WhatsApp Messaging Guidelines for Businesses

WhatsApp allows bulk messaging for businesses, but only when it follows official WhatsApp messaging guidelines. Ignoring these rules is the main reason numbers get blocked or campaigns fail.

Key WhatsApp Messaging Rules

• User opt-in is mandatory: Businesses can message only users who have clearly agreed to receive WhatsApp messages. Scraped or purchased numbers are not allowed.

• Approved message templates are required: All bulk messages must use WhatsApp-approved templates for marketing, utility, or authentication messages.

• Promotional content must be clear and honest: Misleading offers, false claims, or spam-like language are not permitted.

• Easy opt-out must be available: Users should be able to stop messages easily, such as by replying “STOP.”

• Message frequency should be controlled: Sending too many messages can lead to complaints and lower message quality ratings.

• Correct message category must be used: Messages must be sent under the right category (marketing, utility, or authentication) as defined by WhatsApp.

• Business identity must be transparent: Messages should clearly identify the business and purpose of communication.

Following these WhatsApp messaging guidelines helps businesses maintain high delivery rates, protect their WhatsApp number, and build long-term customer trust. Siratel’s bulk WhatsApp marketing software is built on the official WhatsApp Business API, ensuring campaigns remain compliant and scalable.

Country-Wise WhatsApp Marketing Considerations

WhatsApp rules are global, but user behavior varies.

• India: High engagement, value-focused messages

• UAE: Branding and credibility matter

• Germany: Privacy and consent are critical

• Australia: Professional, non-pushy tone works best

• Brazil & LATAM: Conversational campaigns perform well

A good bulk WhatsApp marketing software supports country-wise segmentation, routing, and scheduling.
