In the previous article, we explained what agentic AI is. Now lets actually build one — a real, working AI agent that handles a repetitive task in your business, starting today.
We are going to use Lindy — the no-code agentic AI platform — because it requires zero coding, connects to the tools you already use, and has a free tier generous enough to get your first agent running without spending anything.
By the end of this guide you will have a live AI agent managing a real workflow in your business. Total cost: $0 to start, $20-$49/month when ready to scale.
If you have not read Part 1 yet, start with What is Agentic AI? — it explains the core concepts this guide builds on.
What We Mean by "AI Employee"
An AI employee is not a chatbot that answers questions. It is an agent that holds a specific job in your business — with defined responsibilities, tools it can use, and tasks it completes without you supervising each step.
— Think of it like this
Traditional VA
Costs R8,000-R15,000/month
Works 8 hours/day
Needs breaks, sick days
Learns slowly
AI Employee
Costs $20-$49/month (~R360-R880)
Works 24/7/365
Never gets tired or sick
Improves as you train it
Obviously a human VA brings things an AI cannot — creativity, emotional intelligence, complex problem solving. But for the repetitive, rule-based work that eats your time? An AI employee wins on every metric.

Step-by-Step: Build Your Inbox Manager in 60 Minutes
We are going to build the Inbox Manager — the easiest first agent and the one with immediate, visible impact. Here is exactly how to do it:
Create your free Lindy account
⏱ 5 minGo to lindy.ai and sign up with your Google account. The free tier gives you enough to build and run your first agent without entering a credit card.
Use the same Google account connected to your primary business Gmail. This makes the integration seamless in the next step.
Connect Gmail
⏱ 3 minIn your Lindy dashboard, go to Integrations and connect your Gmail account. Lindy will ask for permission to read, label, and draft emails on your behalf. Grant all permissions — without these, your agent can only observe, not act.
Lindy uses OAuth — it never sees or stores your password. Your data stays in Google's infrastructure. If you are concerned about sensitive emails, you can limit access to specific labels only.
Create a new Lindy (your agent)
⏱ 5 minClick + New Lindy and choose Start from scratch. Give it a name like "Inbox Manager" or "Email Assistant." This is your agent's identity inside the system.
Write your agent's instructions
⏱ 15 minThis is the most important step. Paste the following prompt into the instructions field, then customise the parts in brackets for your specific business:
— Copy this prompt into Lindy
You are my Inbox Manager. Your job is to help me process emails efficiently. When a new email arrives, do the following: 1. CATEGORISE it: URGENT / CLIENT / INVOICE / NEWSLETTER / ADMIN / SPAM 2. DRAFT a reply for CLIENT or URGENT emails. Keep it professional, warm, under 100 words. Sign off as [YOUR NAME] from [YOUR COMPANY]. 3. Every day at 8am, send me a DIGEST to [YOUR EMAIL] summarising: - Number of emails received - Any URGENT items needing attention - One-line summary of each CLIENT email My business is [BRIEF DESCRIPTION]. My tone is [professional / friendly / formal]. Never send a reply without my approval — only draft it.
The last line is critical for safety — Never send a reply without my approval. Keep this in until you have tested the agent for at least 2 weeks and trust its output consistently.
Set your triggers
⏱ 5 minIn Lindy's workflow builder, set two triggers:
Test with 10 real emails
⏱ 10 minBefore activating your agent fully, run it against 10 real emails from your inbox. Check that the categorisation is accurate and the drafted replies sound like you. Tweak your instructions prompt if needed — most people do 2-3 iterations. This is normal. The prompt is your agent's training manual.
Activate and monitor
⏱ OngoingTurn your Lindy on. For the first week, review every draft reply before anything goes out. After 7 days you will have a clear picture of where the agent excels. After 2 weeks of consistent good performance, you can selectively enable auto-send for low-stakes categories.
What to Do After Week 1
Once your Inbox Manager is running reliably, here is how to expand your AI team systematically:
Add a second agent
Build the Follow-Up Agent for invoices. Connect it to the same Gmail. Your two agents now work as a team — the Inbox Manager categorises, the Follow-Up Agent handles collections.
Connect your CRM
Integrate Lindy with Notion or HubSpot. When the Inbox Manager identifies a CLIENT email, it can automatically create or update a contact record without you touching anything.
Add GoHighLevel
GoHighLevel is the most powerful CRM + automation platform for agencies and SMBs. Your Lindy agents can feed data directly into GHL pipelines, automating your entire sales follow-up sequence.
The Honest Truth About AI Employees
Building your first agent is exciting — but here is what to expect in the first month:
Week 1 will feel rough. Your agent will misclassify some emails, draft replies that are slightly off-tone, and need constant tweaking. This is normal. Stick with it.
Week 2 gets better. As you refine the prompt and correct mistakes, the agent learns your patterns. By Day 14, most people are genuinely impressed.
Month 2 is where it compounds. You stop thinking about email management. It just happens. That mental bandwidth goes somewhere better — like client work.

Frequently Asked Questions
How long does it take to set up the first agent? +
Most people get their Inbox Manager running in 45-90 minutes on their first attempt. The setup itself is quick — the time goes into writing good instructions and testing against real emails.
Will the agent ever send emails without my permission? +
Not unless you explicitly enable auto-send. By default, Lindy only drafts replies — you approve and send each one. We strongly recommend keeping it this way for at least the first two weeks.
What if my business email is not Gmail? +
Lindy also integrates with Outlook/Microsoft 365. The setup process is identical — just connect your Microsoft account instead of Google in Step 2.
Can I build these agents in GoHighLevel directly? +
Yes — GoHighLevel has its own AI workflow builder and is more powerful for sales and CRM automation specifically. For general task automation across multiple apps, Lindy is more flexible as a starting point.
Is this suitable for a one-person business in South Africa? +
Absolutely — this guide was written with exactly that in mind. The $20/month cost translates to roughly R360/month. If your agent saves you even 3 hours of admin per month, you have already paid for it many times over.
