> Email Statistics: 347.3 billion emails sent daily without major issues, serving 4.37 billion email users worldwide as of 2023.

The average user receives 86 emails per day?! And I get a bit overwhelmed if I receive more than 3. Kinda puts things into perspective :-)

50% of that is spam that is blocked. At least 50% of the rest is spamish but not spam spam.

So don't feel too overwhelmed!

But is it spam spam spam spam?
dagw 7/1/2025||
I'm guessing for most people 80-85 of those 86 are caught by a spam filter and are never seen.

I wouldn't say Sparrow failed -- it got bought because it was successful. Did it reach its full potential? Certainly not. But certainly Google determined that it potentially could or it wouldn't have spent $MM to kill it.

>But they ignore the fundamental reality: email works perfectly for what it was designed to do.

Yeah the fundamental thing is email does it's job, and if you want to change that job in any dramatic fashion ... it no longer does its core job.

Actually recent email innovation I enjoyed is Mimestream, the macOS native client for Gmail. Apple’s smart inbox is half baked but better than nothing. Cloudflare now also has a pretty good email forwarding service.

Long article, but the fundamental premise is that IMAP, SMTP, and POP are all you need. And that email clients are good... This is just false IMHO. There is a reason why both Fastmail and Gmail implement their own protocols in addition to those.

But fundamentally the "folder" view of email does not work. A single message often needs to be in several different folders simultaneously. And when the thread is spread across many folders, there needs to be a way to see the whole thread.

The only way to accomplish this is with email tags or labels. These are implemented by nearly all successful email companies. Gmail, Fastmail, and Proton are examples. Labels are a fundamental feature in this day and age, and neither IMAP nor POP can handle them gracefully.

Gmail is so big that when Outlook, Apple Mail, and even Thunderbird connect to it, they do an OAuth exchange and then talk over a proprietary protocol.

JMAP may have poor adoption, but it's the only open protocol that understands labels well. The lack of adoption is mostly due to email providers not implementing it. There is not a lot of incentive for clients to implement it for the few providers. And providers would prefer you use their web clients anyway, as then they control access to your email.

Citation needed. This has never occurred to me.

Already possible, at least in Thunderbird.

IMAP has user-defined labels, whats wrong with them?

An underrated feature of IMAP is that you can attach notes to mails.

Can you elaborate? Anything I can read on this?

Just No. This is by far my biggest complaint of using Gmail.

It makes it impossible to write rules to file mail into folders as all you can do is add tags (labels). Whereas to _move_ you require the ability to unset and label which tags/labels don't support as thats a definining function of a folder.

Make Email Great Again! Now thats a campaign i'd be willing to fund!

This again is a limitation of mapping labels to IMAP, which does not understand labels.

Both the Gmail web interface and the Gmail API allow the ability to set all the labels for a message. This can effectively enable your desired functionality. But IMAP can only deal with "folders", and cannot correctly decide when to remove a single label or remove all other labels when it sees a move action.

IMAP also only deals in messages and not threads. Gmail labels also technically only apply to messages, but the web interface shows the union of all labels of a thread. This is another decision I agree with. It means that when someone explicitly adds me to a thread, the whole thread gets highlighted in my feed.

I personally really enjoy the Gmail/fastmail/proton behavior so please don't make another political campaign to make things worse again. We have enough of those.

Is 80% even that high? I thought the idea behind VC was to fund companies where 90% are doomed to fail, 9% might do okay, in order to cash in big on the 1% that have stellar success.

Am I way off with my numbers there?

My god this "article" is an inconsistent pile of AI slop. It actively contridicts itself and changes the thesis several times as it goes on and on and on.

Not sure why they attack Fastmail and JMAP all the time.

> Gmail's threading: Enhanced email organization

Gmail's threading is an abomination.

"If you want to fork a thread, just change the subject!" This idea is so brain-dead and antithetical to deep mailing list conversations.

"Oops too many people replied, guess gmail'll fork the thread without changing the subject"

My disdain for this misfeature is palpable.

That text reads weird. It is actually continuous text but randomly changes to headlines and inline notes and graphics.
