Preventing WhatsApp Blocks During Broadcasts
What Is This?
When you send a broadcast campaign to many customers at once, there's a risk of getting blocked â either by individual customers or by Meta's system. This guide focuses specifically on broadcast-related blocks and how to configure your Pixalink broadcasts to minimise risk.
Real-Life Example
Puan Anis manages marketing for Ayam Penyet Bestari chain (5 outlets). She sends weekly promotions to 5,000 customers via WhatsApp. By using Pixalink's Safe Mode with a 5-minute interval, sending only during business hours, and splitting her list into daily batches, she's never had a block in 6 months.
Broadcast Settings That Protect You
1. Choose the Right Broadcast Mode
Pixalink offers two broadcast modes:
| Mode | Best For | Protection Level |
|---|---|---|
| Standard Mode | Small lists (<500) | Minimal â sends at a fast fixed rate, no controls |
| Safe Mode | All lists, especially 500+ | Best â configurable intervals + weekend control |
Always use Safe Mode for lists larger than 500.
2. Set Proper Message Intervals
The interval between messages is your most important protection. Pixalink's Safe Mode offers four fixed interval presets:
| List Size | Recommended Interval |
|---|---|
| Under 500 | 1 minute |
| 500 â 1,000 | 2 minutes |
| 1,000 â 3,000 | 4 minutes |
| 3,000+ | 5 minutes, split across multiple days |
3. Split Large Lists Across Multiple Days
For large lists (3,000+), create multiple broadcasts targeting different customer segments:
- Instead of sending 5,000 messages in one day, split into 2-3 broadcasts across different days
- This looks more natural to Meta's system and reduces risk
- Schedule each batch during business hours (9 AM â 9 PM) for best results
4. Disable Weekend Sending
Toggle Include Weekends off unless your business specifically operates on weekends. This gives your number two rest days per week and reduces complaint risk.
Audience Targeting Tips
Filter Your Audience
Don't send to everyone â use Pixalink's broadcast filters:
- Active customers only â Exclude blocked or inactive customers
- Recent customers â Target customers active in the last 90 days
- Tag-based segments â Send relevant content to specific groups
- Exclude recent recipients â Don't message customers who already received a broadcast this week
Clean Your Contact List
Regularly review your customer list for:
- Invalid phone numbers
- Customers who've asked to opt out
- Duplicate entries
- Numbers that consistently fail delivery
What to Do If a Broadcast Gets Blocked
During the Broadcast
If you notice your broadcast is getting blocked mid-send:
- Pause the broadcast immediately from the Broadcasts page
- Check your quality rating in Meta Business Manager
- Wait 24-48 hours before resuming
- When resuming, increase the interval between messages
After a Block
- Review the broadcast content â Was it too promotional? Too long? Did it contain flagged keywords?
- Check the audience â Were you sending to old, unengaged contacts?
- Adjust settings â Increase interval, reduce daily volume, use Safe Mode
- Resume gradually â Start with a small test batch before sending to the full list
Broadcast Safety Checklist
- Using Safe Mode (not Standard) for 500+ recipients
- Message interval preset is appropriate for list size
- Sending during business hours (9 AM â 9 PM)
- Weekend sending disabled (unless needed)
- Audience filtered to active, opted-in customers
- Content is valuable and not spammy
- Quality rating is green before sending
- Large lists are split across multiple days
