⚡Quick answer -

• If your campaign audience is larger than your remaining daily quota, WhatsApp only delivers messages up to your limit. The rest of the messages will fail, and you’ll see an error:
  “Audience size exceeding remaining quota, some messages may not be delivered.”
• Only the first quota-compliant batch is delivered.

When should I use this guide?

Read this whenever you’re planning a WhatsApp broadcast that might reach more users than your current tier allows, so you can adjust the audience in advance and avoid quota errors.

1. What is the Remaining Quota?

• The remaining quota refers to the number of business-initiated conversations a WhatsApp Business API phone number can still initiate within the current 24-hour moving period, based on its messaging limit. This quota decreases each time a business-initiated conversation is started and resets after 24 hours from the time a conversation was initiated.
• To calculate the remaining quota, subtract the number of conversations already initiated in the last 24 hours from your current messaging limit.

For example:
If your messaging limit is 1K (1,000 conversations) and you have already initiated 300 conversations, your remaining quota is 1,000 - 300 = 700 conversations.

Factors Affecting Messaging Quota:
1. Current Messaging Limit: Determined by the tier your business is in (250, 1K, 10K, or higher).
2. Conversations Already Initiated: The number of business-initiated conversations started within the last 24 hours.

2. WhatsApp daily limit & error message

WhatsApp sets a 24-hour rolling messaging limit based on your current tier (e.g., 1K, 10K, 100K messages per day). This limit applies to business-initiated template broadcasts.

If your campaign tries to reach more users than your remaining quota, our system stops once the limit is hit and shows:

"Any users beyond the remaining limit won’t receive the message."

3. Example: Tier 1 (1,000-user limit)

Assume your current tier allows you to message up to 1,000 unique users in a rolling 24 hours.

So effectively, only the first 1,000 users (or whatever your remaining quota is) receive the message.

4. What to do next

1. Check your current tier limit
• Go to WhatsApp Business Manager → Account → Phone Numbers to see your messaging limit and quality rating for each number.
2. Resize your audience
• Bring your campaign size within your remaining limit (e.g., send 900 instead of 1,100 if your limit is 1,000 and you’ve already used 100).
3. Work towards a higher tier
   Meta upgrades your tier automatically when both conditions are met:
• You regularly use a large portion of your current limit (roughly half to twice your limit over 7 days).
• Your Quality Rating stays Medium or High (low complaint/block rates).
4. In simple terms:
• Send at meaningful volume (not tiny batches).
• Keep content relevant and non-spammy so users don’t block/report you.
• Collect opt-ins.
• Meta reviews this daily and bumps you to the next tier automatically once the criteria are met.

5. Best practices to avoid hitting the cap

• Plan in batches by tier
• If you’re on a 1K limit and need to message 3K users, split into multiple days or wait for a higher tier instead of forcing all in one go.
• Keep a safety buffer
• Don’t sit exactly on the limit. If your cap is 1,000, send 900–950 per day in a campaign, so minor recalculations don’t trigger an error.
• Watch your quality rating
• Avoid spammy or irrelevant templates. Too many blocks/reports can prevent tier upgrades or even reduce your limit.
• Warm up before big blasts
• Before a large campaign, you can test it by sending it to yourself first.
