FlowMail is an email client with a Kanban board built in: move messages into To Do, In Progress and Done, and your inbox becomes a list of things to finish rather than a pile to reread. Workflows and AI run on your iPhone and iPad by default. 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, summarize, classify, transform text, send an email now or later, 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
AI steps run a model you pick locally, on Apple's MLX, and send us nothing. Pro can use Google Gemini on your own key instead, once you turn it on.
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.
