FAQ

Frequently asked questions

Still deciding? Talk to our team and we will suggest the right route.

What is bulk messaging, and how does it help my business?

Bulk messaging means sending a large number of messages to targeted mobile numbers with a single click. Businesses use it to send important information to customers, for transactions, promotions and mobile marketing.

What is the difference between transactional and promotional SMS?

Transactional messages go to users who have opted in, and are usually generated by a system or API, such as OTPs and alerts. Promotional messages are bulk messages that are not limited to opted-in users.

Why is bulk messaging good value for business?

Bulk messaging costs less than any other medium of transactional or promotional communication. Businesses use it to:

  • Send personalised and customised information
  • Build brand awareness with existing and new users
  • Deliver information faster than any other channel
  • Communicate inside the organisation
  • Automate customer journeys
  • Send critical alerts, as banks and stock markets do
Why are some providers so much cheaper?

TRAI prescribes the SMS termination and transactional SMS charges for operators. Prices far below these levels usually mean poor routes, delayed delivery or fake delivery reports. Read the TRAI notice.
