If you're reading this, you probably remember Newton. The quiet of it, maybe. An inbox that felt calm instead of like a fight you were losing. Snoozing an email until the moment you could actually deal with it. Knowing the second someone read the message you'd been waiting on. And, if we're being honest, you might also remember the bad part: opening the app one day and finding out it was going away. Again.

So here's the headline. Newton is back. Not a fresh coat of paint on the old thing. Not a nostalgia tour. We rebuilt it properly, and we did it to fix the one problem that kept ending the story early.

This is really for two groups of people. If you used Newton before, consider this us welcoming you back and being upfront about what's changed. And if you've never heard of it, this is the quick version of why a little email app earned the kind of loyalty that makes people ask, for years, whether it's ever coming back.

Let's talk about the shutdowns

Newton has shut down before. More than once. We're not going to tiptoe around that, because tiptoeing around it is exactly the sort of thing that would prove you right to be skeptical.

One of the problems we set out to address was the infrastructure behind Newton. The old app depended heavily on server-side systems for syncing, receipts, and connected services. That infrastructure brought ongoing costs and maintenance work. When we rebuilt Newton, reducing that dependence was a priority. Bringing back the experience people loved also meant rethinking what it took to keep it running.

We're telling you this because it's the reason the next bit actually means something.

What we kept

When you rebuild something people loved, the first rule is don't wreck the part they loved it for. So we were careful about what came along.

The feeling, first. Nobody ever described Newton with a spec sheet. They talked about how it made email feel. One person told us it was "more relaxing doing email than Gmail." Someone else said Newton helped them "get your life back" and called it their "secret weapon." That calm, the sense that your inbox is somewhere you visit on your own terms instead of something that yanks at you all day, is the whole point. It's still here.

Then the craft. Newton won a Webby for design twice, and that was never just decoration. A clean, fast, good-looking app is how you get to calm in the first place. We held that bar.

And the features that made it feel like a cheat code are here: read receipts so you're not left guessing, snooze to push things off until they matter, send later for when timing counts, and one unified inbox across your accounts. They're also the first things returning users ask about. They made the cut.

What's actually different this time

Here's where the new Newton parts ways with the old one, and it's not something you'll spot in a menu. It's the plumbing underneath.

Start with your mail. Newton doesn't store your mailboxes on its servers. Mail syncs on your device. On iPhone and Android, that includes native IMAP syncing: the app connects to your mail server directly to sync your messages, without routing that sync through Newton.

That changes what we're responsible for running. Each new account doesn't mean another mailbox for Newton to store and continuously sync on your behalf. Your email provider holds your mailbox, and your device does the syncing.

Newton still has a backend. Notifications, scheduled sending, collaboration, and some AI features need services behind them. Those services cost money to run, and that cost can grow as more people use them. But adding users doesn't require us to build and maintain a central copy of everyone's mail.

That's the concrete difference in this rebuild. It doesn't make running Newton free, and it doesn't guarantee the future. It removes the storage and syncing burden of hosting your mailboxes ourselves.

After Newton's history, you deserve more than another promise that we'll stick around. These are decisions you can look at and question. The rest we have to earn through the app working reliably, problems getting fixed, and the team continuing to show up.

Where things stand right now

Newton is live today on Mac, Windows, Linux, iPhone, iPad, and Android. It works with Gmail and Outlook, as well as iCloud, Yahoo, Fastmail, Zoho, and other supported IMAP accounts. If you were waiting for mobile or for your mailbox to be supported, there's now more for you to come back to.

The familiar features have some company, too. Tidy Inbox moves lower-priority mail into a separate view, with controls for how individual senders are treated. Today uses AI to help surface messages that may need your attention. Both build on something we've always cared about: helping you decide what deserves your time when you open your inbox.

There are also AI tools to help draft and refine replies, translation for messages in another language, and shared inboxes and collaboration for teams. For people who use compatible AI assistants, Newton supports connections through MCP, with access to your email controlled by the permissions you approve.

It's still getting better with the people using it. Features vary by platform and email provider, and we're continuing to close gaps and improve the everyday experience. You can follow what's changed in our changelog and tell us what you need through our feedback board.

Come have a look

We're not going to wrap this up with a hard sell, because that's not really what today is about. After everything, the honest feeling is mostly gratitude. To the people who kept asking. Who emailed wondering if it was coming back. Who just wouldn't let a good thing be forgotten.

Newton is back. We're building it carefully, with foundations we've rethought and a lot of everyday work still ahead of us. If you want to see for yourself, come take a look. The door's open, and we're glad you're here.

Welcome back.
