Client Success Story
Case Study
An online retailer was losing customers at checkout because OTP messages arrived late. We moved their verification traffic to our dedicated high-speed OTP route and integrated the SMS API directly into their app. OTP delivery time dropped to a few seconds and failed sign-ups fell sharply. Because the same account also andled promotional and transactional SMS, the retailer could run festival offers and send order updates from one dashboard — with clear reports on what was delivered.
“Our OTPs now arrive instantly and our delivery reports are finally trustworthy. RichSol's SMS just works.”
