## What is FlowMail?

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.

FREE, AND PRO
Free is a complete email client: unlimited accounts, the List and Kanban views, search, live sync, notifications and one workflow. Pro adds the Graph view, unlimited workflows and on-device AI triage, as a monthly or yearly subscription with a free trial. A subscription covers iPhone, iPad and Mac.

Requires iOS or iPadOS 18.6 or later. In English, French, German and Brazilian Portuguese.

## Version history (last 4 releases)

### 26.5 — 2026-11-06

- Send a message later: touch and hold Send and pick a date and time. It waits under Scheduled in the sidebar, and if FlowMail is closed at that time, it goes the next time FlowMail runs.
- Undo: after you delete, archive, move, flag or mark messages, shake to undo and each one goes back as it was. Delete now moves messages to Trash.
- Export all of an account's mail: Settings › Accounts › Export Mail… saves every message as .eml and mbox files, with its attachments and an index you can open in a spreadsheet.
- Workflows can send email, now, after a delay or at a time of day, with the new Send Email step.
- Pro: run your workflows' AI steps on Google Gemini, with your own API key. On-device AI stays the default.
- Sync is much faster: accounts sync side by side, Inbox messages download first, and an opened message loads in a second or two.
- A message you send appears in Sent within seconds, and FlowMail recognizes Sent, Trash and Junk folders in any language.
- Verify no longer flags ordinary mail between companies, and shows a failed DMARC check.
- Pro is now a monthly or yearly subscription. If you bought the lifetime unlock, you keep Pro.
- Fixes: on iPhone, a new message, a reply or a forward starts right under the subject; All Inboxes names each message's account, on the board and the graph too; a message that cannot be downloaded says why and offers Try Again; messages you send no longer carry your device's name; the same message is no longer listed twice.

### 26.4 — 2026-10-12

- 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.

### 26.3 — 2026-09-25

- Invitations and contact cards that arrive by email now open inside FlowMail, with Add to Calendar and Add to Contacts one tap away.
- Invitation times are read in the time zone they were sent in, including Outlook's, so a 14:00 meeting in Berlin shows at the right hour where you are. All-day events are saved as all-day.
- If an invitation uses a time zone FlowMail doesn't recognise, the card says so rather than quietly showing a wrong time.
- Permission prompts are now in Brazilian Portuguese as well as English.
- Attachment sizes now use the right unit, so a small file no longer shows as "0 KB".
- The welcome screen now introduces Verify, and marks the Conversation Graph as part of FlowMail Pro.
