Why this matters more than ever
Since Meta moved to conversation-based pricing, the distinction between service and marketing conversations has become a major cost driver. Many businesses still treat all outbound contact the same and end up overpaying significantly. Understanding the boundary lets you save money without changing how often you reach customers.
Service conversations defined
A service conversation begins when a customer messages you first and you reply within the 24-hour window using free-form messaging. The conversation is categorised as service automatically and priced accordingly. Service rates are low or zero in many regions, especially for common markets where Meta is incentivising adoption.
Marketing conversations defined
A marketing conversation begins when you send a marketing-category template to a customer outside the service window. Your intent is promotional or re-engagement-oriented, and the rate reflects that. Marketing is the highest-priced category in every market.
Where it gets blurry
If a customer asks about a product and you reply within the window, the entire interaction is a service conversation, even if you end up sending them an offer. The window protects intent: as long as the customer initiated, your response is service-rated. The moment you start a fresh outbound campaign, marketing rates apply.
Strategic implications
Encourage inbound contact wherever possible. Click-to-WhatsApp ads, QR codes on receipts, WhatsApp links on your website and signage all push customers to message first, opening service windows that you can use freely.
When marketing is the right choice
Some campaigns simply require outbound. New product launches to a dormant audience, time-sensitive sales, and seasonal pushes all justify marketing-rate conversations. The trick is to send them only to segments likely to respond, so the cost per outcome stays sensible.
Mixing categories cleanly
Avoid stacking marketing content on top of service conversations. If a customer messaged you with a support question, do not slip a promotional offer into the same window. The 24-hour service window is for the customer's enquiry, not a sneaky marketing send.
Reporting
Pull a monthly breakdown of conversations by category. If marketing dominates your spend but service conversations make up a tiny share, your acquisition flow is leaving money on the table. Push more inbound and watch the numbers rebalance.
