For people who want Spark’s best ideas without a company’s server between them and their mailbox. MailTiger talks directly to Gmail, Outlook, iCloud and any IMAP server. Everything you do happens on your device first and is written down before it reaches the server, so the app never waits on the network.
MailTiger 0.1.0 isn’t released yet. The engine, reading, search and sending are built; Smart Inbox, notifications, AI and the release work are still ahead.
What it does
Gmail and Google Workspace, Outlook and Microsoft 365 with their own sign-in, plus iCloud, Yahoo, Fastmail and any IMAP server, with the settings found for you.
Reading, search, archive and moving around use a database on your device. Actions queue offline and replay exactly once, even after a crash.
from:, has:attachment, newer_than: and the rest, across every account, with saved searches. About 5 ms across 100,000 messages in the engine benchmark.
Undo Send, an Outbox that shows where every message is, Send Later, and drafts that save themselves and continue on your other devices. An interrupted send is never resent on its own.
Remote images stay blocked until you allow them, and known tracking pixels are stripped even then. Mail never runs scripts, and MailTiger will never add read-receipt pixels.
Smart Inbox sorted on your device, snooze, a gatekeeper for new senders, notifications, widgets, a command palette and private on-device AI. Planned, not in the app yet.
How it works
Install MailTiger on your Mac, iPhone or iPad, and sign in with Google or Microsoft or add any IMAP account.
Your newest mail arrives first, and the rest syncs behind it into a database on your device.
Start a 14-day trial with your email and no card. One license then covers five of your devices.
