Best Practices & Tips

Apple Mail is the default email client for millions of Mac users, and Echoo makes it smarter without requiring any plugins or extensions. Every text transformation shortcut works directly in the compose window, letting you draft and polish emails without leaving Mail.

The most common workflow is drafting a quick reply and polishing it before sending. Type your response naturally without worrying about tone or grammar, select the text, and press your Professional Tone shortcut. The AI transforms your casual draft into a polished message in seconds. For different email contexts, switch between Professional Tone for client and executive emails, and Casual Tone for team and friendly messages.

Apple Mail's rich text formatting is preserved when Echoo transforms your text. Bold, italic, font choices, and colors all remain intact. The AI changes the words while Apple Mail maintains the visual formatting. This means you can apply your formatting first, then polish the text without redoing any styling work.

Create email-specific commands that handle common Apple Mail scenarios. A "Quick Reply" command should produce a brief, professional response from a rough draft. A "Decline Politely" command should help you say no graciously when turning down meetings, requests, or opportunities. A "Follow Up" command should generate a polite follow-up from a brief description of what you are waiting for.

For users who handle high volumes of email, Echoo dramatically reduces response time. Instead of carefully crafting each reply, type a quick stream-of-consciousness response, select it, polish with one shortcut, and send. This approach can cut email writing time by half or more while improving the quality of your responses.

Google Gemini offers fast, high-quality email polishing on its free tier, making it ideal for Apple Mail users who process many emails daily. OpenAI models are also fast and produce excellent business email prose. For emails containing sensitive or confidential information, use Ollama with a local model so your email content stays on your Mac.

Pro Tips

Apply text formatting (bold, italic, fonts) in Apple Mail first, then use Echoo to polish the words. Your formatting is preserved through the AI transformation.

Create a "Decline Politely" command for graciously turning down meeting requests, project invitations, or proposals that come through email.

Use the Casual Tone shortcut for internal team replies and Professional Tone for external or executive emails, switching between them based on the recipient.
