Bulk messaging is powerful. But do it wrong, WhatsApp bans your number. Here's how to send thousands of messages safely.
I've helped 500+ Pakistani businesses with bulk messaging. These are the rules that keep you safe.
Rule #1: Only Message People Who Know You
Don't buy random number lists. Don't scrape numbers from Facebook. Only message your actual customers - people who bought from you, gave you their number, or asked for updates.
This Gets You Banned
Sending to random numbers, using scraped lists, messaging people who never contacted you. WhatsApp detects this fast. Your number gets banned permanently.
Rule #2: Don't Send Too Fast
WhatsApp watches sending speed. Send 1000 messages in 5 minutes? Banned. Wavvy automatically controls speed - sends messages gradually, looks natural to WhatsApp.
Safe speed: 10-15 messages per minute for new numbers. 20-30 for established numbers. Wavvy handles this automatically.
Rule #3: Personalize Messages
Don't send same text to everyone. Use variables. "Hi {{name}}, your order {{order_id}} is ready" - each person gets personalized message.
Wavvy supports variables in campaigns. Upload CSV with names, order numbers, custom data. Each message gets personalized automatically.
Rule #4: Give Opt-Out Option
Always include "Reply STOP to unsubscribe" in marketing messages. Remove people who ask to stop. This is not just good practice - it's required.
Rule #5: Warm Up New Numbers
Got new WhatsApp number? Don't send 5000 messages day one. Start small:
- Day 1-3: Send 50-100 messages daily
- Day 4-7: Send 200-300 messages daily
- Week 2: Send 500-1000 messages daily
- Week 3+: Send 2000-5000 messages daily
Pro Tip
Use multiple WhatsApp numbers. 3 numbers sending 1000 each = 3000 messages. Safer than 1 number sending 3000. Wavvy lets you connect unlimited numbers.
Rule #6: Monitor Delivery & Blocks
Watch campaign stats in Wavvy dashboard. If delivery rate drops below 80%, slow down. If many people block you, your message is probably spam.
Rule #7: Timing Matters
Don't send at 3 AM. Don't send during Jummah prayer. Best times for Pakistan:
- 10 AM - 12 PM: Morning, people check phones
- 3 PM - 5 PM: Afternoon, good response
- 8 PM - 10 PM: Evening, highest engagement
Rule #8: Quality Over Quantity
Better to send 500 messages to interested customers than 5000 to random people. Target your audience. Send relevant offers. Get better results, stay safe.
