3. Personal number vs API number mass distribution: How to choose for overseas business

1. What is the difference between personal number vs API number mass distribution?

Mass distribution is the core requirement of private domain operations, but the mass distribution capabilities of different versions vary greatly, especially pay attention to the title risk of personal accounts.：

• Mass issuance of personal accounts: high risk, limited quantity, only suitable for “small-scale access”

1. Operable range: Only the old account (used for more than 1 month, and there is an active chat every day) is suitable for a small number of mass releases. It is recommended to send ≤20 mass releases per day, and it needs to be sent at intervals; mass releases of new accounts can easily trigger risk control. 
2. Core risks: Mass distribution in large quantities (more than 50 pieces per day), sending the same copywriting/link, and adding friends frequently will be judged as “spam marketing” by Meta, and the account blocking rate exceeds 90%, and it is difficult to recover after the ban. 
3. Applicable scenarios: The “personalized reach” of small businesses to old customers (such as exclusive discounts and after-sales reminders for old customers) is not suitable for large-scale renewal or promotion.
4. Sending restrictions: send it through the broadcast list or manually, up to 256 contacts at a time; it can only be sent to contacts who have saved your number; automated operations are not supported (mass distribution or tracking cannot be done by the system).

Applicable scenarios: Small-scale maintenance of old customers and private domain interaction.

• Mass issuance of API numbers: low risk control, controllable quantity, suitable for "enterprise-level large-scale operation”

1. Operational scope: There is no clear limit on the number of items, it supports batch delivery of personalized content, and it can be combined with tags to accurately filter people. 
2. Core advantages: Meta has clear rules for the “marketing compliance” of API numbers (if customers need to agree to receive messages first), and the title rate under compliance operations is less than 1%; at the same time, it supports automated triggering, and the efficiency is 10 times higher than that of personal numbers. 
3. Applicable scenarios: “Large-scale customer activation” and “full-link automated reminder" for cross-border enterprises).
4. Usage restrictions: Active messages (the first message sent by the enterprise) are billed by article, and charged by region and type; they can only be accessed through the official BSP, which is more expensive.

Applicable scenarios: Bulk marketing, after-sales notification, event promotion, AI customer service.

Reduce the risk of personal account title and ensure that the content sent complies with Meta regulations.

2. Why is it easy for personal accounts to be blocked in bulk?

WhatsApp's risk control mechanism is very strict, especially for personal accounts with abnormal transmission frequencies.

Common title trigger behaviors include：

• Send too many contacts in bulk at once；
• Send duplicate content, links, or advertising information；
• Users who have not saved your number frequently complain about "spam messages”；
• Use non-conforming third-party plug-ins and mass distribution tools for simulators.

Suggestions to avoid titles：

1. Control the transmission frequency (it is recommended not to exceed 50-100 messages per day)；
2. Send diversified content (with emoticons, pictures are more natural)；
3. Keep the rhythm of the real chat, don't send out template ads in bulk with one click；
4. Avoid frequent switching of IP and device logins.
