Types of SMS Services You Should Know
Transactional SMS

Used for marketing campaigns, offers, and updates. These messages are sent only during TRAI-approved hours and help businesses reach a large audience effectively.
A professional SMS marketing company in Delhi will offer both services along with advanced segmentation tools, helping you target the right audience with the right message at the right time.
Common Mistakes to Avoid
- Choosing only based on price – Going for the cheapest bulk SMS provider in India can compromise delivery rates, support, and reliability. Always balance cost with quality.
