Your Gmail, with the part Gmail leaves out.

Keep using Gmail and Google Workspace. Mills Super Mail sits on top, reads your mail straight from Google, and adds what you need to follow up at the right time.

See every open and every click

Turn on a read receipt as you write, or leave it on for everything. You see when each email was opened, how many times, and which links were clicked. Opens from spam scanners and Apple's privacy proxy are marked so you know which ones were really a person.

Alerts that reach your lock screen

When someone opens your email, your iPhone tells you right away, even with the app closed. New mail shows who it is from, the subject and the first line. Promotions and social mail stay quiet.

Mills Super Mail is in early access while Google completes its security review of the app. Until then sign-up is open to the first 100 people, and Google shows a one-time notice that the app is still being verified.

Your email stays your email.

Here is what happens to your data, in plain words. The full details are in the privacy policy.

Your mail is not stored on our servers
The app loads your email straight from Google each time. We keep only what the features need, like the subject and send time of emails you track.
We never sell or share it
No ads, no data brokers, and your email is never used to train AI models.
Other people's trackers are blocked
Read receipts in emails you receive are stripped out, so senders do not see when you read them.
Leave whenever you want
Delete your account in Settings and everything we hold is erased, and our access to Google is removed.
