How to choose between WhatsApp, SMS, and RCS for customer campaigns
A practical guide to choosing the best messaging channel for promotions, alerts, support, and high-intent customer actions.
Choosing the right messaging channel depends on the business goal, customer intent, speed requirements, and content format.
SMS is strong for fast reach and alerts. WhatsApp works well for conversational journeys and rich engagement. RCS is useful when you want richer native mobile experiences with branded content.
When SMS works best
Use SMS for OTP, alerts, reminders, urgent updates, and audiences that need universal device reach.
When WhatsApp works best
Use WhatsApp for support, catalogs, CTA-based flows, lead nurturing, and two-way conversations.
When RCS works best
Use RCS when your campaign depends on visuals, suggested actions, and a more app-like messaging experience.
