An SMS API is a tool that lets your app or system send and receive text messages automatically. It helps businesses deliver OTPs, alerts, and promotions quickly and reliably, without manual work.
SMS marketing sends promotional or transactional messages via text to customers with high open and response rates for offers, updates, reminders, and more.
DLT (Distributed Ledger Technology) registration is a mandatory process in India for businesses sending SMS to customers. It ensures message authenticity and prevents spam, as required by TRAI (Telecom Regulatory Authority of India).
To send SMS, businesses must register their brand, headers, and message templates on a DLT portal.
A2P SMS (Application-to-Person SMS) refers to text messages sent from a software or application to a user’s mobile phone.
Common examples include OTPs, alerts, reminders, and promotional messages. It’s widely used by businesses for automated, high-volume communication.
