I have been using K9 for a long time on Android. No complaints. I guess most Apple users will simply use the default email client, which works well and is probably better integrated and has a better UI than Thunderbird.

On Linux desktop, Thunderbird is still the best all around email/CardDAV/CalDAV client it seems, despite being unreasonably heavy.

  • kvuj 1 day ago

    From what I've heard though, Mail has pretty horrible searching in Apple land. Just for that, it may be worth it to look at alternatives.

    • setopt 1 day ago

      It depends on your provider, unfortunately. If you use their iCloud mail service, search works fine – it appears to have some way to do server-side search for their own email.

      • Gigachad 23 hours ago

        IMAP is a horrifically insufficient protocol. Literally every mail provider just implements their own custom JSON protocol to use with their own proprietary apps. Fastmail created JMAP which was meant to be an open source standard but so far only Fastmail uses it so it's just another provider specific protocol and client.

        • brongondwana 20 hours ago

          I do think 2027 might be the year that JMAP finally gets wider adoption! Between Thunderbird using Stalwart for their hosted product, and the fact that the new agentic tools are very good at writing JMAP integrations, I expect plenty of much better JMAP tooling.

          I'm also close to a much more releasable version of the proxy which was first written back in 2014: https://github.com/jmapio/jmap-perl/ -- which can wrap existing IMAP/CalDAV/CardDAV/Submission infrastructure so you can access it via JMAP.

        I use icloud and this does not match my experience ... apple mail search has been insufficient on ios and macos for 15 years or more at this point ...

        • tssva 21 hours ago

          I use icloud also and concur. Search in Apple Mail is poor.

        • setopt 10 hours ago

          Not sure what the difference is then. I use iCloud Mail and didn’t have problems with search on iOS or MacOS, I did however have plenty of issues with search when syncing my work Outlook email via Mail.app, so I assumed there was something special about iCloud (similarly to how Mail.app offers push email only for iCloud and FastMail). I’ve imported decades of email into my account so it’s not about a small email volume either.

    Do most Apple users not just use the Gmail apps and web app? I haven't set up an email client in 20 years

    • setopt 1 day ago

      I don’t know what most do, but I certainly prefer the default Mail.app over the vendor-specific mail apps.

      If you’re already using one of the major providers (GMail, Outlook365, etc.), there isn’t much to configure; you go to Mail Accounts, click your provider like Google or Microsoft, and login on their website to authenticate.

      • steezeburger 23 hours ago

        Oh for sure. Huge assumption on my part. I just feel like 90% of people I work and interact with have a gmail account, and the last 5 companies I've worked at used gmail. I think the last time I setup Apple Mail was for my Grandma so she could see her old Cox account emails and Gmail emails in the same app.

      • wycy 23 hours ago

        The default Mail app still doesn’t support push Gmail, does it? That’s the only thing keeping me from using it. I otherwise strongly prefer Mail.app.

    • siskiyou 20 hours ago

      Absolutely not. I see a huge number of iPhone users for in person tech support and most use the Apple Mail app. These are ordinary people who know nothing about pocket computers.

        Thanks for your data for sure. I used to work in customer facing hardware support, but only have my friends and coworkers to go off of now.

      • DrewADesign 19 hours ago

        Even many people familiar with pocket computers use the iOS Mail client. I was an email user over a decade before Gmail existed, and I used mutt for most of those years. I happily use the iOS email client because of the OS integration, clean UI, well-designed interactions, and decent support for wherever my email happens to live that year. I think mostly it’s because I’ve dicked around with computers enough in my life, and I’ve no interest in doing so with my phone, too.

    • stackghost 17 hours ago

      I recently switched from android back to iOS and tried to use mail.app for everything, as I rather like it.

      Unfortunately it doesn’t sync properly with Gmail. I am in the process of de-googling my life so that’s okay with me. I use mail.app with my fastmail account and it’s perfect.

      > Do most Apple users not just use the Gmail apps and web app?

      People here are discussing email apps, not Gmail apps.

      Gmail apps only work with 1 provider (gmail), while email apps works with all email providers.

      • Melatonic 4 hours ago

        You can add other emails to the Gmail app actually

      • steezeburger 1 hour ago

        I think you can actually add other providers to Gmail, but my comment was about how most people I know only use Gmail, and they have no need to configure their os-of-choice's mail app. I guess that was kind of implied. Sorry if I was ambiguous!

        I might be an anomaly. I've ran iPhones before and have an iCloud email address presumably, but have only ever used the Gmail app for email on my iOS devices. And on my other machines I just use the web app. This seems to be the same for most people I've worked with in the last 5 years or so. Obviously it's super anecdotal and just from observation.

  • aucisson_masque 23 hours ago

    K9 and Thunderbird on Android suck. The ui is clunky but worst of all, the search is bad. Very bad.

    If you don’t do anything special, that will be enough but for everyone else that won’t do it.

    If I type ‘repor’ in Apple mail, It will show me all report before I even type enter. And if there is too much, I will then add ‘2026’ for instance.

    On k9, first you got to type the entire word because it won’t progressively search as you type, but then you press enter and see hundreds of mail so you want to add 2026 ? Too bad. Got to type report once again followed by 2026. Made a typo mistake ? Got to rewrite it all over again.

    This is just bad.

    And I’m not trying to diminish the work done by Thunderbirds/k9 developer, it’s just that it’s done by unpaid developers and it shows. Things move slowly and just suck at using.

    • Denatonium 23 hours ago

      Isn't a lot of that just the suckiness of the IMAP protocol? Mozilla is pushing to add JMAP support to Thunderbird, and they're planning on using it in their upcoming Thundermail hosted email service.

        I get this, but most email is through Google and Microsoft in NA, at least, neither of which seem to care to support JMAP at all, on fact they are getting locked down more and more.

        • ahartmetz 10 hours ago

          Obviously they want you to use the web interface so they can show you ads and gather more data about you (for ads).

          JMAP support turns out to be a strong signal for the business model of an e-mail provider. IMAP they have to have, JMAP is for those who actually care about supporting local client software.

      • smallerize 20 hours ago

        No, it starts by searching the emails that it has loaded locally first, and then there is a button if you want to search on the server.

          • stackghost 54 minutes ago

            It's quite cluttered UI for sure but it actually works and you actually get notifications when new mails come in, which is more than could be said about k9 the last two times I tried it.

        Not free, but I've been an AquaMail user on Android for years. IMHO there is nothing better out there.

        And for mac OS, there is MailMate (also not free}, which has it's quirks but damn is it good. I gave up on ThunderBird more than ten years ago.

        Email clients demand to have dedicated, paid developers.

    I bounced off of k9 several times. I could never get it to actually work reliably. I would get an email and never get a notification unless I opened the app to manually check. It was like the bad old days of pop3.

    Awful, awful app. Fairemail was much better for a power user.

  • starky 14 hours ago

    Standalone email has really been a frustration when it comes to using Linux. I was happy with Mailspring, but it doesn't really work with my window manager. Thunderbird does way too much and its default search behavior is unacceptably bad. I've tried a few other clients and been extremely unhappy with them for various reasons.

I am almost certain that the only reason (feature) I have Thunderbird desktop installed has no place in this iOS app – an editable FROM field. I am pretty sure of that.

Ah, just saw the coolest thing - an epic subheading:

> Designed for growth

Love it. There's no stopping this app now. Godspeed, Mozila/Thunderbird! Grow is the new word.

  • jaksmit 1 day ago

    what does being able to edit the from field enable you to do?

    • tredre3 1 day ago

      The official explanation is as follows:

          If your e-mail provider supports it, Customize From Address allows you to make a one-off minor alteration to your From address without having to create a new identity in Account Settings. For example, if your From address is John Doe <john@example.com> you may want to change it to John Doe <john+doe@example.com> or John <john@example.com>.
    • fodkodrasz 1 day ago

      My usecase: I have one email account with multiple aliases.

      I added it to iOS mail with the main alias. I registered to my bank using a secondary address, a more "neutral toned", also one I'd expect to be sold to data brokers, and would be willing to abandon easily if started to get too much spam...

      Now the banking app is pretty... ripe for improvement.

      I report a bug in the app, and the way it happens: it throws up an email editor, with debug info attached to a partially pre-filled form mail. However if its sender is not the alias I set up at the bank, it will get rejected, and will have to do lots if identification turns etc...

      Apple mail does not let you set up aliases for an account, I'd need to log in twice to the same account to be able to do this. Also apple mail is a piece of ... modern outlook, to be really rude, so I'm interested in alternatives.

      • ntoskrnl_exe 1 day ago

        In iOS Mail aliases aren't available only with the email providers that you can pick directly on the Add Account screen. But if have an account with someone else and had to add the IMAP/SMTP servers manually, you can add an alias in Account Settings -> Email -> Add Another Email.

        • crossroadsguy 19 hours ago

          If you have my-personal-domain.tld and you have 57 catch-all addresses then to send mail from them you have to add 57 email addresses in there. People know this “feature”. It’s just not what it is being discussed here.

    • drnick1 1 day ago

      Use whatever identity you want. A server that you don't personally own will not normally allow that however. One more reason to self-host email.

    • basilikum 23 hours ago

      If you ask me for a contact email I will tell you something like jaksmit5@basilikum.monster. Editing the FROM field allows me to write an email to you.

      If you ever start sending me spam I can just block that address. Especially helpful with companies.

      You can also use it for sorting emails.

      It's honestly a basic feature of an email client. Even if you don't have your own domain stuff like the plus sign for aliases exists with many providers (or at least with gmail).

    • crossroadsguy 19 hours ago

      You can enter any email address in that field:

      any-user@any-domain.any-tld

      Can be an alias, can be a catch-all email on your domain. Select the right email account (here, email account ≠ email address) with the right pre-configured credentials and that email will be sent, if not it will fail as it should.

      It’s that simple and basic feature. But apparently email clients decided that’s not the right way and they make you pre-add every single bloody email address you ever want to use — this is specially painful for personal domains and catch-all addresses, especially the one-off ones.

    • Tepix 14 hours ago

      If you use subadressing you need it to reply with the same address.

  • domh 1 day ago

    Editable from field is also the only reason I was using it with protonmail. I can't remember if it was a protonmail limitation or a Thunderbird one that meant I had to pre-add any email addresses before I could send any messages from them though.

    Now I'm on fastmail, the from address is an input box that I can put anything into.

    • pluc 23 hours ago

      If by "input box" you mean "drop down list" and by "anything" you mean "any of my account's configured email addresses" then yes.. but FastMail doesn't just let you put anything in the From field - on the web or Android as far as what my subscription shows me.

      • domh 21 hours ago

        It definitely does for me in both web and android. You can setup specific hardcoded aliases for routing purposes but I have a wildcard/catchall and I can put anything in the From when I compose or reply to an email.

        • pluc 21 hours ago

          So by "anything" then you mean "anything under a domain I have a catch-all configured", which makes sense since you've proven you own that.

          • domh 21 hours ago

            Ahh yes. Anything in the user section of the email, not the domain. This was not possible to do on protonmail.

    • basilikum 23 hours ago

      The Thunderbird from field is free text. You get a warning about your server having to support it though.

      • domh 21 hours ago

        Ahh yeah it was probably a protonmail limitation then. Or maybe needing to manually add to both proton and Thunderbird was the friction I remember.

        • basilikum 7 hours ago

          I'd guess it has something to do with Proton Mail's End to End Encryption. They might generate separate keys for each email address or add DNS records for autocrypt.

I was using Thunderbird on Android for years and keep using it on Linux, but it aged rather poorly.

Search is completely useless, it never-ever finds anything. Threads are supported, but their functionality is not configurable so whenever I lazily click on the complete thread (instead of opening it, scrolling down to the last item and clicking on it directly) it opens every message of the thread. Really nice functionality for large threads with 60+ emails!

So I am a bit skeptical why on earth they would increase their coverage when the already supported platforms lack decent UX.

        I don't know what you're talking about. As you said mail hasn't changed that much, I've been using Thunderbird all that time, and except for an improved default theme, they honestly haven't changed much about their core features. In that time I was able to remove several plugins that have been added to core thunderbird, like threaded conversations, google calendar and contact support.

        I think the biggest change has been that people nowadays expect more from a regular email client.

    • secabeen 1 day ago

      GMail search fundamentally has an advantage over a mobile email client as Google can and does maintain dedicated indexes for your email on their servers. While a mobile client could do the same, it's not really something that you want to do on a battery-powered device.

      It would be a great thing for IMAP servers to do, but none of the major open source ones really take on that feature, and Google wants you in their web-client, so searches via IMAP are low-quality at best.

      • xethos 1 day ago

        > While a mobile client could do the same, it's not really something that you want to do on a battery-powered device

        Doesn't this feel like a perfect example of work done at 3AM when plugged in and (importantly) after the battery is fully charged? It won't be perfect, searching for an email in the afternoon that you received in the morning won't be in the index, but I generally don't need search for emails I received so recently anyways

        How long do you imagine it takes to fully index 100 emails? 1000? It's likely under a minute even for 10,000. And it's work that's only done once, they don't need to rebuild the entire index every time a new email is added. They absolutely could (and should if they don't already) index all locally downloaded e-mails. It's bonkers not to do it.

Both also just showed it was an empty email with only a PDF attachment whereas Mail showed what looked like a normal email, including an address that looked like PayPal's.

        I also notice it doesn't handle relayed emails well. I have a bunch of dummy emails and Mail doesn't show me the relayed name, which really hinders my ability to track and combat spam

    It has a few annoyances. For example it doesn't let you see which email address the sender used, or to which of your email addresses it was sent, instead it only shows the person's name. Also it can't attach pictures without having them inline.

When did Thunderbird suddenly become cool again? Suddenly I'm hearing about it in all sorts of contexts.

It's 20+ years old. Is this part of some broader trend relating to mozilla i missed?

Are the core foundations not right in the rejected shared code? Why not fix that instead to get the core right everywhere?

Especially if the goal is "ultimate goal is seamless cross-device experience.", which involves those other apps

Otherwise not much to look at, the screenshots are bog (sub)standard designs a lot of email apps have, no polish despite the claims

"from" and "to" and big gaps is clutter, wasting precious space on small even screens (The logos on the sign in screen are also misaligned, but maybe that's not a polished "essential")

But why? What's the USP here?

Maybe there's a demand for a more feature-rich mail client on iOS, perhaps syncing accounts and filters from the desktop app. But this doesn't seem to be that, at least not at this point.

Apple Mail completely breaks when you have 100.000+ mails in an IMAP account. Even on MacOS it‘s unusable (search, index) while Thundebird works flawlessly.

  • dreamcompiler 18 hours ago

    The Finder on MacOS breaks when it has to deal with more than about 10,000 of anything. The MacOS Finder is chock full of O[n] and perhaps even O[n^2] algorithms that have been there, unfixed, since System 7. Back in 1996, a user with more than 100 files in a folder was unusual, so those algorithms worked fine. Nowadays not so much.

    Proof: Copy 10k files from one hard drive to another with the Finder (not the same drive; you have to prevent COW). Now do the same thing with e.g. cp or rsync on the command line.

    • rmoriz 11 hours ago

      I also noticed a very slow refresh in Finder since like 5 years ago. Apple clearly needs to fix those issues, maybe using some LLM if they can‘t do it by hand anymore.

I don't get why Mozilla's designs are so ugly. It's 2026, everyone has beautiful designs and some browsers (Arc, Dia) are so gorgeous you don't want to work with anything else. And then this not-even-released mail app looks like old Bootstrap web apps. I used to love Mozilla for having some of the most beautiful designs. The era of Forefox OS and Firefox 4 with their beautiful beautiful designs and then they said no; threw out that beautiful dinosaur logo for whatever this ugly pointless one is and now look at their software. My eyes hurt for the amount of design problems in Firefox. Okay you made a bad one, at least start something new correctly.

    I don’t understand people complaining about Firefox UI. It barely exists. There’s a url bar with some buttons in each side. If you use vertical tabs, another bar with tiny icons for each tab.

    There’s so little chrome I can’t find any fault in it. It’s just grey, out of the way, as it should be.

        There is too little in modern "nice" designs... on VS Code for example all the title bar is filled with junk buttons by default, and you have to search hard for a single pixel to be able to grab that window and move it. Decades of usability research thrown out the window thanks to Mac and web folks dictating the trends.

        Counterpoint: vertical tabs are way better

        • koolba 1 day ago

          Vertical tabs are only better because there is more horizontally space on a as screen and listing things vertical allows you to both gauge the list size and keep a mental reference of what slot a tab was. And those tab headers don’t move because of resizing when the width fills up.

          But horizontal tabs are still better. Not technically better or ascetically better. Some other immeasurable, indescribable better.

        Also with standard tabs. I mean it probably won't distub someone already conditioned by abhorrent MacOS design... but the lack of visual boundaries of tabs (independent controls), the terrible vertically uncentered close buttons, the whole thing is a visual Chernobyl meltdown... Mozilla working hard to kill Firefox.

        edit: just checked, and the most disgusting thing the extra internal horizontal top border of the text contents of the tab titles got removed. Still ugly, but nor instant Alt+F4... now I can bear it until I find about:config.

    • godelski 1 day ago

      I'm with you and honestly I think most people are. Frankly, I'm pretty certain that for 90% of users of you swapped chrome for Firefox, replacing the icons too, then people wouldn't notice. I'd wager 80% of HN users.

      It's such a petty argument when everything is so hackable and Google is eating the internet. I wish people would put half the energy they use to complain to solve the things they are upset about.

    • browningstreet 23 hours ago

      Just because you can’t see it doesn’t mean it isn’t ugly for others. Or will you just not allow others to have this opinion?

      It’s ugly.

      • preg_match 22 hours ago

        I think his point is that, even if you think it’s ugly, the nature of a web browser makes it irrelevant. The web browser is a window, 99.9% of the surface area goes to the website. Which is good. We could have prettier browsers which showed off more chrome, but that would be bad because we want to see the website.

        Also, the UX of most browsers is basically the same. Browser UI has converged on one layout that works, and Firefox has it. It’s really indistinguishable from chrome.

        • browningstreet 5 hours ago

          The allergy I have to some web browsers over others, even on iOS, makes that not a true assertion for me.

      The new sidebar design was unnecesary, a waste of space, and the rounded corner cutting into the website is flair with no functional purpose.

      The fact that I've historically needed to monkey patch the Firefox chrome CSS (and will have to again to remove the unnecessary bar left of tree-style-tabs) would to me imply poor design.

      Most people don't like Zen (or Arc). Which is fine. I'm a big keyboard person so I love it, especially with the vimium plugin. But sometimes people get confused at my browser because they don't know how to navigate. Which is understandable

      What I like about Mozilla is they made a hackable browser so we can have things like Zen, WaterFox, or whatever floats your boat.

      > why the hell would I sign up for a service that does what email/IMAP does in the first place?

      I don't know nor use the app promoted by GP, but in general the problem with apple is that they don't support the standard email/IMAP push, and only some 3rd parties have approval to use the non-standard apple email push (Fastmail I think). So people have come up with ways to get around apple's arbitrary restrictions.

      • al_borland 20 hours ago

        I recently switched to Fastmail. When I was asking an LLM about using it with the native Apple apps, it mentioned this approval that was needed, and that it didn't always work. I'd be interested to hear some first-hand experiences.

        My dad has been using his own domain for email for about 25 years and has bounced around to various hosts... random hosting providers. He uses Apple Mail and hasn't ever mentioned having an issue. Though I'm unsure if he uses push of fetch. I guess I always assumed he was using push, but maybe not.

        • brongondwana 20 hours ago

          It's pretty reliable. I'm actually quite amazed that it's been this long and Apple hasn't opened it more widely. We just happened to be in the right room at the right time to get a custom contract with Apple to have a signing key. The underlying tech is in a couple of open source projects.

          Of course we're all hoping that clients move to JMAP at some point, where push is first-class citizen and we don't need the very custom hack that Apple uses to receive pushes right now.

          • al_borland 20 hours ago

            That's good to hear. There's a lot to be said for being in the right place at the right time.

            I've been using the Fastmail app to get started, which has been working great and the migration tools worked really well. Once I'm fully migrated I may want to set up the native apps for some added OS integration.

      Haven’t dug into this yet, but are you saying it isn’t a pure eMail client? That it’s a service to which you bodily hand off all your eMail passwords, and therefore the keys to your digital kingdom? That it’s someone else’s computer that’s retrieving your eMails for you?

When I first saw the link, I thought, “Oh cool! A new platform using the Thunderbird name!”

Then I realized it was Mozilla’s app. And just like that, the excitement was gone.

I try not to bad-mouth products, but Thunderbird and I did NOT get along. Clunky integrations, a painful Gmail connection, and basic functionality issues made it one of the worst email clients I’ve ever used.

Of course, I’m also annoyingly picky about my tools, so maybe it’s a me problem.

    Many such cases. Duckduckgo is practically unusable because it just decides for itself which of my search terms it actually searches for. I have to explicitly quote every word to get it to function like a search engine.

    Meanwhile, Netflix search (on Apple TV at least), is not only practically unusable, but literally so. Doesn't matter what you input, it just returns a random selection of films. I saw Kill Bill the other day, and wondered if there were any other Tarantino films on there. "Tarantino" returned things like Indiana Jones and other completely nonsensical results.

      Netflix used to have codes you can search that were by category. I think it might work work on browser. Was a much better way to discover stuff (there's way more categories than you would expect)

What exactly is the Thunderbird team doing that I can't vibe-code with my special friend Claude? Why does this software justify a blog post about a "first look". What am I missing that is so exciting? I don't understand what is going on here that is so neat. There's nothing here I can't pump out in a week or two at worst.

I'm confused at everyone's excitement because it's become a lot cheaper to write software like this. Maybe for all the folks world-wide that aren't up to speed with modern practices, it's helpful to have an iOS app.

Am I talking like the guy that dissed Drew Houston, saying oh I can put together sshfs and a couple other things and build out Dropbox. Drew rightly corrected the engineer on ycombinator many years ago to say that end users want a finished product not a bunch of tools.
