Case Studies
How businesses use PromoMarketingSolution to solve real communication problems — from OTP delivery to delivery-day support.
Note: the scenarios below are illustrative examples of how our channels are typically used, not published client case studies. Real, named case studies will replace these as customers agree to be featured.
E-commerce & Retail
Cutting delivery-day support calls with proactive WhatsApp updates
- Problem
- Customers were calling support to ask where their order was, overloading the call center during peak sale periods.
- Solution
- Automated WhatsApp Business API notifications at each shipment milestone, with a two-way chat option for exceptions.
- Result
- Fewer inbound status-check calls, freeing the support team to handle exceptions instead of routine queries.
BFSI & Fintech
Moving OTP delivery to a multi-channel fallback
- Problem
- SMS-only OTP delivery meant failed logins whenever a carrier route degraded, especially during high-traffic periods.
- Solution
- SMS OTP with automatic Voice OTP fallback when SMS delivery is delayed, using redundant carrier routing.
- Result
- Fewer failed verification attempts and fewer support tickets related to "OTP not received."
Logistics & Delivery
Replacing manual dispatch calls with automated IVR alerts
- Problem
- Dispatch teams were manually calling drivers and customers to confirm pickup and delivery windows.
- Solution
- Outbound Bulk Dialer (OBD) campaigns confirming pickup/delivery windows, with IVR options to reschedule.
- Result
- Reduced manual outbound calling load on the dispatch team.
