Sending promotional messages on WhatsApp without getting banned requires following best practices and avoiding spammy behavior. Here's a complete guide to doing it safely and effectively, whether you're using WhatsApp Business or other tools:

✅ 1. Use WhatsApp Business API or Official Tools
Why: Meta allows promotional messages only through the WhatsApp Business API, not via personal or regular business accounts.

✔️ Options:
Meta WhatsApp Business Platform (via BSPs like Twilio, 360dialog, Wati)

WhatsApp Cloud API (directly from Meta)

These allow you to send approved message templates to opted-in users — legally and at scale.

🚨 2. Never Use Personal Accounts for Mass Messaging
Why: WhatsApp can detect automated or bulk sending from personal numbers and will flag or ban them.

🔴 Auto-forwarding tools, spamming groups, or using unofficial mods (like GB WhatsApp) is high-risk.

📜 **3. Always Get User Consent (Opt-In)
Why: Users must explicitly agree to receive messages from you.

Safe Opt-in Examples:
Via website checkbox during signup

Via "Send Me Updates" on Facebook/Instagram

QR code in your store or package

⚠️ Sending cold messages to unsaved or non-opted-in numbers = spam = risk of being reported = ban.

🧠 4. Use Message Templates (if on API)
Why: Promotional messages must be pre-approved.

Message types allowed:
Product launches

Offers or discounts

Event invitations

Reminders or order follow-ups

Use Meta's template builder or your BSP dashboard.

🎯 5. Segment Your Audience
Why: Personalized, relevant content reduces spam reports and increases engagement.

Examples:

Repeat buyers get loyalty offers

New leads get welcome promos

Inactive users get reactivation nudges

📊 6. Monitor Engagement & Spam Reports
Why: High block or report rates = warning or ban.

Check via:

WhatsApp Manager (Meta)

BSP analytics dashboard

🟡 Aim for high open rates and low block/report rates (below 0.1%)

🔄 7. Rotate and Warm Up Numbers (Advanced)
If sending large-scale promos:

Use verified business numbers via API

Slowly increase send volume to "warm up"

Never blast 1,000s of messages at once on a fresh number
