The email client
you buy once.
Every other inbox wants a monthly payment. Kanmail doesn’t. Pay $49 once and it’s yours, on Mac, Windows and Linux, for as long as you use it.
What are you even renting?
A subscription email client keeps charging for software that runs on your own machine. Kanmail charges you exactly once.
Why does an email client need a subscription anyway?
It’s a fair question, and most apps don’t really answer it. You’re not buying storage, that’s your provider’s job. You’re not buying server costs, a good desktop client talks straight to your inbox. So what exactly are you renting, month after month, for software that lives on your own machine?
For a lot of people the honest answer is: nothing they can point to. The subscription isn’t there because the app costs that much to run on your laptop — it’s there because recurring revenue is good for the company. Reasonable thing for a company to want. Just not obviously a good deal for you, for a tool you’ll open every day for years.
Kanmail takes the older bargain. You pay once, you own that version, and there’s no meter running in the background.
One payment, then nothing.
$49 for a perpetual license. Use it for five years and your total cost is still $49.
No hostage situation.
Subscription apps stop working the day you stop paying. The version you bought keeps working forever.
Try it for real, first.
Free to evaluate for as long as you need. You decide it’s worth $49 after you’ve lived in it, not before.
It’s not just cheaper, it’s built differently.
Buying once is the headline. Here's why the app itself is awesome.
Your inbox as a
kanban board.
Instead of one endless scroll, email becomes columns you move things through — To Do, Waiting, Done. Every message is a card you pick up and drag. The layout matches how you already think.
All your accounts,
one board.
Gmail, Fastmail, iCloud, Yahoo, Yandex or any IMAP/SMTP provider, unified into a single board instead of a tab per account.
Privacy that isn’t
a marketing word.
Kanmail talks directly to your provider. Your mail never passes through anyone else’s servers.
Tracking pixels stripped
Remote images are hidden by default, so senders can’t tell when, or whether, you opened anything.
Straight to your provider
No middleman servers between you and your inbox. Nothing to scan, nothing to profile.
Unsubscribe from inside
Kill mailing lists without ever visiting a sketchy unsubscribe page again.
Runs where you do.
Mac, Windows and Linux. The same app, the same license. If you live on Linux, you already know how short the list of decent paid clients is. This is one of them.
Who Kanmail is — and isn’t — for
You’ll probably love it if
- ✓You’re drowning in multiple email accounts
- ✓You think about your inbox in tasks
- ✓You’re quietly tired of renting software that runs on your own computer
It’s probably not for you if
- —You need a polished phone client as your primary inbox
- —You love a classic single-list inbox and don’t want a kanban shift
If that’s you, the trial costs nothing and the math is simple.
