Build a Free AI Voice Assistant in Minutes: Connect ElevenLabs to n8n for Hands-Free Email Automation
Tired of typing the same emails day after day? What if you could just speak your messages into existence? This guide shows how to create an AI assistant that listens to your voice commands, drafts perfect emails, and sends them automatically - saving you hours each week while making you look incredibly efficient.
What Is ElevenLabs and Why It's Revolutionary
Most business owners waste hours each week typing repetitive emails - client follow-ups, meeting confirmations, status updates. The blank email screen becomes a productivity black hole. ElevenLabs changes this by letting you speak naturally while AI handles the typing and sending.
ElevenLabs isn't just another text-to-speech tool. Their AI voices are indistinguishable from humans, with natural pauses, intonation, and emotion. The platform goes beyond simple voice generation to offer voice cloning, sound effects, and most importantly for automation - webhook integrations that connect to tools like n8n.
Key advantage: ElevenLabs' voice AI understands context, not just words. When you say "email Javed about the New York event", it knows to look up Javed's contact details, draft a professional message about the event specifics, and send it - all without explicit step-by-step instructions.
Setting Up Your AI Voice Agent
Creating your email-sending AI assistant begins in ElevenLabs' dashboard. You'll choose between three agent types: blank slate (fully customizable), personal assistant (pre-configured for tasks like scheduling), or business agent (industry-specific templates).
For maximum flexibility, we recommend starting with a blank agent named "Email Sender". The magic happens in the system prompt - this tells the AI how to interpret your voice commands. A well-crafted prompt makes the difference between an assistant that needs micromanaging and one that understands your business context.
Pro tip: Your system prompt should include examples of acceptable command formats ("Email [name] about [topic]"), your preferred email tone (professional, friendly, etc.), and any special instructions about contact lookup priorities or email formatting requirements.
Connecting ElevenLabs to n8n
The real automation begins when you connect ElevenLabs to n8n using webhooks. This bridge allows your spoken commands to trigger complex workflows in n8n without any manual intervention.
In ElevenLabs' tools section, you'll add a webhook tool configured to POST data to your n8n webhook URL. The critical configuration points are:
- Naming your webhook (e.g., "Email Assistant")
- Setting the method to POST
- Adding required properties (recipient name, email content)
- Testing the connection before finalizing
At 6:45 in the video tutorial, you'll see exactly how to configure the webhook properties to ensure n8n receives clean, structured data from your voice commands.
Automating Google Sheets Lookups
Your voice assistant needs to know where to find contact information. By connecting n8n to Google Sheets, you create a centralized contact database that your AI can query with simple voice commands.
The setup involves:
- Creating a Google Sheet with columns for name, email, phone, etc.
- Connecting n8n to the sheet using Google's API
- Configuring n8n to search the sheet based on the name from your voice command
- Handling cases where contacts aren't found (asking for clarification)
Time-saver: For teams, share this Google Sheet so everyone's contacts are available to the AI assistant. The system can even prioritize contacts based on department or recent interaction history when multiple matches exist.
Hands-Free Gmail Sending
The final piece connects n8n to Gmail, turning your drafted emails into sent messages. This isn't just basic email sending - the integration allows for:
- Dynamic subject lines based on email content
- Automatic signatures (with optional voice approval)
- CC/BCC management through voice commands ("also include Sarah")
- Scheduled sending if you specify a time in your command
At 10:30 in the video, you'll see how to configure the Gmail node in n8n to use the contact email from Sheets and the content generated from your voice command, creating a seamless flow from speech to sent email.
Real-World Testing: From Voice to Sent Email
Seeing is believing. In the tutorial's demonstration, a simple command - "Send an email to Javed about the upcoming tech event in New York" - triggers this sequence:
- ElevenLabs converts speech to structured data
- n8n finds Javed's email in Google Sheets
- AI drafts a professional email about tech events
- Gmail sends the message with proper formatting
- AI confirms completion verbally and via email
Real results: The entire process completes in under 15 seconds - faster than most people can type the first paragraph of an email. For businesses sending dozens of similar emails daily, this automation can save 2-3 hours per employee every week.

Frequently Asked Questions
Common questions about this topic
ElevenLabs is an AI voice generation platform that converts text to ultra-realistic speech. When connected to n8n through webhooks, it allows you to create voice-controlled automation workflows where you can speak commands that trigger actions like sending emails, updating spreadsheets, or other business tasks.
The integration works by having ElevenLabs send structured data from your voice commands to n8n, which then processes this data through your configured workflow to complete the requested actions.
- Converts natural speech to actionable data
- Uses webhooks to connect to n8n automation
- Supports multiple voice styles and languages
Yes, ElevenLabs and n8n allow complete customization. You can create different agent types (business, personal assistant) with specialized prompts for industries like finance, healthcare, or sales. The system prompt determines how your voice assistant behaves and what tasks it can perform.
For example, a real estate agent could create an assistant that understands property listings and client tour scheduling, while a doctor's assistant might be trained on medical terminology and appointment protocols.
- Create industry-specific voice agents
- Train on your business terminology
- Adjust formality and communication style
The workflow connects your voice commands through ElevenLabs to n8n, which then pulls contact information from Google Sheets, drafts the email content based on your spoken instructions, and sends it through Gmail - all without you typing a single word.
The system handles the entire process: contact lookup, email composition, proper formatting, and sending with your signature. You just speak naturally as if talking to a human assistant.
- Voice command → text conversion
- Contact lookup in Google Sheets
- Automatic email composition and sending
The only limits are your Google/Gmail account sending limits (typically 500 emails per day for free accounts) and ElevenLabs' free tier character limits. For high-volume sending, you would need to upgrade the ElevenLabs plan and potentially use a dedicated email service provider.
Most small businesses find the free tiers sufficient, while enterprises may need paid plans for higher volume. The system scales linearly - it's just as easy to send 5 emails as 50.
- Gmail limit: ~500 emails/day
- ElevenLabs free tier: 10,000 characters/month
- No limit on n8n workflow executions
Yes, ElevenLabs offers voice cloning functionality where you can upload samples of your voice and the AI will replicate it. This means your email recipients will hear your actual voice reading the email content if you enable text-to-speech in your emails.
The cloning process requires about 30 minutes of clear voice samples. Once trained, your AI assistant will speak in your voice when interacting with you and can even use your voice for outgoing voice messages or call responses.
- Requires ~30 minutes of voice samples
- Maintains your vocal characteristics
- Works for both assistant and outgoing messages
The same workflow can be adapted to update CRM records, create calendar events, send SMS messages, generate reports, or trigger any other n8n-supported actions. The only limit is your imagination and what APIs/services n8n can connect to.
Common extensions include: adding tasks to project management tools, logging customer interactions, processing orders, scheduling social media posts, or even controlling smart office devices - all through voice commands.
- CRM updates and data entry
- Calendar scheduling
- Cross-platform task automation
