What is a bulk SMS service?
A bulk SMS service lets a business send the same or personalised text message to thousands of mobile numbers at once, from an online panel or through an SMS API. In India it is the most reliable way to reach every customer, because SMS works on every phone and every network without internet or an app.
Bulk SMS India offers three routes: promotional SMS for offers and campaigns, transactional and service SMS for alerts and updates, and OTP SMS for logins and payments. Every message is sent with your DLT-registered sender ID and template, and you see a live delivery report for each number.
