How to Build a WhatsApp Marketing Strategy (Framework)
1) Objectives and KPIs
Without KPIs, WhatsApp becomes "just chat." Define indicators like:
- response rate
- average response time
- conversion rate on CTA
- opt-out rate
- Average Order Value (AOV) from WhatsApp traffic
- ticket reduction on other channels
2) Contact collection: clear and sustainable opt-in
The best methods:
- Form on the website with checkboxes and information.
- Click-to-WhatsApp from ads or landing pages (with pre-populated message).
- QR codes in stores, on packaging, on receipts.
- Lead magnet (e.g., guide, discount) delivered via WhatsApp.
Tip: Always be clear about what you'll be sending (type and frequency). This improves list quality and reduces opt-outs.
3) Segmentation: The difference between conversion and spam
Segment at least by:
- origin (ads, organic, shop)
- interest (product/service category)
- stage (new lead, customer, recurring customer)
- behavior (openings, clicks, purchases)
- value (high/medium/low)
4) Tone of voice and editorial rules
WhatsApp is informal, but not improvised. Establish:
- style (professional, friendly, concise)
- sending times (avoid night time slots)
- frequency (e.g. max 1–2 promos/week)
- signature (operator or team name)
- escalation management (when it escalates to a human)
Types of Effective Messages (with Examples)
Transactional messages (high utility)
- Order Confirmation: “Order #12345 confirmed. Tracking: …”
- Appointment: “Reminder: tomorrow at 3:00 PM. Do you want to reschedule?”
Promotional messages (only if permitted and targeted)
- “Just for you: -15% on accessories until Sunday. Want to see the bestsellers?”
Conversational Messages (Qualification)
- “To help you better: are you looking for a solution for personal or business use?”
Retention messages
- “How did you like the product? If you want, I can send you three-step usage tips.”

Compliance, Consent, and Quality: How to Protect Your Brand and Deliverability
WhatsApp is an "intimate" channel: if a message isn't expected, the user reacts more strongly (blocking, reporting, opting out). This is why compliance isn't just a legal issue: it's a performance issue.
Practical principles:
- Transparency: explain what you will send and why.
- Minimization: ask only for necessary data.
- User control: easy opt-out.
- Relevance: send consistent messages with expressed interest.
- Sustainable frequency: better less, but useful.

Frequently Asked Questions (FAQ)
What is WhatsApp marketing and who needs it?
WhatsApp marketing is the use of WhatsApp for commercial and service communications: lead generation, nurturing, support, notifications, and promotions.

What's the difference between WhatsApp Business and the WhatsApp Business API?

Is it legal to send promotions on WhatsApp?

How to effectively collect WhatsApp contacts?
The most robust methods include opt-in forms on the website, in-store QR codes, click-to-WhatsApp from advertising campaigns, and lead magnets delivered via chat. The goal isn't to "make numbers," but to build a qualified list: a small number of truly interested contacts improve conversions and reduce opt-outs.
Which messages work best to increase sales?
Short, contextual messages with a single CTA work: cart recovery, product availability, expiration reminders, personalized offers, and post-contact follow-up. Personalization (name, interest, funnel stage) and timing are crucial. Avoid long, generic copy that seems spammy.
When should you switch to the WhatsApp Business API?
