How to Dictate Emails on Mac
3 Ways That Actually Work (2026)

Typing emails is slow. Speaking is 3–4x faster. Your Mac already has two built-in options for dictating emails, and there's a third that solves the problems both of them have. This guide covers all three across Gmail, Outlook, and Apple Mail.

Option 1: Apple Dictation

Every Mac includes built-in dictation that works in any email app's compose field — Gmail in Chrome, Outlook, Apple Mail, or anything else.

Setup

  1. Open System Settings > Keyboard > Dictation and toggle it on.
  2. Open your email app and click Compose or Reply.
  3. Click into the message body.
  4. Press fn twice and speak.
  5. Press fn again to stop.

Where it falls short

  • 30–60 second timeout — for anything longer than a quick reply, you restart it repeatedly.
  • Manual punctuation — you say “comma,” “period,” “new line” out loud. This breaks the flow of composing an email.
  • Filler words stay — every “um” and “so basically” goes into the email.
  • No tone awareness — the same raw transcription whether you're writing to a client or replying to a friend.

Option 2: Siri

Siri can send simple emails hands-free. Say “Hey Siri, send an email to [contact name]” and Siri will ask for a subject and body.

Where it falls short

  • Apple Mail only — Siri can't compose in Gmail or Outlook.
  • Short messages only — anything beyond a few sentences becomes impractical.
  • No editing — you can't review or edit before sending through Siri alone.
  • Internet required — Siri always needs a connection.

Option 3: Resonant — system-wide dictation for email

Resonant works in every email app on your Mac. Click into the compose field, press fn, speak your email, release the key. Clean, punctuated text appears — ready to send.

What it's good at

  • No time limit — dictate a full email in one session.
  • Automatic punctuation — no saying “comma” or “period.”
  • Filler word removal — “um” and false starts cleaned.
  • Context-aware tone — adapts formatting for email.
  • Fully offline — draft emails on a plane.
  • Any email app — Gmail, Outlook, Apple Mail, Superhuman, HEY, Fastmail.

Setup

  1. Download Resonant and move it to Applications.
  2. Grant Microphone and Accessibility permissions.
  3. Open your email app and click into a compose field.
  4. Press fn and speak.
  5. Release. Punctuated text appears.

Which one should you use?

For a quick one-sentence reply: Apple Dictation. Press fn twice and go.

For a hands-free simple email: Siri — if you use Apple Mail and the email is short.

For anything longer than a paragraph, across any email app: Resonant. No timeout, automatic punctuation, filler removal, and it works in Gmail, Outlook, and everything else.

Frequently asked questions

Can I dictate emails in Gmail on Mac?

Yes. Apple Dictation (fn twice) works in Gmail's compose window. Resonant also works — just press fn and speak.

Does dictation work in Outlook on Mac?

Yes. Apple Dictation works in Outlook's compose field. Outlook also has its own Dictate button with Microsoft 365. Resonant works in both the app and Outlook web.

Why does dictation stop after one sentence?

Apple Dictation has a 30–60 second timeout. For longer emails, you restart it repeatedly. Resonant has no time limit.

Can I dictate emails offline?

Apple Dictation partially works offline for short sessions. Siri requires internet. Resonant works fully offline — draft emails on a plane and send when you're back online.

How do I add punctuation when dictating?

With Apple Dictation, say “comma,” “period,” “new line” out loud. With Resonant, punctuation is added automatically.

What Resonant offers beyond dictation

Resonant isn't just a faster way to type. It's a voice workspace with capabilities no other dictation tool provides.

MCP server for AI tools

Resonant exposes 11 MCP tools that let any AI agent — Claude, Codex, and more — query your entire voice workspace — meetings, dictations, memos, ambient context, and daily journal. Your AI assistant knows what you said this morning. Learn more

Meeting transcription with speaker labels

Dual-channel recording — your mic and system audio on separate channels. NVIDIA Sortformer diarization identifies who said what. No bot joins the call. No audio leaves your Mac. Learn more

Ambient context capture

Passively records which apps you use, window titles, URLs, and dwell time — all locally. This makes dictation context-aware and gives your AI tools a queryable work timeline. Learn more

Two on-device speech models

NVIDIA Parakeet TDT v3 (0.6B, 25 languages) and Qwen3 ASR (0.6B, 30+ languages), both compiled to CoreML and running on Apple Neural Engine. Under 4% WER on English benchmarks. Learn more

Cloud cleanup with hallucination detection

Optional AI post-processing fixes STT errors and adapts to context (email, message, code). Guardrails detect when the LLM rewrites your meaning instead of cleaning your grammar. Learn more
