WhatsApp has a 98% open rate.
Email gets 20%. SMS gets 15%. And every other marketing channel you are probably using right now sits somewhere in between.
Yet, most businesses make a huge mistake. They either ignore WhatsApp completely, or they spam their entire contact list with random messages. When you spam people, they get angry, and Meta bans your account.
The businesses that make money on WhatsApp don't spam. They follow a simple plan:
- They set up the right tools and get permission first.
- They grow their audience safely.
- They automate and scale.
If you skip step one, you will fail. This guide shows you the exact steps to build your WhatsApp marketing from scratch, the right way.
It will show how to do WhatsApp Marketing from scratch. By the end, you will have everything you need to go from zero to your first WhatsApp Marketing campaign - and a system to keep improving it.

Note: The free WhatsApp Business App can't do any of that. It's fine for 10 messages a day. The moment you want to broadcast beyond 256 people, add your team, or plug in automation, it breaks.
| Feature | WhatsApp Business App | WhatsApp API |
|---|---|---|
| Broadcast limit | 256 contacts | Unlimited |
| Multiple agents | ❌ | ✅ |
| Automation | ❌ | ✅ |
| AI agents | ❌ | ✅ |

Most WhatsApp API approvals happen instantly or within 10 minutes. Display name approval may take around 3 to 4 hours.
Once approved, your WhatsApp Business API status inside AiSensy will show LIVE.
Through a BSP, this is a guided form, not a developer project. On AiSensy, creating a WhatsApp Business API account takes about 10 minutes, and most accounts are live within 10 minutes to 24 hours.

Step 3: Get Facebook Verified/KYC Verified
Once your WhatsApp Business API is live, complete WhatsApp KYC Verification to unlock a higher messaging limit and verify your business faster.
Here's how to do it:
- Go to your AiSensy Dashboard and click Start KYC.
- Enter your GST number (or MSME number) and upload the required business document.
- Add the company director's Aadhaar details and verify using the OTP sent to the Aadhaar-linked mobile number.
- Review your information and submit the KYC request.
- Wait for the verification to be approved. Most KYC requests are processed within 1–2 hours.
Once approved, your daily WhatsApp broadcast limit increases from 250 to 2,000 users, allowing you to start reaching more customers immediately.

Step 4: Upload Contacts and Segment Them
Now you need to bring in your contacts. But don't just dump everyone into one big list and start blasting messages.
If you send the same message to everyone, people who don't find it relevant will block you or report you. That hurts your quality rating with Meta, which limits how many people you can reach.
Here's how to do it properly:
- Export your contacts from your CRM, your store, or a spreadsheet
- Format them as a CSV file with name, phone number (with country code), and any extra details like city or last purchase date
- Import them into AiSensy — there's no limit on how many you can upload
- As you import, add tags like "new customer," "cart abandoner," "Diwali buyer," "ad lead"
One important rule: only upload contacts who have agreed to receive messages from you. Uploading random lists or purchased contacts will get your number banned.
If your list is small right now, don't worry. Step 7 will show you how to grow it automatically.
Step 5: Create WhatsApp Templates and Get them Approved
Business-initiated messages need pre-approved templates. The workflow:
- Pick the right category: Marketing (offers, launches), Utility (order updates, reminders), or Authentication (OTPs). Miscategorized templates get rejected or recategorized at a higher price, so this choice matters.
- Write with variables: "Hi {{1}}, your order {{2}} has shipped."
- Add rich media and CTA buttons: Visit website, Call, Quick replies.
- Submit. On AiSensy, approvals typically clear in 10 minutes to 1 hour.
Approval hygiene: no all-caps, no walls of exclamation marks, no shortened URLs, and always an opt-out line ("Reply STOP") on marketing templates. If you'd rather not start from a blank page, the WhatsApp Template Library has proven formats to copy.
If you do not want to start from a blank page, you can use AiSensy’s WhatsApp Template Library for proven formats or try the AiSensy AI WhatsApp Template Generator to create Meta-ready WhatsApp templates faster.
Step 6: Create Ways for People to Find You on WhatsApp
This is the mindset shift that separates the 10% who profit from the 90% who don't: stop waiting for people to message you, and give them frictionless reasons to.
- Click-to-WhatsApp Ads (CTWA): Meta ads with a "Send Message" CTA. The old path (ad → landing page → form → callback) converts at 1-3%. Ad → instant WhatsApp conversation? Drop-off nearly disappears, and you capture name and number the second they click.
- With AiSensy's built-in Meta Ads Manager, you run and track these from the same dashboard. Best for: D2C, EdTech, real estate, financial services.
- QR codes: store entrance, billing counter, packaging, event booths. Scan → pre-filled greeting → captured. Best for: retail, restaurants, showrooms, clinics.
- Website widget: a "Chat with us" bubble via the WhatsApp button generator. Your pricing-page visitors are the warmest leads you have.
- WhatsApp links: a wa.me link in your Instagram bio, email signature, and invoices.

Step 7: Send Your First Broadcast (Segmented, Tested, Timed)
You're set up. Now it's time to send your first campaign. Before you hit send, go through these tips:
- Pick a specific segment, not your full list. Send only to people for whom this message is relevant.
- Use a template with an image or video. Visual messages tend to get more clicks than plain text.
- Personalise it. Add the customer's name, their city, or the last product they looked at.
- Watch your send time. Most audiences respond best in a morning window (roughly 9–11 AM) and an evening window (roughly 6–9 PM). Very late sends, after 10–11 PM, tend to underperform. Exact timing varies by audience, so treat this as a starting point and test what works for yours.
- Test with a small batch first. Send to a few hundred contacts, check that links work and the message reads well, before it goes out to thousands.
- Send, then watch delivery and read rates as they come in.

Step 8: Track, Retarget, Scale (The Step That Never Ends)
What you want: compounding results, not one good campaign.
Track weekly: delivery rate, read rate, click-through rate, reply rate, conversion rate, and cost per lead on CTWA ads.
Diagnose drops fast:
- Low reads → test copy and send timing
- Low clicks → change the CTA or add richer media
- High opt-outs → too frequent, or wrong segment
- Low ad conversions → fix the welcome flow after the click
Then retarget, because most customers don't convert on first touch. They browse, ask, and drop off. Segment by behavior (read but didn't click, clicked but didn't buy) and follow up with a sharper offer. Retargeting campaigns consistently outperform first-touch broadcasts because the intent is already proven.
As your quality rating holds, Meta raises your messaging tier, up to unlimited. That's the scale loop: better targeting → better engagement → higher limits → more reach.
Optional Step: Apply for Blue Tick
Once your WhatsApp Business API account is live, you can also apply for the WhatsApp Blue Tick, earlier known as the Green Tick.
The Blue Tick is WhatsApp’s official verification badge. It appears next to your business name and helps customers trust that they are talking to a genuine brand.
With AiSensy, you can apply for Blue Tick verification for free.
To improve your chances, make sure you have:
- Active WhatsApp Business API account
- Completed Meta Business Verification or KYC
- Approved WhatsApp display name
- 2-step verification enabled
- Registered business, not an individual account
- Good quality WhatsApp Business Account
- Tier 2 or higher messaging level
- At least 5 organic PR or news articles about your brand
- A notable and trustworthy business presence online
The Blue Tick is optional, but it can help improve trust, reduce customer doubt, and make your WhatsApp campaigns look more credible.

Optional: Set Up Automation with WhatsApp AI Agents
Once your WhatsApp conversations start increasing, you do not need to reply to every customer manually.
With AiSensy’s WhatsApp AI Agent, you can automate sales, support, lead qualification, FAQs, order updates, demo booking, and customer routing, without writing code.
With WhatsApp AI Agent you can:
- Answer customer questions using your website, FAQs, PDFs, catalogues, and policies

- Route users to the right chatbot flow Hand over complex chats to your team when needed
To set it up, train the AI Agent with your business data through the Knowledge Base, define its tone and rules using the AI Orchestrator, connect tools through Tool Calling, and use AI Routing if you have multiple flows.
This helps your business stay active on WhatsApp 24/7, reduce manual work, and convert more conversations automatically.

FAQs
Sign up with a Meta-authorized BSP like AiSensy, get your WhatsApp Business API access, and clear Meta Business verification. From there, set up your profile, upload your opted-in contacts, get your templates approved, build opt-in entry points, automate with an AI Agent, and launch segmented broadcasts. With AiSensy, most of this happens inside one dashboard, no developer needed, and businesses typically go live within 10 minutes to 24 hours.
No. BSP platforms like AiSensy are fully no-code. Broadcasts, chatbot flows, AI agents, ads, and analytics all run from one visual dashboard.
With AiSensy, most accounts are approved within 10 minutes to 24 hours, depending on business verification and display name review.
Your legal business name plus one proof document: GST certificate, certificate of incorporation, utility bill, or bank statement. The name on documents must exactly match your Business Manager details, since mismatches are the top rejection reason.
New API accounts start at 1,000 business-initiated conversations per 24 hours. With consistent quality, Meta upgrades you to 10,000, then 100,000, then unlimited.
Two costs: your platform subscription and Meta's per-template charges. In India, this is roughly ₹1.09 per marketing message and ₹0.145 per utility message. AiSensy plans start at ₹1,500/month with unlimited users, and Meta's charges pass through at cost.
No. Meta requires explicit opt-in consent. Messaging scraped or purchased lists gets your number flagged and banned, which is why opt-in entry points matter.
The API is better for WhatsApp marketing at scale. The WhatsApp Business App caps broadcasts at 256 contacts with no automation, no multi-agent access, and no ads integration. The API removes those limits.
