Zero Failed Message: WhatsApp + SMS Fallback for Guaranteed Delivery
Have you ever sent an important message to your customers, only to realize that they haven't received it? For businesses, every message matters– be it order updates, OTPs, reminders or confirmations.
Missed WhatsApp delivery= Missed Opportunity
This is why having a backup system isn’t optional anymore, it’s a necessity for every business.
Meet SMS Fallback: the backup system that your business needs. When the initial messaging method fails, maybe due to lack of internet connectivity, unsupported technology or server issues, it ensures that message is delivered. Critical information such as OTPs, transaction alerts, payment reminders and other important information is delivered seamlessly to the users, even if they are offline or don’t have a compatible application installed.
Why is SMS Fallback relevant?
Message fallback acts as a safety net that guarantees message delivery when primary channels for message delivery, including RCS(Rich Communication Service), WhatsApp or app push notifications, fails.
SMS Fallback is relevant for:
Guaranteed Delivery of Messages
Universal Reach
Critical Communications
Device and Network Compatibility
No dependency on external apps.
When can businesses use SMS Fallback?
SMS fallback becomes crucial for sharing any transactional messages such as OTPs, order updates, payment alerts, delivery notifications, appointment reminders, ticket details, etc. Anything wherein, even a 10-second delay can cause drop-offs, failed logins, or customer frustration, such messages simply can’t afford to get stuck on WhatsApp.
WhatsApp fallback is particularly important in geographies that have low network reliability, areas with inconsistent WhatsApp usage patterns, or where customers switch devices frequently.
Step-By-Step Delivery Flow of SMS Fallback
The Fallback works intelligently to redirect failed WhatsApp Messages to SMS, hence ensuring guaranteed reach without manual intervention. To implement sms fallback for WhatsApp campaigns smoothly, businesses follow a simple yet smarter flow.Here’s a detailed guide to how the message flowback works:
Detect Delivery Failure
As soon as the message is sent via WhatsApp, the system automatically listens to delivery events(whether sent, delivered, failed, undelivered). If WhatsApp detects it as ”failed”, fallback is triggered.
Switch to SMS Gateway
As soon as the message is detected as “failure” , the message is then routed through the SMS gateway, where a pre-configured SMS fallback template is triggered. Such templates are created beforehand specifically for this scenario. The default template is already optimized for SMS, with no buttons, media, or interactive elements, ensuring smooth and reliable delivery.
Businesses must configure rules that balance cost efficiency and delivery reliability.
WhatsApp Fallback Compliance Checklist
Here’s a quick compliance checklist that makes this switch effortless.
1. Handling Opt-Ins the Right Way
If a user has only opted in for WhatsApp, SMS fallback should not be triggered without additional consent. Also, it is essential to respect user’s unsubscribed keywords, country- specific opt-out rules and DND lists in order to maintain trust.
2. Keep SMS Short, Clear, yet Actionable
Since SMS has character limits, avoid long sentences or unnecessary details. Make the key information—OTP, order ID, delivery update, or link—appear early in the message. Remove jargon and keep the tone consistent with your brand to maintain a smooth experience, even without rich UI elements.
3. Follow Local Regulations Carefully
Every country has its own rules for SMS: approved sender IDs, quiet hours, promotional restrictions, consent requirements, and template approvals. Configure your fallback settings to automatically respect regional policies so messages aren’t blocked or flagged. Ensuring compliance also improves delivery rates and user trust.
Never let any ‘failed’ message disrupt your customer journey. With Anantya.ai, you can implement a reliable fallback strategy with WhatsApp API that automatically reroutes undelivered messages to SMS, ensuring every notification—whether transactional or promotional—reaches your audience.
