Flint servers between you and your mail
5+
providers, plus any IMAP account
100%
of your mail stored on your iPhone

Built like a messenger.
Works like email.

Underneath the bubbles it's real, full-fat email, sent from your own address and synced with your provider.

Chats, not threads

Replies are bubbles, not a wall of quoted history. Catching up on a conversation takes seconds.

All your accounts

Gmail, Outlook, iCloud, Yahoo and AOL in one app, with instant account switching.

Private by design

Flint has no mail servers. Your messages and credentials live on your iPhone and nowhere else.

Search everything

Your whole mailbox is cached on-device, so search is instant, even in Airplane Mode.

Sending you can trust

Outgoing mail is queued safely on your device and sent exactly once. Never lost, never duplicated.

Everything stays in sync

Reads, sends and deletes sync back to your provider, so every other device stays up to date.

No servers. Seriously.

Most email apps route your mail through their cloud. Flint doesn't have one. Mail syncs directly between your iPhone and your provider, and your sign-in stays in the iOS Keychain.

Questions, answered.

How is Flint different from Mail or Gmail?

Traditional apps show email the way servers store it: threads full of quoted history, subject lines, and signatures. Flint reads the thread for you and shows just what each person actually said, as chat bubbles, grouped by sender, newest at the bottom. It feels like Messages, but every message is real email.

Which accounts can I connect?

Gmail and Google Workspace, Outlook and Microsoft 365, iCloud Mail, Yahoo, AOL, and any standard IMAP mailbox. You can connect several at once and switch instantly.

Where is my email stored?

On your iPhone, in an encrypted local cache. That's also why search and scrolling are instant. Flint talks directly to your mail provider; there is no Flint cloud in between, and your credentials never leave the iOS Keychain.

Do my replies look weird to other people?

No. What you send is a normal email, from your normal address, with proper reply threading. Recipients can't tell you sent it from Flint.

When can I get it?

Flint is in final testing and coming soon to the App Store for iPhone. It will be free to download at launch.
