OTP delivery at 500+ TPS for lending platforms and payment apps. EMI reminders that respect RBI Fair Practices windows. KYC status alerts wired into your CBS. Policy renewal messaging under IRDAI consent rules. WhatsApp for BFSI within Meta restrictions. Every send DLT-registered, DND-scrubbed, opt-out-honoured, and audit-ready for RBI inspection.
BFSI messaging is not like other industries. A 6-second OTP delay in a UPI transaction means an abandoned payment and a call to the helpdesk. A wrongly-scheduled EMI reminder at 8 PM crosses the RBI Fair Practices window and becomes a complaint to the ombudsman. A header suspension mid-day freezes every OTP for a bank's mobile app until someone at TRAI clears the ticket. Every failure mode has regulatory consequences beyond a lost sale.
The compliance stack is a moving target. TRAI DLT rules changed twice in 2024 alone. RBI's Digital Lending Guidelines put strict caps on collection contact frequency. IRDAI now requires explicit consent audit trails for every solicitation SMS. Meta reviews every BFSI WhatsApp template through a stricter category filter. Most teams have a compliance officer approving templates in a spreadsheet and hoping the ops team follows the rules on execution. It is not scalable.
Then there is peak-load OTP. When a payday hits and 40,000 UPI transactions happen in five minutes, single-vendor OTP infra breaks. Aggregator resellers throttle silently. Direct operator connections are the only route that holds. Most fintech teams find this out during the first quarter after series B, when the funnel data shows a mysterious 4 percent drop in payment success at 8 PM every Friday. It is not the payment gateway. It is the OTP.
BookMySMS is our own bulk SMS + WhatsApp gateway with direct enterprise API connections to the major DLT operators. We route BFSI OTP traffic every day at sub-3-second P95 and know the exact failure modes of every aggregator in the market. Managed messaging for your bank, NBFC, or insurer is the same infra applied with a dedicated ops team.

TRAI DLT is the entry gate. Principal Entity registration under Banking / Financial Services category, header approval with a recognised short code, template registration per message type (Service Implicit for OTP, Service Explicit for EMI reminders, Promotional for cross-sell). Every template versioned and tracked. When TRAI updates rules (as it did twice in 2024) we re-file affected templates ahead of the enforcement date.
RBI compliance is baked into the message scheduling layer. Transaction alerts fire immediately as required. Collection SMS respects the 8 AM to 7 PM window per Fair Practices Code. Contact frequency caps enforced per borrower per week per Digital Lending Guidelines. Every message identifies the lender by registered legal name. Suspicious pattern detection alerts your compliance officer weekly.
IRDAI rules for insurance: explicit consent capture and audit trail for solicitation communication, opt-out honoured within 24 hours, purpose tagging (servicing vs marketing) enforced per message. DPDP obligations (India's data protection law) cover consent, purpose limitation, breach notification wiring, and right-to-erasure across message history.
