an app by robspace
Your Gmail, sorted into pigeonholes. See at a glance where mail is waiting, turn mail into ToDos, and let the morning briefing show what needs a reply. Your mail travels only between Gmail and your device.
For iPhone, iPad and Mac. Requires iOS 26, iPadOS 26 or macOS 26 or later.
4Mail by robspace is an independent email app by robspace. It is not a Google product. Gmail is a trademark of Google LLC.
4Mail shows your mailbox like the pigeonhole wall of a post office: every pigeonhole shows how much is in it. Empty ones are sunk in, full ones stand out.
The home screen is a set of tiles, the pigeonholes. A pigeonhole is a Gmail label, one of your addresses, or a saved search. Unread mail shows as a big number in each one. Every pigeonhole gets a colour and a symbol, and you arrange them as you like.
If your Gmail account has several "send as" addresses, each gets its own colour and a stamp with initials. On every mail you see which address it was sent to, and "Reply as" answers from the right one.
Turn a mail into a ToDo with one tap: with or without a due date, with a note and a snooze ("Wiedervorlage"). The ToDo tab sorts by due date. For each pigeonhole you can have new mail become ToDos automatically (off by default). In Gmail, 4Mail creates the label "4Mail/ToDo" once for this.
One list for what comes next: appointments from your iOS calendar, your ToDos, and invitations from your mail, each on its day. 4Mail never adds an appointment from mail on its own. You confirm every suggestion in the calendar editor.
The Briefing tab shows what happened since yesterday: how many new mails, which replies are due, what is on today, which newsletters you can archive. 4Mail counts the numbers itself. Apple Intelligence words the summary sentence and summarises single mails. The briefing names a deadline only when the mail states it, and every statement links to its mail. The AI runs on your device, not in the cloud. Without Apple Intelligence the briefing keeps counting, just without summaries. AI can be wrong, so every line shows its source.
Search shows matches from your device instantly and adds results from Gmail. "from Mia attachment" turns into filters that you confirm. A good search can become a pigeonhole on the wall.
For newsletters that offer an unsubscribe header, 4Mail shows a button. You are unsubscribed only after you confirm a dialog that names the destination.
For each pigeonhole you choose whether notifications arrive and whether they show a preview. Without a preview the lock screen only says "New mail in …". The app creates the notifications locally on your device; there is no push server.
4Mail blocks images and tracking pixels in mail until you tap "Load images". Scripts in mail never run. Links open only after a prompt that shows the destination.
On iPad a sidebar shows pigeonholes and tabs next to the list and the reader, and you can drag mail into a pigeonhole, into the ToDo tab or onto a day. On the Mac you also get windows and keyboard shortcuts.
Besides Gmail, 4Mail also connects IMAP accounts, for example iCloud Mail, GMX, web.de, T-Online, Posteo or mailbox.org. For well-known providers 4Mail fills in the servers itself; otherwise it asks your provider's domain or you enter them. The connection always goes encrypted and directly to your provider, and your password stays in this device's keychain. All accounts can share one inbox. Outlook.com/Hotmail and Proton Mail do not work with 4Mail (Microsoft requires its own sign-in, Proton only works with its own apps or Bridge).
4Mail speaks English and German and follows your device language.
4Mail talks directly to Google, and for IMAP accounts directly to your mail provider. There is no robspace server that your mail passes through. We cannot read it.
What the app stores lives on your device and is excluded from device backups. When you sign out, 4Mail revokes its access at Google and deletes the mail data from the device.
gmail.modify: read, write, organise and send mail), no calendar, no contacts, no Drive. It cannot delete permanently.4Mail's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
No. There is no robspace server in the middle. 4Mail connects your device directly to Gmail.
One permission: read, compose, organise and send mail (gmail.modify). 4Mail never sees your Google password. You can withdraw access at any time at myaccount.google.com/permissions or with "Sign out" in Settings.
No. Pigeonholes, ToDos, agenda, search and the numbers in the briefing work without it. Summaries and the detection of "reply due" and deadlines need Apple Intelligence on a supported device. Without it the briefing counts by fixed rules.
No. 4Mail uses only the on-device model, not Apple's Private Cloud Compute.
Yes, via IMAP: for example iCloud Mail, GMX, web.de, T-Online, Posteo and mailbox.org. Gmail is connected with "Sign in with Google". Outlook.com/Hotmail and Proton Mail are not supported.
4Mail revokes its access at Google and deletes mail data, search index, briefing and attachments from the device. If you wish, you keep your own ToDos that have no mail. Details are in the privacy policy (section "Signing out").
iOS 26, iPadOS 26 or macOS 26 or later.
