What are the best practices for Multi-Channel Fallback?

Use Fallback for important transactional messages, test each channel separately first, keep wording consistent, map variables carefully, and monitor Delivery Reports and Analytics after go-live.

Recommended practices #

1. Use for transactional, not bulk promo. OTPs, alerts, reminders—not large marketing blasts.
2. Test each channel alone before combining in one flow.
3. Keep message meaning consistent across SMS, WhatsApp, and RCS.
4. Map variables explicitly when placeholder names differ between channels.
5. Use clear flow names so your team knows which API or campaign uses which mapping.
6. Leave trigger codes empty for maximum OTP coverage unless you need specific failure-only failover.
7. Disable instead of delete when updating templates—you can re-enable quickly.
8. Check Delivery Reports for a few real sends after launch.
9. Review Analytics weekly to spot channels that rarely deliver on the first try.
10. Use Preview on the manage list when all templates are selected to verify mobile appearance.
