Polish Business Emails in One Keystroke on Mac

The Email You Meant to Send vs. the One You Actually Wrote

You've been there. It's 4 PM, you're juggling three threads, and you fire off a quick follow-up to your team. You hit send, then re-read it: "seriously, get back to me ASAP" — did you really just write that to your manager's skip-level?

Rushed emails are a universal problem. The intent is fine, but the tone lands wrong. Too casual, too blunt, or just rough enough to make someone pause. You don't need a writing coach — you need a way to smooth the edges before you hit send.

That's exactly what an email tone polisher does. And with WunderType, you can build one that works in any app on your Mac — Mail, Outlook, Gmail in the browser, Slack, wherever you type.

How WunderType Polishes Your Email Tone

WunderType is a macOS menu bar app that transforms selected text using AI. You create a Custom Prompt — a reusable text action with its own name, instruction, and keyboard shortcut. For email polishing, you'd set up a prompt called "Polished Email Draft" that refines tone, fixes grammar, and rephrases casual language into something appropriate for business communication.

Once it's set up, the workflow is dead simple: select your draft text, press your shortcut, and your email is rewritten in place. No copying to another app, no browser extensions, no context switching.

See It in Action

Here's a real example. Say you've just typed this follow-up to your team:

Before

Hey team,
Just wanted to quickly follow up on that proposal. It’s kinda urgent, ya know? Let me know if you have any questions, but seriously, get back to me ASAP.
Thanks,
Mark
(P.S. – attached is the doc!)

Select the text, press ⌥⇧⌘E, and WunderType transforms it to:

After

Subject: Follow Up: Proposal - [Proposal Name]

Dear Team,

I am following up on the recently submitted proposal. Your prompt review and feedback are greatly appreciated. Please do not hesitate to contact me with any questions. Thank you for your attention to this matter.

Sincerely,
Mark

Same message, same intent — but now it reads like someone who has their act together. The casual filler is gone, the tone is respectful, and it's structured properly with a clear subject line. That's the difference between an email people skim and one they actually respond to.

Does It Work With Professional Email Apps?

Yes — and that's the point. WunderType works system-wide through the macOS Accessibility API. It doesn't care whether you're composing in Apple Mail, Outlook, a Gmail browser tab, or even a Slack DM. If you can select text, WunderType can polish it. No plugins to install per app, no browser extension to maintain.

Set It Up in 30 Seconds

1. Click the WunderType icon in your menu bar and open Custom Prompts
2. Create a new prompt named "Polished Email Draft" with this instruction: Refine the tone to be more professional and courteous. Rephrase casual language, correct grammar, and ensure the message is clear and appropriate for business communication.
3. Assign a keyboard shortcut — now it works in any app on your Mac

That's it. Every email, every message, every Slack reply — one shortcut to go from rough draft to polished professional tone.

Better Emails, Less Overthinking

Most people don't write bad emails because they're bad communicators. They write rough emails because they're busy. An email tone polisher doesn't change what you want to say — it changes how it lands. And when every message you send reads clearly and professionally, people take you more seriously.
