How to Automate Email Replies with an AI Agent (No Coding Required)

If you are like most people, email is eating your day alive. Studies consistently show that the average professional spends between 1 and 2 hours every single day just reading and responding to emails. That is roughly 500 hours per year - more than 12 full work weeks - spent typing replies, acknowledging meeting invites, and answering questions you have answered a hundred times before.

What if your computer could handle most of that for you?

With an AI desktop agent, it can. You do not need to write any code. You do not need any technical background. You just tell your computer what to do with your emails, and it does it - opening your inbox, reading messages, drafting replies, and sending them (with your approval, of course).

This tutorial will walk you through the entire process from scratch.

What You Will Need

Before we get started, here is what you need:

• A Mac computer running macOS 13 (Ventura) or later
• An email account - Gmail, Outlook, Apple Mail, or any web-based email
• Fazm - a free, open-source AI desktop agent (we will install it together below)
• About 10 minutes to set everything up

That is it. No coding tools, no terminal commands, no technical knowledge required.

Why Email Is Perfect for AI Automation

Not every task is a great fit for AI automation, but email is one of the best. Here is why:

Most replies follow patterns. Think about your inbox. How many emails require a truly unique, thoughtful response? Probably fewer than you think. A large chunk of your replies fall into predictable categories - confirming meetings, answering FAQs, acknowledging receipts, forwarding requests to the right person, or saying "thanks, got it."

The cost of mistakes is low. Unlike, say, deleting files or making purchases, a slightly imperfect email reply rarely causes serious problems. And as you will see, you always get to review before anything gets sent.

The time savings compound. Automating email does not just save you the minutes spent typing. It also saves the mental energy of context-switching in and out of your inbox all day long.

Step 1: Install Fazm

First, let's get the AI agent installed on your Mac. This takes about 2 minutes.

1. Open your web browser and go to fazm.ai
2. Click the Download button on the homepage
3. Once the file downloads, open it - it will be in your Downloads folder
4. Drag the Fazm icon into your Applications folder when prompted
5. Open Fazm from your Applications folder (or use Spotlight - press Command + Space and type "Fazm")

When you first open Fazm, your Mac might show a security warning saying the app was downloaded from the internet. Click Open to proceed - this is normal for any app downloaded outside the Mac App Store.

Fazm will ask for a few permissions:

• Accessibility access - this lets Fazm click buttons and type text in other apps
• Screen recording - this lets Fazm see what is on your screen so it knows where to click

Grant both permissions when prompted. These are the same permissions that screen sharing and accessibility tools use. Without them, Fazm cannot interact with your other apps.

Once installed, you will see a small floating toolbar on your screen. That is Fazm, ready to go.

Step 2: Activate Push-to-Talk

Fazm uses voice commands by default, which makes it feel very natural - like talking to an assistant sitting next to you.

Here is how push-to-talk works:

1. Press and hold the designated hotkey (by default, it is the right Option key on your keyboard)
2. Speak your command while holding the key
3. Release the key when you are done speaking

That is all there is to it. Fazm will hear your command, understand what you want, and start working.

You can also type commands if you prefer. Click on the Fazm toolbar and type your instruction in the text box. Both methods work equally well.

Step 3: Automate Your First Email Reply

Now for the exciting part. Let's automate some email replies.

Replying to a Single Email

Start simple. Open your email in a browser (Gmail, Outlook, whatever you use), then activate Fazm and say:

"Reply to the latest email from Sarah saying I will be at the meeting at 3pm"

Here is what happens behind the scenes:

1. Fazm looks at your screen and identifies your email inbox
2. It finds the latest email from Sarah
3. It opens that email
4. It clicks the Reply button
5. It types a natural-sounding response confirming the 3pm meeting
6. It pauses and shows you the draft before sending

You will see everything happening on your screen in real time. The mouse moves, buttons get clicked, text gets typed - just as if someone were sitting at your computer doing it for you.

Replying to All Unread Emails

Ready to go bigger? Try this:

"Go through my unread emails and draft replies to each one"

Fazm will work through your inbox one by one, reading each unread message and drafting an appropriate reply. For straightforward emails (meeting confirmations, simple questions, acknowledgments), it will draft a reply on the spot. For complex emails that need your specific input, it will flag them and move on.

Batch Processing with Specific Instructions

You can get more specific about how you want replies handled:

"Reply to all emails from today. For meeting invites, accept them. For questions about the project deadline, say it is March 28th. For everything else, just acknowledge receipt."

The more context you give, the better the replies will be.

Step 4: Review Before Sending

This is the most important step, and it is built right into the process.

Fazm always pauses before sending an email. It drafts the reply and then waits for you to review it. You will see the draft on screen, and you can:

• Approve it by saying "send it" or clicking the send button yourself
• Ask for changes by saying something like "make it more formal" or "add that I will bring the report"
• Skip it by saying "skip this one" and moving to the next email

This review step is critical. AI agents are very good at drafting replies, but they do not know everything about your relationships, your tone preferences, or sensitive context that might affect how you respond. Always take a few seconds to scan the draft.

Over time, you will find that most drafts need little or no editing. But that safety net of reviewing before sending means you never have to worry about an embarrassing or incorrect email going out.

Tips for Getting Better Email Replies

After using email automation for a few days, here are some tips that will make the experience even better:

1. Be Specific About Your Tone

Instead of just saying "reply to this email," try:

• "Reply warmly and thank them for the update"
• "Reply briefly and professionally"
• "Reply casually - this is a friend, not a coworker"

The AI agent picks up on tone cues and adjusts the writing style accordingly.

2. Give Context the Agent Cannot See

Sometimes an email references something from a phone call or an in-person conversation. The agent does not know about those, so fill in the gaps:

"Reply to Mike's email about the budget. Tell him we discussed this on Monday and agreed to increase it by 15 percent."

3. Set Up Common Reply Templates in Your Head

Think about the types of emails you get most often and develop go-to phrasings for them:

• For meeting requests: "Accept and say I look forward to it"
• For vendor pitches: "Reply politely declining, saying we are not looking for new tools right now"
• For status update requests: "Reply with a brief update that the project is on track for next Friday"

The more consistently you phrase these, the faster the whole process becomes.

4. Start with Low-Stakes Emails

When you are first getting comfortable, practice with emails where a slightly imperfect reply will not matter much. Internal team acknowledgments, newsletter replies, scheduling confirmations - these are all great starting points.

Save important client communications or sensitive topics for when you have built up confidence in the tool.

5. Use It Alongside Your Existing Workflow

You do not have to go all-in on day one. Many people start by using the agent for their morning email sweep - processing all the emails that came in overnight - and then handle the rest of the day manually. Over time, they gradually expand what they delegate.

Beyond Basic Replies: What Else Can You Automate?

Once you are comfortable with basic reply automation, here are some more advanced email tasks to try:

Sorting and labeling: "Go through my inbox and label all emails from clients as 'Client' and all newsletters as 'Read Later'"

Forwarding with context: "Forward the budget spreadsheet from Lisa's email to the whole finance team with a note saying please review by Friday"

Calendar integration: "Check my emails for any meeting requests and add them to my calendar" - for more on this, see our guide on AI calendar and inbox automation

Follow-up reminders: "Flag any emails I have not responded to in 3 or more days"

Composing new emails: "Write an email to the team summarizing yesterday's meeting notes and send it"

Common Questions

Will the AI agent read my private emails?

The agent only sees what is on your screen at the time you give it a command. It does not have background access to your email account. It works by looking at what you can see and interacting with it, the same way a person sitting next to you would.

What if it sends an email I did not approve?

Fazm is designed to pause before sending. You always get a chance to review. If you are extra cautious, you can set your email to have a short send delay (Gmail has an "Undo Send" window of up to 30 seconds) as an additional safety net.

Does it work with my email provider?

If you can open your email in a web browser on your Mac, Fazm can work with it. Gmail, Outlook, Yahoo Mail, iCloud Mail, Fastmail, ProtonMail - they all work because the agent interacts with whatever is on your screen.

Can it handle attachments?

Yes. You can say things like "reply and attach the Q1 report from my Documents folder" and the agent will find the file, attach it, and include it in the reply.

What about emails in other languages?

Fazm supports multiple languages. You can read emails in one language and reply in another, or keep everything in the original language. Just specify what you want: "Reply in Spanish" or "Reply in the same language as the original email."

Getting Started Today

The best way to learn is to try it. Here is a simple challenge: the next time you sit down to process your inbox, install Fazm and use it to reply to just 5 emails. Time how long it takes compared to doing it manually.

Most people find that those 5 emails take about 2 minutes with an AI agent versus 10 to 15 minutes doing it by hand. Multiply that across an entire inbox, and you are looking at saving an hour or more every single day.

That is an hour you could spend on actual work, on creative projects, on learning something new, or just on stepping away from your screen and taking a break. Your inbox will always fill back up. Your time will not.
