experience

Mailbird is the best email application for windows period. Most importantly they are constantly developing, and improving the product. They see the reviews and criticisms and adjust the product accordingly. One example is the fact that they have recently added the ability to filter emails (a major criticism about the program for a long time) It functions nearly flawlessly. The only major con that I have experienced is that it takes longer to receive emails than other clients. It does require some patience when it comes to emails that are supposed to be instant like when you are resetting a password. Still overall, this a windows app that functions with the grace of a mac product. If I could put mailbird on my ipad I would. Mailbird should be ranked number 1 when it comes to windows. See More

My mailer since 28 years - mail handling, automatic sorting, templates etc. extremely convenient for work with multiple email accounts (IMAP and POP) and diverse projects, and managing RRS feeds - in my view better than current Outlook. Absolutely stable, security and privacy assured. Adressbook difficult to synchronise with Outlook etc. No calendar, calendar functions for google/outlook not supported = you can't receive invites.

Smart lookup is a feature where the Bing search engine is bundled in the app to allow users to automatically search for relevant websites, information and images based on the word highlighted by users, without need to open external browsers. The results will be shown on the right pane of the window. See More

Postbox

Top Pro

Clear interface

Top Con

No support forum

Support for paid product has no online forums. See More

BrilliantHeracles's Experience

Version 6 of Postbox for Windows is a pleasure to use, but as with Mac OS X, version 7 of Postbox for Windows spelt disaster for those of us who do not have perfect arm control due to the needless introduction of very narrow scroll bars with no up / down arrows to click on with a mouse or, in my case, a mouse alternative. As an e-mail user since the advent of Pegasus Mail for MS DOS 5.2, I worry when a company tell me that we are #allinthistogether (the slogan on their website) but then tell me that they dropped the conventional scroll bars "as it's a competitive market and they have to be innovative". I never thought that a decline in accessibility / user friendliness (which share common ground) would be seen as "innovative", but there you go. What a crazy world! Postbox Inc owner, Sherman Dickman has not responded to any of my messages via LinkedIn or Twitter and his staff see fit to tell me to use Outlook (no thanks!), or other clients as they no longer support version 6. So, I hear you ask, why does this lady still use Postbox 6? Well.. Its a great mail client, great U I, and smart folder filtering that sadly, I can't find in any other mail client. Given that personally, and with work, I have eight mail accounts, this is a pretty important issue, and short of writing actual IF Statements, Postbox's choice of filtering criteria is as extensive as it can get. I would love to use version 7, but Postbox Inc only make this possible if you have a steady upper body control. In 2020, this is crazy. I have asked Microsoft to make it impossible for developers to implement this type of scroll bar. Fingers crossed (if I could!!!) Sarah in Cornwall, England 2nd June 2020: Postscript: since writing this review of Postbox on 31st May 2020, my account on the Postbox Inc website has been suspended.... Does this mean that Sherman Dickman and his staff are of the opinion that disabled people should be "spending but not heard"??? Deeply concerning... Come on Mr Dickman, its the year 2020 now...!

Forgotten attachment reminders by default

Reminding the user that they forgot to attach the file if they mentioned one in the body of the email is one of the most useful features of any email client and so many don't include this.

eM Client

Top Con

Extremely slow opening emails

PerfectHypate's Experience

Switched to eM Client, when I realized Outlook sends pdf files as "Winmail.dat", which can totally disable your ability to send faxes from your email. Outlook is too buggy. --Spent most of my time doing research in forums, for how to solve problems, and got fed up with it. eM Client has a modern, simple, clean, adjustable UI, that now offers multiple themes. Under the hood, it has more powerful options. It does everything Outlook did (at least as far as I needed). Most of the objections to eM Client on here, were probably written before eM version 7, which corrects many of those issues. Also, they are consistently developing eM Client. See More

Innominatus's Experience

I was looking for an alternative of Windows mail and Gmail to combine both gmail/hotmail account. I was with Thunderbird first. But interface is a bit ugly and I don't agree with Mozilla political view no more. So I switch to eMclient and it's far better.

MailBird

Top Pro

Free and paid version

Users who only need to use the basic features of the app have a free version available, though it does limit to only 3 sync'd accounts. There is a paid version that does extend functionality and allows for unlimited account but it does cost $1.00 a month or $45.00 as a one time fee. See More

Top Con

Collects user data

Mailbird does collect some user data such as user email addresses, names and client use. So for those that are security minded the use collection of this information may not be wanted and can not be avoided. See More

Jane Lau's Experience

good See More

Top Pro

You can have multiple accounts

In Pro version, you can create an unlimited number of accounts. See More

Top Con

Feels more like a browser than an email client

A browser-based app from the windows store, for example, Gmail, does almost everything this client does for free. The calendars in MailBird don't sync with your email addresses. You have to manually change them, whenever you want to switch between calendars. Every time you perform a function, it's like it's downloading a browser view of your accounts for display, rather than performing an internal function. Totally has the look and feel of using a browser-based email client. See More

Top Con

Price jacks up between your first and second visits to the site

The first visit to the site offers one price, but a revisit later on reveals a much higher rate. See More

Top Con

Very slow on Windows 7

Maybe this is just on my system. I haven't tried it on a new system but it is very slow. See More

Top Con

Drag & drop is impossible

Drag & dropping folders and emails between accounts are not possible. See More

Top Con

Poor import/export of contacts

You can only import your contacts data via CSV, which isn't the most popular choice. Much more convenient ways to do so exist. Even the older Windows Life Mail program is more flexible when it comes to contacts and offers such features as duplicate checks. See More

AdaptableOxomoco's Experience

Very good! Easy to work with and not using the annoying tree pane view. Everything is centered around a treeview which you can drag, drop and move to any location. It is actually an organizer but with a nice multi platform email client as well. The automatic in and outbox handling as well as the way you can drag, move, copy, paste in and out boxes as well as emails and attachments is something not found in other email clients. This way I can group emails from different email addresses into a single email folder. I can even from the organizer docs and notes, hyperlink to contacts, their emails and attachments! See More

Specs

Platforms:macOs, Linux, Windows

Top Pro

Packed full of features and still an email client

Treeview serves well as an access point to emails and all other things inside FileOne. Allows attachments directly from the treeview too. See More

Hans Tijveleijn's Experience

Personally I've always preferred light email clients, like the late Microsofts Outlook Express. Of course in collaboration with an IMAP email server so I can always access my important messages through remote channels like webmail or an app. But when it comes to integrating all the information I might want to share with my network in an organised and protected environment I discovered FileOne delivers the best opportunities I'm known with. As a self-employed IT professional I care for keeping all information items of interest in a documentary system that is structured just the way that comes to my mind. Whether it involves correspondence, articles, manuals, reports, examples, links, quotations or invoices, either by text, sound or images I can relate it however I want. As I can collect it however I want, by email, browser or upload form my local computer. True, there are many kinds of business solutions that offer the same abilities but they all depend on a more heavy weight, not to mention costly, platform. And the services offered by cloud computing service providers I reject firmly for why would I leave my important data, both personal and businesslike, with parties of which I never have the certainty that it will not be accessed without my knowledge. But with the properties of this integrated email client I can keep my "mental belongings" as secure and personal as my LAN is. FileOne simply runs on my Windows laptop with its database file stored on my NAS, replicated easily for portable use. And with these features it's the most convenient data centre I know of. See More

Top Pro

Simple backup possibility of personal data without storage in the cloud

Because all FileOne's content is contained in one file, actually a database, it's easy to maintain copies of it or store it on a mirrored disk. This way you share your information with no one but with whom you choose, through FileOne. See More

Michel de Kraker's Experience

I perform alot of installations at several customers for alot of diffent software products. You can imagine i create alot of documentation etc. on all installs. I find FileOne the best software to do this. If i need some documentation and just search within FileOne with only a few search item. And also the integration with mail is very easy. I really like FileOne! See More

KindheartedWaygl's Experience

We tried several email programs for our office like Outlook, Thunderbird, The Bat, emClient - they all have serious drawbacks, even Outlook, which slows down or even "freezes" if you have a lot of emails and pst files approaches 2GB in size. Transparent end-to-end encryption was also one of the major feature we were looking for - onle EverDesk provided something close to what we wanted to have. One of the great things we discovered later is how easy it is to back up all the data - just one folder has it all. See More

Seamonkey

Top Pro

Not just an e-mail client

Top Con

Permanent CPU usage

Seamonkey permanently uses CPU (quite a few percents on a Intel i7). On a laptop this causes the fan to run (which make noise) and the battery to lasts less time. See More
