WhatsApp sending limits depend on the messaging product and the account's current configuration. A Business App broadcast-list limit is not a universal Business Platform limit. Verify your account's rules before sizing an outbound campaign.
Separate three different constraints
The App's broadcast mechanism, Meta's Business Platform controls and your software subscription allowance are separate. A larger software allowance does not override number quality or an account restriction. Conversely, an API capability does not mean a provider has included unlimited campaign capacity in your plan.
Review the current official documentation and the sending controls shown in your account. Avoid copying an old universal limit from an article into an operational plan.
Check the audience before the batch size
Permission and relevance matter even for a small campaign. Remove opted-out contacts, validate phone numbers and avoid duplicates. Segment customers by a real reason for receiving the offer rather than sending to the largest available list.
A distributor might notify retailers who asked about a particular category. A broad unrelated offer to every historical contact can create complaints and a worse customer experience.
Templates and quality
Check template approval, language, required variables and message category. A template edit or account change can affect a campaign that worked previously. Keep a process for staff to investigate a rejection or failure instead of automatically repeating the send.
A safe operational rehearsal
- Review a small eligible segment and its source.
- Send a permitted test message and inspect the result.
- Verify the account's current available capacity.
- Run the intended small batch.
- Review failures, replies and opt-outs.
- Reconcile uncertain delivery before resending.
Read the right outcome
A job reaching its final status means the job finished processing. It does not necessarily mean every recipient received or read the message. Review individual message statuses where available and keep failed recipients distinct from successful ones.
Repeating the entire audience because a few messages failed can duplicate a promotion for people who already received it. The team should understand retry behavior before using bulk sending at scale.
Continue the conversation
Plan staffing for the replies. HeidelAI combines broadcasts with customer conversations, AI assistance and a shared inbox, but the business still needs ownership for negotiation and exceptions. A useful limit is also an operational one: send at a scale your team can follow through on.
Put the guide into practice
Prepare content with the marketing template examples, estimate the message and platform cost, and review the broadcast workflow before launch.
