Still have a question? Contact our team
What does a bulk SMS service provider do?
A bulk SMS service provider lets businesses send large volumes of SMS — offers, alerts, reminders and OTPs — to customers through an online panel or an SMS API, with delivery reports for every message.
What is the difference between promotional and transactional SMS?
Promotional SMS carry offers and marketing messages and go only to non-DND numbers during allowed hours. Transactional SMS carry account alerts, order updates and OTPs and can reach customers any time, as per TRAI guidelines.
Do you provide a bulk SMS API for websites and apps?
Yes. Our standard HTTP bulk SMS API works with any website, app, ERP or CRM, so you can send OTPs, alerts and notifications automatically.
Can I start my own bulk SMS reseller business?
Yes. Our white label bulk SMS reseller panel runs on your own domain with your logo, with zero setup cost and unlimited client accounts.
Do I need DLT registration to send bulk SMS in India?
Yes. TRAI rules require every business sending commercial SMS in India to register its entity, sender IDs (headers) and message templates on a DLT platform. Talk to our team for help with the process.
Which channels can I use besides SMS?
You can reach customers on WhatsApp, RCS, voice calls, IVR, missed call, AI voice agents, AI chatbots and AI video messaging — all from Bulk SMS India.
