Add an account

On the Mac, open the account menu at the top right and choose Add Google account, or press ⌘K and type "add". On iPhone, hold the round account button at the bottom of the inbox and tap Add account.

Switch on the Mac

⌃1 opens your first account, ⌃2 your second, and so on up to ⌃9. The account menu at the top right lists every account with its unread count, and shows a dot when another account has new mail. Drag accounts into the order you want in Settings. Supermail opens on the first one.

Switch on iPhone

The round button at the bottom of the inbox shows which account you're in.

• Tap it to jump to your next account. After the last one, it goes back to the first.
• Hold it for every account with its unread count, plus Drafts, Sent, Reminders and Settings.

Each account shows its first letter on the button. Hold an account in that list to give it a picture instead.

Supermail loads your other accounts ahead of time on both the Mac and iPhone, so a switch doesn't wait on a spinner.

Your other addresses

If you send from more than one address in Gmail, like you@ and sales@, Supermail knows they're all you:

• Mail you sent from any of them says "me", like in Gmail.
• A reply goes out from the address the email was sent to, with that address's name and signature.
• On the Mac, ⌘⇧F picks a different From address while you write.

Each account keeps its own

Super Labels and colors are set for each account. Settings like Undo Send and the forgotten-attachment check apply to every account on the device.

To take an account out, open Settings, choose the account, then Remove Account. Supermail deletes that account's mail from the device. Nothing in Gmail changes.

Important and Other

Every account starts with two:

• Other catches bulk mail you haven't answered: newsletters, notifications, receipts and anything from a noreply address. It also takes what Gmail files under Promotions, Social, Forums or Updates.
• Important gets everything else, which is mostly email from people.

The number next to each name is how many conversations are in it. Prefer one inbox? Settings → your account → Super Labels switches to "One Inbox tab".

Move between them

On the Mac, Tab goes to the next Super Label and ⇧Tab goes back. You can also click one. On iPhone, they sit at the bottom of the inbox, in reach of your thumb, and they're in the ☰ menu too.

Add your own (Mac)

Any Gmail label can be a Super Label. Mail with that label shows in its own tab instead of Important or Other.

• From an email: ⌘K → Make a Super Label from This Email fills in the sender. One click switches it to everyone at their company.
• From scratch: ⌘K → New Super Label. Fill in any of From, To, Subject and Has the words, the same way you'd search Gmail.
• From a label you already have: Settings → your account → Super Labels → Add Super Label.

When you make a new one, Supermail creates the Gmail label, puts it on the mail that matches now (up to the newest 5,000 emails), and opens the new tab. New mail that matches later won't get the label by itself yet. To label new mail as it arrives, add a filter for that label in Gmail.

In Settings → your account → Super Labels you can rename them, drag them into a new order, or remove one. Removing a Super Label never changes Gmail: the label stays, and its mail goes back to Important or Other.

Give them colors

Settings → Colors → Super Labels puts a colored dot by each name. Pick your own color, or use the label's color from Gmail.

A few things to know

• Super Labels belong to each account, so your work account and your personal account can be set up differently.
• They're kept on the Mac you set them up on. On iPhone, every account shows Important and Other for now.

The fastest way to learn them is the tutorial. Press ⌘K, type "tutorial" and press Return. It opens a practice inbox full of made-up email, so nothing you do there touches your real mail.

Five short lessons

1. Moving around. J moves down your inbox and K moves back up. Return opens an email and Esc takes you back.
2. Inbox zero. E marks an email done. It leaves your inbox and stays in Gmail. H sets it aside until a time you type, like "tomorrow 9am". Z undoes almost anything.
3. Replying. R replies, A replies to everyone and ⌘↩ sends. C starts a new email. Close a draft with Esc and ⌘D brings it back.
4. Search and Super Labels. / searches, and Gmail's search words work too, like from:dana. Tab moves to the next Super Label, the tabs across the top of your inbox.
5. Every shortcut in ⌘K. ⌘K lists every command with its key. It's your cheat sheet.

Each step waits until you've done it, then moves on. If you get stuck, Show me does it for you.

Handle a stack of email at once

Press ⇧J to select an email and the one below it, and keep pressing for more. Then E, H, L or # works on all of them at once. After a search, ⌘A selects every match.

Labels without the mouse

L opens the label box. Type a label you already have, or a new name, and Supermail creates that label in Gmail. Z takes back any label you add or remove.

Find the rest in ⌘K

There are many more keys. You don't need to memorize them. Press ⌘K, type what you want to do, like "star" or "label", and the key is listed right next to it.

Plenty of people have an Outlook account for work and a Gmail account for everything else. We want both in one app, run from the same keyboard.

If you use Outlook, say so when you request access below. It helps us know who to tell first.

Results as you type

Press / on the Mac, or pull your inbox down on iPhone, and start typing. Matches from the mail saved on your device show up right away, before anything goes to Gmail.

On the Mac, ↓ picks one and Return opens it. Press Return with nothing picked and you get every result, including Gmail's. On iPhone, tap Search on the keyboard to ask Gmail.

1. Gmail's search words

Everything you use in Gmail works here: from:dana, has:attachment, after:2026/9/1, "an exact phrase" and the rest. Supermail sends the search to Gmail, so you get what Gmail would find.

2. Type a sentence

Type "invoices from Tom last month" and Supermail turns it into the right Gmail search. The line under the box shows the search it made. Tab lets you edit it, and ⇧Tab searches your own words instead.

It understands:

• who sent it or got it, by name, from people you've emailed with
• dates like "last month", "since Monday" or "in August"
• unread and starred
• kinds of files: PDFs, spreadsheets, Word documents, slides and photos

It runs on your device with Apple Intelligence, and nothing it reads is sent to any AI service. It needs macOS 26 or iOS 26 with Apple Intelligence on, in a language it supports. Without it, search works exactly as you type it.

3. The search form (Mac)

Click the sliders button in the search box, or press ⌘K and choose Advanced Search. Fill in any of From, To, Subject, Has the words, Doesn't have, size, a date range, where to look (All Mail, Inbox, Sent Mail, any label) and Has attachment. Tab moves between fields and Return searches.

Then deal with all of them

After a search, ⌘A selects every match, up to 1,000, including older ones that weren't on your device yet. Press E and they're all done.

Undo Send, on your timer

When you press Send, Supermail holds the email on your device before it goes to Gmail. Press Z on the Mac, or tap Undo on iPhone, and it comes back as a draft, ready to fix.

Settings → Writing sets how long it waits: 5, 10, 20 or 30 seconds, the same choices Gmail gives you. The Mac starts at 10 seconds and iPhone at 5. Your pick follows you to your other Macs and your iPhone.

The forgotten-attachment check

Write "attached is the invoice" or "see attached", forget the file, and Supermail stops you before anything goes out:

Did you forget an attachment? You wrote "Attached is the signed quote", but nothing is attached.

On the Mac, Return takes you back to the draft, ⌘⇧A attaches files and ⌘↩ sends it anyway. On iPhone, the same question offers Attach Photo, Attach File, Send Anyway and Cancel.

It only reads what you typed in this draft. "I've attached the invoice" in the email you're answering never sets it off, and neither does your signature. The check runs on your device, so your draft goes nowhere new.

Don't want it? Settings → Writing → Attachment check turns it off.

Your mail is already on your device

Supermail keeps a copy of your mail on your Mac and iPhone, encrypted. When you open the app, your inbox comes from that copy, not from a trip to Gmail. Every 15 seconds, Supermail asks Gmail what changed and downloads only those conversations.

Every action shows up first

Press E, swipe an email away or add a label, and the screen changes right away. Supermail tells Gmail in the background. If Gmail says no, the email goes back where it was and Supermail tells you. Z undoes your last 30 actions.

Emails open before you click

Supermail downloads the emails you're most likely to read next: the top of your inbox, the ones right around the email you're reading, and the top search results.

Search starts before Gmail answers

Matches from the mail on your device appear as you type. Gmail's results join them when they arrive.

Swipes and switches without the wait

On iPhone, a full swipe acts the moment your finger lets go. The email slides away and the next one moves up in a fraction of a second.

Your other accounts load ahead of time on the Mac and iPhone, so switching accounts doesn't wait on a spinner.

Your hands stay on the keyboard

The biggest speedup is not reaching for the mouse. J and K move, E marks done, H sets an email aside, R replies and ⌘K finds everything else. Learn them in a few minutes with the practice inbox.
