Best Free Email Software


With so many clients now in the cloud, rather than on the desktop, email clients have certainly taken a turn over the past few years. So, to differentiate themselves, the desktop clients have become more advanced and offer more and more features to keep customers interested.

For most users finding a good email client can mean the difference between getting on with your work or hitting your head against a desk in frustration.

Here's a list of the best email clients reviewed and compiled to save you from heart/headache. For ease of use I've split the review into two different categories, desktop and web-based.

Mozilla ThunderbirdMozilla Thunderbird is a free, open source POP and IMAP email client developed by, the same folks who brought you Firefox. Feature-wise it sits somewhere between Outlook Express and Outlook, which means that it offers an upgrade to Express users and a downgrade to those who use the more advanced PIM features of Outlook.  Additional features can be added through free extensions. Notable among these is Webmail, an extension that allows POP3 access to webmail services operated by Yahoo, Hotmail, Lycos, MailDotCom, Gmail and Libero. Thunderbird email files can be indexed by the Google, Yahoo! and Copernic desktop search programs.

Outlook Express users should seriously consider switching. You’ll be rewarded with a more advanced product with these features:

  • built-in spam filtering and RSS reader
  • message color coding
  • fast email search
  • anti-phishing measures
  • spell check as you type
  • inbox filters
  • Kerberos authentication
  • automatic updates
  • the ability to view your mail in conversational threads.

On top of that, the product is more secure than Outlook Express and, unlike the latter, is still being actively developed. Switching is made easier by the fact that Thunderbird looks and works similar to Outlook Express. Tools within Thunderbird also allow you to easily import your Outlook Express account settings and stored email. If you need assistance, there is an excellent guide from Mozilla available for download in the Quick Selection Guide section below.


OperaAnother good option, that many people are not aware of, comes from the same source as Opera browser. The folks at Opera call it their M2 Mail Client. Although there is no calendar in this program as in Outlook (it wasn't meant to compete with Outlook anyway), it is still quite powerful. This email client is a combined email database, news reader, mailing list organizer and RSS news feed reader, and it supports both POP3 and IMAP protocols. My experience with it was quite pleasant. It was easy to set up, very intuitive to use, and it easily found any contact I had ever had email correspondence with. Overall, it's a very nice product.



FoxmailDespite the name Foxmail, it is not related to Firefox, but comes out of China. It's an impressive product with features that match or exceed Thunderbird's, and it's also very easy to use. My only real beef is the quality of the help files. Yes, they have been translated to English, but rather poorly; so poorly that they are actually quite amusing. With version 6.5 Beta 3 Foxmail now supports the IMAP protocol, which is a big deal for some. If you are savvy enough to figure out the program yourself, Foxmail is worthy of consideration.  It's a top product with eight million users world-wide, and it's a real alternative to Thunderbird. If you need help there's a link in the Quick Selection Guide section.


Incredimail is an email client currently in version 2.0 that supports both IMAP, POP3 and Webmail accounts. The basic version is free to download and use, however additional features like animations, themes and junk filters require you to upgrade to the premium service so that is something to watch out for.

The user interface is well polished with basic animations that pop up when you receive a new email or if you delete one. This is a nice touch but can get in the way, it can however be disabled.

Incredimail supports Webmail accounts for GMail, Yahoo, AOL and Windows Live Hotmail.

The initial setup was fairly painless, the software detected the settings I had for Outlook although it got one of the port numbers wrong, but that was an easy fix in the settings. It also downloaded all the existing emails in my inbox and transferred them.

However, you are required to select the tool-bar integration and have Incredimail as your default search engine before you can proceed.

As a basic email client that can handle all of the main accounts, this is a very easy to set up and capable program, but it's limited by the need to upgrade for other main features.


eM Client is a popular client for Windows (XP - 7) that supports all popular webmails as well as POP3 and IMAP. Upon downloading you get a 30 day free trial, which grants you all the features, but the free license constricts you to only 2 email addresses per user.

The user interface for eM Client is certainly very swish (I haven't said that in a while...), and certainly looks and feels premium when using. There are no ads, or gimmicks, just a clean interface, not dissimilar to Outlook 2003. Initial setup is very easy, allowing you to import your accounts and settings from the clients already installed on your computer; and even manual setup was very easy, a nice interface to guide you through.

eM Client is certainly one of the better looking clients available for Windows however, the free version is held back by the account restriction to only two email addresses.


GmailLet's get this one done first! Gmail, arguably the most popular webmail client at the moment, integrating deeply into the Google ecosystem and offering more features than it ever has before. On that note, features wise, it has a lot that you would expect such as:

  • works with both POP and IMAP
  • arrange emails into folders by adding 'Labels'
  • filters
  • contacts and tasks can be added and amended.

You'll find you'll get a lot more out of Gmail if you use other Google products. For example, if you use Google+ (which, realistically, you don't, but hypothetically...) you can chat right in the Gmail window, you can also view your circles on the right hand sidebar. Another great feature is Google Labs which is a series of add-ons that you can use to customise your Gmail; it's a very nice feature for more advanced users and it's great to see this amount of customization in a webmail client. 

Although Gmail is free, there are ads displayed at the top of the list of emails which is fairly unobtrusive, but can make things look a bit cluttered and at first for me when I tested it, a little confusing as I wasn't expecting it.

You get 10GB of space for free, but if you need more (again, realistically, you won't), Google offer monthly payment plans to get you more space, which can go up to 16TB.

Gmail is at its peak, but there are downsides, the adverts while discrete can annoy some users and the Google+ integration can seem annoying if you don't use it; however, all that put aside, it's certainly a stylistic, elegant email client and offers a great number of features.


OutlookOutlook (the new Hotmail), Microsoft's really gone all out with it's Modern UI! It's taking all their products by storm, and Hotmail's next on the list. The new user interface of Outlook is very simple, with the layout of Hotmail remaining largely intact, but with better visuals that newcomers should find more appealing. Setup is fairly simple (or if you have a Microsoft account already, non-existent), like Gmail it provides options to get your old emails forwarded to one email address or access them directly through POP3 or IMAP support.

Some nice features include: being able to delete all emails by a certain sender, or even choosing how many emails from that sender to keep before automatically deleting old ones; automated replies for when you're away from your computer; as well as filters and folder; and all that jazz. Also, being able to import up to 4 POP3 accounts should keep most users satisfied. The built-in contact list 'People' is very modern, as is the calendar, but both put style over functionality as it can sometimes be difficult to access the advanced options.

On the down side, if you're not a fan of the UI, it is everywhere and while for the time being you can swap back to Hotmail view, I wouldn't expect that to stick around.

No love for nPOPuk? Might not replace a full-featured e-mail client but a useful supplementary for quick checks and at least some automated mail management. Small, quick, portable. Recent versions have useful improvements like the preview pane, and better filters, nearly good enough now to replace Magic Mail Monitor (and being in the INI file, they're more easily edited). Also filter boxes, so filters can automatically copy or move mail to permanent folders, etc. webmail is one to consider.

the webmail (not pc client program) in myopera was pretty good. It was part of the whole myopera community. It went "out of business" as of 3/1/2014. Ie tomorrow ;) However the developers created; It is also a whole community. When i load their pages and watch the websites go buy in the lower left of firefox, i do not see many other sites go by besides In fact i just double checked now, and the ONLY website i saw go by was Their servers are located in Iceland for, among other things, their commitment to free speech. It appears on first glance very open source mindset friendly.

Their vivaldi mail is a hosted roundcube program. I have found roundcube only meh. But free as in freedom is a big plus. Altho this is just a first impression, i dont really "know" the community.

The tech world is changing. There use to be "free as in beer" and "free as in freedom". Now there's also "free as in build a profile on you and sell it for ad targeting".

Some other notes:

vivaldi does not (currently) require a cell phone to register. They require an alternate email which they use for "forgot password" retrieval. gmail and yahoo both require a cell phone these days. is another "very free" email. It is very Ad HEAVY. From a couple hours surfing, it has mixed reviews. Gmx has the advantage that it does not (currently) require a cell phone nor even an alternate email address to register. Their "forgot password" retrieval is based on a security question.

There is a mistake in the DreamMail section. It does not support IMAP. It was planned / promised for version 5 (10 or so years ago was the First promise).

Sadly Foxmail does not support S/MIME. I also have problems contacting the developer (they seem to ignore my emails).

Maybe Zimbra Desktop is also a look worth: . I haven't tested it though, as I am using em Client (slow start up).

seamonkey is an excellent product that combines a browser with a free mail progam (like the older opera used too).

opera mail is no longer a part of the browser and can be had separately.

M2 (Opera) is also the best choice for me. Although I found that the integration within the browser was great (I am sad that they do not give the option to keep it inside Opera Browser). The new version has a lack of customisation features that were available when it was part of the browser.
But it is extremely fast and perfect for me.

Ok, is there anything that can handle all the correspondence with one person, incoming and outgoing, under the same folder?
I have Evolution. It has filters for incoming mail, but outgoing ignores it. Why?

Anybody looking for a free, clean, simple and fast e-mail client would find Postbox Express as the right candidate. It is a 'toned-down' version of the well known paid software Postbox. I'm a very satisfied user and other friends might care to look at it.

I've used Eudora for as long as I can remember. For two pull all my email addresses together and the mail they generate. But I loved being able to pull up the folders from Eudora into notepad or Word. Loved it. Do any of the email clients out there do this? Or are they only able to be read in the program the email rolled into?

Hey guys,

It's me again, this section along with many other unfortunately is very outdated, both on standalone client and web mail services, i think it is obvious for most that the main 2 web service for email are Gmail and Hotmail, let's add another one that is in no way falling behind the great two - - great functionality, check this one out.

Personally i think in today's terms, when everything is "cloud" based there is no real need in standalone client such as Thunderbird or others, Gmail, Hotmail and GMX give you all you need (including online drive to store your files on - Gdrive and Skydrive + free online office to edit and view your documents - google docs and Web Office), BUT if you still want one, i'd recommend the same one i recommended here few years ago and is by far better then all the rest reviewed here, eM client. Yes only eM client, why is DreamMail still here? It was dropped long ago and no longer supported, or incredimail? Is this a joke? There is almost nothing good about incredimail, except cute mail themes and email notifiers, but nobody need these things anymore.

There are plenty of email clients for everyone to choose from: EmailTray - nice, Inky - liked it too, Foxmail - very light and simple, yet no support at all and a very poor English translation, Thunderbird - not bad, for Mozilla fans, basically all of them offer more or less same functionality.

Still, the only one you will ever need is eM client, great customer support, integration with Skype, Facebook, iCloud contacts, Hangouts (ex gtalk), it has everything you need in a great email client: Contacts, Calendar, Tasks, very fast search, Instant messaging, automatic archiving and advanced backup options, Password protection, offline work, customization, you can view your email practically in any way you wish, basically i consider eM client as an improved Outlook.

Definitely worth checking our,

The main reasons I use an email client is to integrate the many email accounts I have, to integrate with other applications on my PC, and to allow me to work with email even when offline. I use cloud data storage to synchronize files across multiple PCs.
@CyberAlex1986. This review currently has no editor so the content will not change until someone volunteers to take it over. Why not offer to do this yourself as you appear to have done most of the ground work for an update already? MC - Site Manager.

Foxmail quick selection should probably be updated.

There seems to be a newer version than the one listed in the quick selection list


evidently there is now a portable version.

Thank you. I have updated our information. :-) I was not able to verify a seperate portable version. This release can be run in a portable environment.

Please note that DreamMail is no longer being supported or developed.

Thank you. Noted.

Eudora 7.1 is the last full-featured, "professional" version (only fast-global-search function dropped but from all versions), and is now free for the taking. Qualcom hosted a community support forum for years, and that community is still somewhat active but scattered a bit now.

Maybe Eudora 7.1 should be evaluated and listed here. Even though development stopped in 2006 (or 2007 ?), it doesn't seem that any other email client has come close to the same utility. That is a striking anomaly, but maybe other communication apps are where developers now spend their efforts. Thanks to Qualcom for continuing to distribute the program. Too bad the code could not be unlocked for the the open source development project. Eudora OSE (aka version 8._) failed and should not be confused with the "professional" version.

The reason I am looking at email client reviews is that I was a totally happy Eudora user but I started using Thunderbird when Qualcomm stopped doing upgrades. I soon found Thunderbird inadequate so I switched to Pegasus - same story.
Like shawnz I think that Eudora was (is?) the best email client around.
I think that I will go back to Eudora, join the support forum and get on with the rest of my life - hopefully without any more email hassles.
If Qualcomm should decide to put some money in to supporting Eudora I would be happy to toss in my annual subscription to assist.

I am seriously looking for email software in which I can compose like a word processor (e.g., MS Word) with choice of font and font size and other features. Thunderbird is like buying a dress shirt with Small, Medium, and Large, as opposed to numerical neck size and sleeve length. Outlook Express was great in that regard, but it stopped recognizing my password and could not be recovered, so I've enjoyed Thunderbird for several years, but am frustrated by its arbitrary, random jumbling of fonts. After I set a default font, it keeps changing size and/or font right in the middle of a message. After I finally get a uniform format, it still changes after I hit SEND. I'm a good writer, but my messages look like I'm a computer moron.

I seem to remember a button in MS Word to send a doc file. It was years back, and I liked the idea at the time, but I don't remember using it. Regardless, Microsoft should probably not be allowed to observe you connecting out to 3rd party servers and contacts. The function should hand off to the email client for that.

As for Foxmail the note regarding the portable version needs to be updated, as a portable version is available on Foxmail website.

Having twice in the last two month had the mail in my inbox just completely disappear, I find the endorsement of Mozilla Thunderbird as the best choice quite questionable. A check on the web indicates this is quite a common problem.

Coupled with Mozilla's recent announcement of the cessation of further development of Thunderbird has persuaded me that it's time to move on. So I'm open to suggestions on a reliable free or fee PC based email client. (Which is why I came to this site in the first place).

For those persisting with Thunderbird, I suggest they move the contents of their inbox to local folders on a frequent basis. But with caution.

In fact it was in the process of doing this that I lost my inbox contents. I had sorted just over 100 emails into sender order and had transferred a group to a topic specific local folder when zap!, the rest of the inbox disappeared.

Caveat emptor applies even with freebies!

I personally have used Thunderbird since, oh about v4, so in other word..QUITE a while.
And NEVER have I seen email just "disappear" from the inbox.
This HAD to be user error.PERIOD.
Possibly a setting that is wrong or something. But it simply does NOT just vanish on its own.
As stated, from about v4 to current v24.6. NEVER EVER.
Also by now it is also apparent that Thunderbird is a "community supported" project, and has NOT vanished either.
I use the inboxes on 3 accounts no problem, I also archive and use local folders as well. Again, NO PROBLEMS.

As next Opera release is gonna be based on Chromium, M2 will be most probably released as stand-alone app.
RC are already available.

I also find M2 one of the best (if not the best) email client around.

Another client that worth a mention imho is Claws Email:

[Moderator's note: Links to direct downloads of files removed. Not allowed as per site rules.]

Regarding using Hotmail/, I believe all of your data will be deleted if you don't use your account every six or twelve months (or something like that). I've personally experienced this, and it's a pity when you lose years worth of data.

As far as I understand, Google doesn't have this restriction.

Thunderbird provides no privacy for your mailboxes. Anyone with access to your computer can open Thunderbird and read all your emails. There is an add on to password your Thunderbird profile, but it is easily circumvented.

My personal preference is back with Opera Mail. I tried Opera in the latest version this month, and I have to say I am impressed; it offers fast / seamless IMAP and is better than anything I have tried past or present.

Some background... I have tried all of the above, and some not listed here (Zimbra amongst others) - and have (unfortunately) always ended up using the web based offerings of Google and Microsoft and for a long period have done so; but recently they "improved" their offerings to be so "feature rich" that they are too slow to load and use, and now have strange quirks in their UI that cause many a frustration.

And then we get to Thunderbird; for me I find it surprising that this is at the top of any review list - large footprint, slow / cumbersome to use / setup and frequently unreliable. An example, I contracted at a business in recent years where it was used as the primary for the email system; where it did a fantastic job of frequent corruption of its own email database and was almost impossible to restore. Following many wasted hours and lost emails, Thunderbird was dropped and the Linux equivalent of Outlook (Evolution) put in place with much improved reliability.

I have personally tried and re-tried Thunderbird on occasion over the last 4 or 5 years; it keeps coming on top of reviews so I keep hoping it has made the improvements that make it worthy of such a spot; but the end result for me is always the same - I un-install it.

I would advise, to try the following:
- Opera Mail (latest version is very fast, small, reliable and seamlessly integrates with the what is likely the fastest Windows browser available)
- Dream Mail (also very fast, small and reliable; but it doesn't have IMAP)
- Evolution (has everything including Exchange support - but is only a Linux client; its worth running a Linux VM just to use it and get rid of Outlook - it really is very good)

In my experience, too many of the clients are unreliable / slow or are trying to be "clever" when all most users really want is simple, reliable and fast email.

Again, see my post above. I have used Thunderbird from around v4 to current v24.6.
I have emails stored in there going back to about 2003.
The only reason I lost email PRIOR to 2003 was I was using MS Outlook 2000 and it decided one day to upchuck and die and POOF gone.
Never has it been too heavy on resources, maybe a little slow, but when you consider the profile with all that email archived is approaching something like 2/3 to 3/4 of a GIG, well, it explains it.
As for Opera Mail..YUK!
Tried it and never went back. Did NOT appreciate that it organizes your mail how it sees fit (oh yeah you can "tag" and all that) but it does NOT store them in a distinct layout on the drive (aka FOLDERS).

I too have used Thunderbird like for ever on Windows and Linux. I use mostly Linux and as I have emails coming in all the time the Firetray extension that let's me see the numerical count of new mails is a great bonus. Thunderbird collects from my Gmail, GMX and webmail accounts, all of which have some sort of tag system or message filter applied. There was one Windows version some time back that would suddenly stop collecting mails at the preset interval automatically, but apart from that I've never had a problem with either platform. MC - Site Manager.
Evolution is available for Windows but I never found it stable enough to use. Even on Linux I had some severe issues such as a random desire to re-download mail that was already in one of my inboxes, and it would never auto connect to GMX if I had a torrent running. Thunderbird on the other hand has been fine on all my systems and I use it for both Linux and Windows. As with all data I keep it backed up and on the odd occasion when something does go astray (sometimes after an upgrade) I can always restore. eM Client is a better Evolution alternative for Windows (but limited accounts in free version) although no doubt some will complain that it's heavy. MC - Site Manager.
