WhatsApp Marketing for Small Businesses
Earn permission, send something useful and be ready to answer when people reply.
WhatsApp marketing is not a contact-list blast. It starts when a customer asks to hear from you and continues as a conversation. The steps below cover the profile, opt-in, broadcast and follow-up work that makes that possible.
Step 1: Set up the account
Your foundation is a proper WhatsApp Business account (free).
- Download WhatsApp Business from the App Store or Google Play
- Register with your business number
- Go to Settings → Business tools → Business profile
- Fill in everything: business name, category, description, address, hours, website, and email
- Add a logo as your profile photo
A complete profile lets customers check your hours, location and business details before they message.
Step 2: Build a catalog if you sell products
WhatsApp Business lets you showcase products right inside the app.
- Business tools → Catalog
- Tap Add item
- Add photos, name, price, description, and a link
- Repeat for your range
You can now share a product directly in a chat instead of describing it from scratch.
Step 3: Build an opt-in audience
This is the step that separates marketing from spam. Only message people who agreed to hear from you. Here's how to grow that list legitimately:
- Click-to-WhatsApp links/buttons on your website, Instagram bio, and Google Business profile. Use a
wa.me/yournumberlink so people start the conversation. - QR codes in-store, on receipts, or on packaging that open a chat.
- Checkbox at checkout or booking: "Send me updates and offers on WhatsApp."
- Ask in conversation: when someone messages you, it's fine to ask "Want me to message you when we have openings/offers?"
The golden rule: the customer initiates or explicitly opts in. That keeps you compliant with WhatsApp's Business Policy and keeps your number safe.
Step 4: Use broadcast lists only for opted-in contacts
For sending an update to many opted-in contacts at once, use Broadcast Lists (not by adding strangers — only people who opted in and have your number saved).
- In WhatsApp, tap ⋮ → New broadcast (or Broadcast Lists)
- Select the opted-in contacts
- Compose your message and send
Each recipient gets it as an individual message, not a group. Important: recipients only receive a broadcast if they have your number saved in their contacts — another reason opt-in matters.
Step 5: Write a message worth opening
Whatever you send, follow these principles:
- Lead with value, not a pitch. "Here's a tip / heads up / early access," not "BUY NOW."
- Personalize. Use the person's name and reference why they're hearing from you.
- Keep it short. Two or three lines. WhatsApp is a conversation, not a newsletter.
- One clear call to action. Reply, tap a link, or visit — pick one.
- Make replying easy. End with a question or an invitation to respond.
Step 6: Be ready when people reply
A broadcast is only the start. When someone answers, continue the conversation while their question is still current.
A few ways to keep response times low:
- Set an Away Message so people know when to expect a reply. See the auto-reply setup guide for steps.
- Save Quick Replies for FAQs (hours, price, location) so you answer in one tap.
- Send appointment reminders to cut no-shows for booking-based businesses.
- If selected conversations need monitoring after hours, an agent can answer within the job you approved and notify you when it needs a person.
Step 7: Measure the conversation, not the send
Track the basics so you know what's working:
- Response time — how fast you reply to inbound messages
- Reply rate — how many recipients respond to your broadcasts
- Conversion — how many WhatsApp conversations turn into sales or bookings
If a broadcast gets lots of opt-outs or no replies, your message or frequency is off. Adjust and test.
Keep permission visible
WhatsApp actively bans numbers that spam. Protect yours:
- ✅ Do message people who opted in or contacted you first
- ✅ Do make it easy to opt out ("Reply STOP to unsubscribe")
- ✅ Do keep frequency reasonable
- ❌ Don't add strangers or buy contact lists
- ❌ Don't send unsolicited promotions
- ❌ Don't use auto-dialers to message random numbers
Start with the free tools: a complete profile, a useful catalog, an away message and broadcasts only to people who opted in. Add automation when the follow-up work becomes too much to maintain by hand.
