FlowMail
email that flows
Free · In‑App Purchases
Your inbox as a list, a Kanban board or a graph. Mail, automation and AI that run on your iPhone and iPad — not on anyone's server.
FlowMail is an email client that lets you look at the same mail three ways — as a list when that is all you need, as a Kanban board when you are working through it, and as a graph when you need to see how a conversation actually unfolded. It is the same app on iPhone, iPad and Mac, and it runs on your device. There is no FlowMail server.
WORK YOUR INBOX LIKE A BOARD
Move messages between columns — To Do, In Progress, Done — without leaving your mail. A message keeps its board position as mail syncs, so the board is a real working state rather than a view you rebuild each morning. Kanban is in the free version.
SEE THE SHAPE OF A CONVERSATION
The Graph view lays a thread out as a force-directed graph — who replied to whom, where it forked, who went quiet. Useful when a long thread has stopped making sense as a stack of quoted replies. On iPad it takes the whole screen.
CHECK WHO REALLY SENT IT
Ask any message whether it is what it claims to be. FlowMail checks the domains in the thread and whether you have the message it replies to, and says what it found. To know who owns a domain, it fetches the public suffix list from publicsuffix.org once a day, sending nothing about you (you can turn this off). A lookup server and an on-device model are off until you turn them on; the lookup sends domains and hashes, never the message.
READ MAIL IN YOUR OWN LANGUAGE
Translate a message in place, keeping its formatting and its quoted history. It uses Apple's on-device translation, so the mail you are reading does not leave your device to be read by a service.
WORKS WITH THE MAIL YOU ALREADY HAVE
Microsoft — Outlook, Hotmail, Office 365 — and Google, through their own sign-in pages, so your password is never typed into FlowMail. iCloud, Yahoo, Fastmail and anything else that speaks IMAP and SMTP, with server settings looked up for you. As many accounts as you like, on either tier.
MAIL THAT ARRIVES WHEN IT ARRIVES
Live sync holds an open connection to your Inbox, Sent and Archive folders while the app is open, and background refresh keeps the mailbox current when it is not. Notifications are grouped rather than one per message, and tapping one opens that message.
FIND IT, AND ACT ON IT
Search runs over your whole mailbox rather than a recent window of it. Filter the list down to what you have replied to, or what you have not. Select several messages and archive, flag or delete them in one go.
AUTOMATE THE PARTS YOU REPEAT
Build workflows from steps: find messages, apply or remove a label, move a card on the board, draft a reply, summarise, classify, transform text, fetch a web page, or call a tool on your own MCP server. Run them from the app, from Siri, from Spotlight, or from a Shortcut — ten Shortcuts actions ship with it, from Compose Email to Find Emails.
AI THAT RUNS ON YOUR DEVICE
FlowMail's AI steps use a language model running locally, on Apple's MLX. You pick the model. Message content is not sent to us or to any AI provider.
OPEN WHAT LANDS IN YOUR INBOX
Read .eml, .msg, .vcf and .ics files directly. A contact or an event can be added to Contacts or Calendar with one tap — and until you tap, FlowMail never touches either.
PRIVATE BY DESIGN
Your messages are stored on your device. red8.io never receives, stores or processes them, and there is no account to create with us. Sign-in tokens and app passwords live in the Keychain. There is no analytics, no advertising and no crash reporting in the app.
FREE, AND PRO

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Workflows can now run on their own: when a message arrives, when its Kanban status or label changes, or on a schedule, including mail fetched in the background. The Workflows list shows which ones are switched on.
- New Message, Reply and Forward now open on iPhone.
- Forward a message, with its attachments.
- Move messages to another folder with Move to….
- Attach files to any message from the paperclip.
- FlowMail is now available in French and German.
- Translate works on messages written in two languages, shows that it is working, and says why when a translation is not possible.
- Verify no longer closes FlowMail on iPhone, and now tells different sites apart on shared hosting such as github.io.
- iCloud account sync now adds the accounts from your other devices instead of replacing yours, and an account you remove is removed everywhere.
- Pinch to zoom in the graphs stays under your fingers, and searching the People graph works.
- Fixes: Reply All no longer copies you on your own reply; Pro unlocks as soon as you subscribe, and Settings › Pro names your plan; Settings opens on its list of pages.
