Futo v0.1

FAQ

Updated November 2026

What do I need to run Futo?

A Mac with macOS 15 Sequoia or later.

Which mail accounts work with Futo?

Any account you can reach over IMAP. Gmail, iCloud, Outlook, Fastmail, Yahoo, AOL, Zoho and GMX are set up for you.

For any other address, Futo looks up the settings from its domain, and you can always enter them yourself.

How do I sign in to Gmail?

With Google's own sign-in, in the system's sign-in window, so Futo never sees your Google password.

Other accounts sign in with your password, or an app password where your provider asks for one.

Can I try Futo without connecting my mail?

Yes. Futo comes with a sample mailbox you can open on the first screen. Nothing in it touches the network.

Can I use more than one account?

Yes. Each account is its own space, with a colour, icon and name you choose. Swipe the sidebar to move between them.

To read everything at once, open the combined inbox with ⌃0.

Can I take back an email I just sent?

Yes. Every message waits a few seconds before it leaves, so you can undo it from the notice that appears. Choose how long, or turn it off, in Settings › Composing.

Messages you write while offline wait in an outbox and go out as soon as you're back online, even if you quit Futo in between.

How do I quiet a busy conversation?

Mute it from the message's More menu or by right-clicking it in the list. New replies still arrive, but without a notification.

For newsletters, Futo shows an Unsubscribe button when the sender offers one, and takes care of the rest.

Can Futo be my default mail app?

Yes, in Settings › General. Email links anywhere on your Mac then open a new message in Futo.

Why are the pictures in some emails hidden?

Futo doesn't load pictures from the web until you allow it. Many emails carry tiny tracking images that tell the sender when, and where, you opened them.

You can allow them for one message, or always for a sender you trust.

Why do some emails stay white in dark mode?

Plain emails follow your Mac's appearance. Emails that bring their own colours, pictures or layout, like newsletters or a signature with a logo, keep the white page they were designed for, so nothing ends up unreadable.

Show Original Appearance in the More menu shows any message exactly as it was sent.

Does Futo collect any data?

No. There's no analytics in Futo and no account with us. It talks to your mail servers, to Google or Microsoft if you sign in with them, and looks up an account's settings by its domain when you add it.

Your passwords are stored only in your Mac's Keychain.

Will Futo have AI features?

Yes, they're on the roadmap: help with what matters first, summaries of long threads, and first drafts of replies.

They'll run entirely on your Mac. Your mail won't be sent to a cloud AI service, ours or anyone else's, and it won't be used to train models. If a feature can't work on your own device, it won't be in Futo.

Do reminders and muted conversations sync between my Macs?

Not yet. Both are kept on the Mac where you set them.

Is there an iPhone app?

Not at the moment. Futo is made for the Mac.

Why a stamp?

Because mail used to need one. The colour of the stamp keeps time with yours, from indigo at night to gold in the morning: on the home page, drag it sideways to turn the day.
