Why messaging matters for banks, NBFCs & fintech
In banking and finance, a message is often the last line of defense — the OTP that authorizes a payment, the alert that flags a suspicious login, the reminder that prevents a missed EMI. Speed, security and compliance are not optional; they protect both the customer and the institution.
