What are the limits on the number of audience members in a campaign?
📊 Limits on the Number of Audience Members in a WhatsApp Campaign
When running a WhatsApp campaign via MyOperator, your audience size is restricted by two layers of limits:
- Platform-level limits (MyOperator)
- Meta-imposed daily messaging tiers (WhatsApp Business Platform)
🔢 Audience Limits
Constraint Source | Limit | Notes |
|---|---|---|
MyOperator Platform | Up to 5,000 contacts per campaign run | Audience file uploads beyond 5,000 must be split into separate campaigns. |
Meta (WhatsApp) | Tier-based daily cap (1K, 10K, 100K, or Unlimited) | Applies per phone number linked to your WABA. If your tier is lower than 5,000, the lower value applies. |
🧪 How This Works in Practice
Scenario | Outcome |
|---|---|
Upload 3,000 contacts | Runs successfully (within both limits). |
Upload 6,000 contacts | Must split into two campaigns of ≤ 5,000 each. |
Meta tier = 1,000/day, but you upload 5,000 | Only the first 1,000 messages are delivered; the rest fail. |
⚠️ Important Considerations
- Meta assigns messaging tiers based on account health, message quality, and usage history.
- Typical progression: 1K → 10K → 100K → Unlimited per day.
- To scale faster, maintain a high-quality score and gradually increase send volumes.
- Platform-level (5,000 contacts) is a technical safeguard, while Meta tiers are policy-driven limits.
✅ Best Practices
- Check your current Meta messaging tier before planning large campaigns.
- Always split lists larger than 5,000 into clearly named batches (e.g., "July Promo – Batch 1").
- Maintain high-quality engagement (low block/report rate) to move up tiers.
- Keep a buffer in campaign planning—don’t schedule 5,000 sends if your Meta tier is capped at 1,000.
✅ Summary
- Per campaign (MyOperator): Max 5,000 contacts.
- Per day (Meta): Tier-based (1K → 10K → 100K → Unlimited).
- The lower limit always applies between the two.
