Self-Hosted Email Is Getting Its Arse Kicked, and the Usual Megacorps Are Winning

Right, here’s the miserable gist. The article says self-hosted email has dropped to about 22.4% of the market, which means fewer poor bastards are running their own mail servers and more of the planet is handing the whole bloody mess over to Google and Microsoft. Because apparently people have decided that dealing with spam, deliverability, blacklists, TLS, DKIM, SPF, DMARC, and every other flaming mail-related pain in the arse just isn’t worth the suffering anymore. Can’t say I blame them, but it’s still a bit shit.

Google and Microsoft now control a huge chunk of the email world, because of course they do. If there’s a critical service on the internet, some gigantic corporation will eventually hoover it up, slap a management portal on it, and charge you monthly for the privilege of becoming dependent on their ecosystem. Email, that ancient undead cockroach of the internet, is no exception.

The article points out that self-hosting email has become increasingly difficult. Not because sending a bloody message is complicated in itself, but because the modern email ecosystem is packed with gatekeeping bullshit. You can set up your own server just fine, but getting other systems to trust your mail without dumping it into spam hell is where the real bastardry begins. Reputation systems, anti-spam controls, IP trust, DNS records, reverse DNS, signing policies, and a mountain of fiddly configuration mean that one tiny screw-up can make your mail vanish into the void. Wonderful design, really. Absolute masterpiece of institutionalised pain.

Meanwhile, businesses are moving to cloud-hosted mail because it’s easier, more predictable, and doesn’t require some sleep-deprived admin to spend half the week figuring out why Outlook thinks the CEO’s invoice email looks like Nigerian prince spam. Microsoft 365 and Google Workspace promise convenience, security tooling, compliance features, and central management. In other words: fewer moving parts for local admins to babysit, and more power concentrated in the hands of the same companies that already know too much about everyone.

The piece also makes it clear that this isn’t just about laziness. Running mail properly now takes expertise, time, maintenance, and infrastructure that many organisations no longer want to bloody well own. Smaller firms especially can’t justify the hassle when cloud platforms offer bundled mail, calendars, collaboration tools, identity integration, and support contracts. Why wrestle with postfix logs at 2 a.m. when you can pay a vendor and let someone else absorb the screaming?

Still, the decline of self-hosted mail comes with a price. Less diversity, more centralisation, and more reliance on a handful of giant providers. That means if Google or Microsoft changes policy, screws up filtering, has an outage, or decides your setup looks “suspicious,” a vast number of people get shafted at once. It’s efficient, yes, but it also means the email universe is increasingly run by a small club of corporate overlords. Marvellous. Nothing says resilience like putting everyone’s communications eggs in the same two bloody baskets.

So the article’s bottom line is this: self-hosted email is shrinking because it’s become a colossal, tedious, failure-prone pain in the arse, while Google and Microsoft keep gobbling up the market by making outsourced email easier to swallow. It’s practical, it’s understandable, and it’s also a little depressing if you give a damn about decentralisation. But then, the internet’s been drifting toward “five companies own everything” for years, so this is just another shovel of dirt on the same grave.

Reminds me of a place where management insisted on self-hosting everything for “control,” right up until their mail server got blacklisted, invoices stopped arriving, and the sales director started bellowing like a wounded pig. Three days later they migrated to Microsoft 365, called it a strategic transformation, and gave themselves a pat on the back for fixing the disaster they created. Same shit, different decade.
