Speak Your Email, Get Professional Copy
You can dictate an email faster than you can type it. Most people speak at 150 words per minute. Most people type at 40 words per minute. That's 3x faster, minimum. But raw dictation sounds like speech, not professional writing.
Sonicribe's Mail Mode is specifically designed to transform spoken email drafts into polished, professional messages. You talk. Sonicribe formats. You paste. Done.
No subscription. No cloud upload. Just offline voice-to-email on your Mac, in 99+ languages, ready to paste directly into Gmail, Outlook, Apple Mail, or any email client.
How Mail Mode Works
Mail Mode takes your dictation and automatically structures it as a professional email. It does this using your custom output prompt—instructions that tell Sonicribe how to organize and format your spoken words.
Here's what happens in practice:
You speak: "Hey it's about the Q2 budget, we need to cut design spending by 15 percent, but keep the research team intact, I think we can do this if we postpone the redesign until Q3, let me know if that works for you, thanks" Mail Mode produces (using the right output prompt):Hi there,
I wanted to follow up on the Q2 budget planning. Looking at our current allocation, I'd like to propose a 15% reduction in design spending while keeping the research team at full capacity.
Here's what I'm thinking: We can postpone the redesign until Q3, which gives us the cuts we need without sacrificing critical research work. I believe this approach maintains our velocity while hitting the budget targets.
Let me know if this approach works for you, or if you'd like to discuss alternatives.
Best regards,
[Your Name]
That's the transformation Mail Mode handles. Your rambling voice memo becomes a structured, professional email—automatically.
The Output Prompt System
The exact email structure depends on your output prompt. This is the rule set you create that tells Sonicribe how to format your spoken words.
Here are four common email prompts you can customize:

Casual Business Email Prompt
Transform my spoken email into a casual but professional message with:
- Friendly greeting (e.g., "Hi Sarah,")
- Body: Organize my points into 2-3 short paragraphs
- Closing: Conversational sign-off (e.g., "Thanks," or "Best,")
Keep the tone warm and direct. Use short sentences.
Use this when emailing colleagues, team members, or clients you have a working relationship with.
Formal Business Email Prompt
Create a professional, formal email with:
- Proper greeting (e.g., "Dear Mr./Ms. [Name],")
- Subject line (extract from my first sentence)
- Opening: Brief context
- Body: Main points in numbered list or paragraphs
- Closing: Professional sign-off ("Best regards," or "Sincerely,")
Ensure formal tone, proper grammar, full sentences.
Use this for external stakeholders, formal proposals, or high-stakes communications.
Sales/Pitch Email Prompt
Format as a compelling email with:
- Engaging opening hook (related to their problem)
- Problem statement (what's challenging them)
- Solution (how I can help)
- Call to action (specific next step with deadline)
- Professional closing
Keep it concise. Aim for 150 words max.
Use this when reaching out to prospects or pitching opportunities.
Apology/Sensitive Email Prompt
Create a sincere, respectful email with:
- Genuine apology (no excuses)
- Acknowledgment of impact
- Explanation (brief, only if relevant)
- What I'll do differently
- Invitation to discuss
Ensure tone is humble and accountable throughout.
Use this when addressing mistakes or conflicts professionally.
Your Signature in the Output Prompt
One powerful feature of Mail Mode is the ability to embed your email signature in the output prompt itself.
Instead of manually adding your signature after Sonicribe formats the email, include it in the prompt:
Transform into a professional email with:
- Greeting
- Body: Organize my points logically
- Professional closing
- Signature:
Best regards,

Every email Sonicribe creates will automatically include your signature. No manual copy-paste required.
You can have multiple output prompts saved for different contexts (casual, formal, sales, etc.), each with its own signature. Switch between them in Sonicribe by selecting the prompt you need.
Before and After: Raw Dictation vs. Formatted Email
Let's look at a real-world comparison.
Raw Dictation (What You Actually Speak)
Hi um, I wanted to reach out about the redesign project, we've been working on it for like three months now, but I think we're going in the wrong direction, the user feedback has been pretty negative, especially around the navigation, also the performance is slower than the old version which doesn't make sense, I think we should probably hit pause, get the team together, review the feedback properly, and figure out if we should just go back to version three or if we can salvage this, let me know when you can meet about this, maybe next week?, thanks
This is how your brain works when speaking. Rambling, filler words, uncertain phrasing, poor structure. No email client is going to send this.
Mail Mode Output (With Proper Prompt)
Hi there,
I wanted to discuss the redesign project with you. After three months of development, we're receiving concerning user feedback, particularly around navigation and performance. The new version is actually slower than the previous iteration, which isn't what we intended.
I believe we should pause the project, convene the team to properly review the feedback, and decide whether to revert to version 3 or pivot the approach. I'd like to get your input before we move forward.

Same information. Dramatically different tone. Sonicribe handles this transformation in seconds.
Productivity Math: Speaking vs. Typing
Let's quantify this.
Typing an email:- Compose in your head: 2-3 minutes
- Type the email: 3-5 minutes
- Proofread and edit: 1-2 minutes
- Total: 6-10 minutes per email
- Dictate the email: 1-2 minutes
- Sonicribe formats: 5-10 seconds (automatic)
- Review and adjust if needed: 30-60 seconds
- Total: 2-3 minutes per email
If you send 10 emails per day, that's 30-70 minutes saved daily. Over a week, that's 2.5-6 hours. Over a year, that's 130-300 hours.
For busy professionals, this isn't just convenience—it's significant time recovery.
Tips for Better Email Dictation
To get the best results from Mail Mode, speak with intention.
Tip 1: Pause Between ThoughtsSonicribe uses silence to detect sentence and paragraph breaks. Pause naturally between ideas. This helps the output prompt organize your content into paragraphs, not one giant wall of text.
Tip 2: Speak As Though You're WritingYou don't have to sound formal, but try to speak more "written" than conversational. Avoid filler words like "um," "like," and "you know." Sonicribe handles some of these, but your prompt will work better with cleaner input.
Tip 3: Name Your Recipient at the StartIf the email is to "Sarah," begin with "Email to Sarah about the budget." This helps your prompt extract the greeting automatically.
Tip 4: State Your Ask ClearlyRead more: How to Use Whisper AI in 2026: Every Method Explained
Make your call to action explicit. "I need their response by Friday" is clearer than "let me know." Sonicribe's prompt can then format this into a proper CTA with a deadline.
Tip 5: Use Your Vocabulary PacksIf you're in a specialized field (tech, finance, law, medicine), enable the relevant vocabulary pack. Sonicribe will transcribe domain-specific terms accurately, so your formatted email uses the right terminology.
Works With Every Email Client
Mail Mode's real power is the auto-paste feature. Sonicribe can auto-paste directly into:
- Gmail (web)
- Outlook (web)
- Apple Mail
- Spark
- Hey
- ProtonMail
- Thunderbird
- And 23+ other email clients
You don't manually copy-paste. You dictate, Mail Mode formats, and Sonicribe automatically places the email in the compose field of your email client. You hit send.
This workflow is completely offline. No cloud. No third-party email integration. Sonicribe just formats the text and places it where you're typing.
Multiple Languages and Email Etiquette
Sonicribe supports 99+ languages. Mail Mode works in all of them.
If you write emails in Spanish, you can set your output prompt to:
Crea un correo profesional en español con:
- Saludo formal
- Cuerpo: puntos organizados lógicamente
- Cierre profesional
- Firma
Mantén un tono respetuoso y profesional.
Sonicribe will transcribe your Spanish dictation and format it according to Spanish business email conventions—formal greetings, proper closings, etc.
For international teams, this is significant. Your emails maintain appropriate tone and etiquette in the language you're using.
Customizing for Your Industry
Different industries have different email conventions.
Tech/Startup: Direct, casual, action-oriented Finance: Formal, detailed, documentation-focused Creative/Agency: Warm, conversational, relationship-building Legal: Precise, formal, reference-number-heavy Healthcare: Empathetic, clear, HIPAA-consciousCreate different output prompts for different contexts. Save them as favorites in Sonicribe. Switch between them based on who you're emailing.

One output prompt works for casual team emails. Another for investor updates. Another for client proposals. Same voice mode. Different formatting rules.
Integration With Your Writing Workflow
Mail Mode doesn't replace your writing—it augments it.
You still have full control over the final email. After Sonicribe formats your dictation, you can:
- Edit individual paragraphs
- Adjust tone
- Add details
- Delete sections
- Adjust the signature
Think of it as dictation that arrives pre-formatted. You get the time savings of speaking without sacrificing the polish of writing.
