Newton has been rebuilt and relaunched by the same owners who have run it for the last five years. Your old Newton account and mail didn't carry over, so you start with a new Newton account and add your email accounts again.
How it works
Who runs Newton. This isn't a new company or a new team using the old name. It's a relaunch by the people who already owned Newton.
Why it shut down before. Newton shut down in 2018, 2020 and 2024. Each time the cause was the same: the old service ran heavy servers that cost more than the app earned. The new Newton keeps its servers small, and subscriptions cover what it costs to run. That isn't a guarantee, but the thing that closed Newton before is no longer how it works.
Your old account and mail. Mail data was deleted when Newton shut down, for privacy reasons. Your old login, settings and signatures aren't in the new Newton.
What's familiar, and what's new. Read receipts, Snooze, Send later and the unified inbox are back. New are Recap, Tidy Inbox, a Linux app, and connecting Newton to Claude or ChatGPT. On desktop, the Agent answers questions about your mail using your own Claude Code.
To start again, install Newton, tap Get Started on a phone or click Sign up on a computer, and add your email accounts.
Good to know
Your mail at Gmail, Outlook, iCloud and other providers wasn't affected. Newton only deleted its own copy.
The desktop apps can do more than the mobile apps today, so some features reach your computer first.
