Frequently asked questions

Yes, that is exactly what Gadfly is. Mark any email as a to-do and it gets a deadline read from the mail itself. Then Gadfly keeps the pressure on: the to-do moves from calm to hot to burning to critical as the date nears, you get a push before it is due, and the hottest ones sit on your iPhone lock screen until you finish them.

Gadfly launches on Mac, Windows, Linux, iPhone and Android on the same day. Leave your email on this site and you get one mail when it is out. Early sign-ups get 3 months of Pro free instead of the usual 30 days.

Snooze and remind-me bring a mail back once, then it is on you again. A Gadfly to-do never goes quiet until it is done, dropped on purpose, or snoozed by you: it has a date, it climbs through four pressure bands, and it stays on your Chase list, widgets and lock screen.

Gadfly is built by an owner of several businesses who tried every email client on the market and still could not get through the mail, follow the tasks in it, or tell what mattered from what did not. None of them kept after a task once the mail was read, so Gadfly was built to do exactly that, and it is the mail app its maker runs those businesses on.

Gmail and Google Workspace, Microsoft 365 and Outlook.com, iCloud, Fastmail, Yahoo, and any other IMAP account, including mail on your own domain. Add as many as you like; they share one inbox and one to-do list.

It reads the conversation. A date the mail states ("by Friday", an expiry, a renewal) wins, and Gadfly shows the sentence it came from. Otherwise it estimates from what is asked and who is waiting, and falls back to a default by importance. When a new message arrives, the deadline is read again. A date you set yourself is never changed.

Mac, Windows and Linux on the desktop; iPhone, iPad and Android on the go, with lock screen and home screen widgets. One Gadfly account syncs your to-dos, mailboxes and preferences across all of them.

Every account starts with 30 days of Pro free, no card needed. After that Gadfly Pro is €9 a month or €79 a year, with all your accounts and the AI included under fair use.

Yes. Gadfly is built by its founder with AI, and every feature request and bug report is read. When something you proposed ships, the first person who asked for it gets a month of Pro, up to twelve months a year.

Mail content is encrypted at rest with a key that belongs to your account only, and deleting the account deletes the key, so even old backups become unreadable. No ads, no data sales, no humans reading mail. We do not claim "only you can decrypt": the server has to read mail while it syncs, reads deadlines and chases you with the app closed.

No. Gadfly uses Anthropic's Claude through its commercial API, which does not train on the data sent to it. Claude only reads what it needs: new mail for triage, and to-dos for deadlines and summaries.

For now, yes: Gmail connects over IMAP with an app password, which takes about a minute and keeps Google out of the loop. Sign in with Google is coming. Microsoft accounts use the normal Microsoft sign-in.

Many people who lose track of mail they meant to answer use it for exactly that. Every to-do has a date, the pressure is visible at a glance by colour, and the app reaches out to you instead of waiting to be opened. It is a tool, not a treatment.

Yes. Gadfly supports passkeys (Face ID, Touch ID, Windows Hello, security keys) on the web, phone and desktop, plus password sign-in with an authenticator app code and backup codes.
