What is MM Lite?

Marketing Messages Lite, or MM Lite, is Meta’s optimized delivery system for eligible WhatsApp marketing messages in HighLevel. It helps businesses send promotional WhatsApp messages more efficiently by prioritizing delivery to contacts who are more likely to engage. MM Lite is designed for marketing use cases, while standard WhatsApp messaging continues to support conversations, support, and other non-marketing communication types.

MM Lite helps businesses improve WhatsApp marketing performance without rebuilding existing templates, workflows, or campaigns. Once enabled, eligible marketing messages can use optimized delivery logic while your existing WhatsApp setup continues to work as expected.

When To Use MM Lite

MM Lite is best suited for promotional WhatsApp messaging where timing, engagement, and audience quality matter. Understanding when MM Lite applies helps you choose the right sending approach for each type of customer communication.

Use MM Lite for eligible WhatsApp marketing messages, such as:

• Promotions

• Free-form replies within an active customer service window

WhatsApp messages are categorized into Marketing, Utility, Authentication, and Service message types, and each category can follow different pricing and sending behavior. For pricing and category details, review the WhatsApp Pricing, Billing, and Rebilling Guide.
