Partnership proposal for Q2 video

Sarah Chen <sarah@acmebrand.com> · 2 minutes ago
Hi Dave,

We'd love to sponsor a dedicated video on your channel in Q2. Our budget is $3,500 for a 60-second integration with a unique tracking link.

Would you be open to discussing this further? Happy to jump on a call this week.

Best,
Sarah
Features

Email that works for you

🔬

AI Triage

Incoming mail is classified automatically. Sponsors, notifications, marketing, money — sorted before you open your inbox. Hardcoded rules handle the obvious; AI handles the rest.

✎

Smart Drafts

AI drafts replies in your voice, using your writing style and past corrections. It learns how you actually communicate — not how a chatbot would.

🔒

Private by Design

Your email lives on your Mac. AI features are opt-in with clear consent. Use local models via Ollama and your data never leaves your device.

⚡

Native Performance

Built in SwiftUI for macOS. No Electron wrapper, no web views for UI. Instant launch, low memory, smooth scrolling. Your Mac, respected.

📧

Multi-Account

Gmail, iCloud, Outlook, Fastmail — any IMAP provider. All your accounts in one unified inbox with proper thread isolation.

⌨

Keyboard First

Gmail-style shortcuts built in. Archive with e, star with s, navigate without the mouse.

How it works

Three steps to inbox zero

1

Connect your accounts

Sign in with Gmail OAuth or add any IMAP provider. Multi-account from day one.

2

AI learns your inbox

Triage rules classify your mail. AI observes your corrections and adapts its drafts to match your voice.

3

Focus on what matters

Sponsors and replies surface first. Marketing and notifications are filed away. You see only what needs your attention.
