Njiwa is built for bulk. You can send one identical message to thousands of recipients in a single send — pick or paste your list, write once, and it goes out to every phone.
Can I use my own sender ID?+
Yes. Send from your own branded alphanumeric sender ID so customers instantly recognise you. If you don't have one yet, every organization can use the free shared global sender-ID pool to start sending immediately.
How do I know if my messages were delivered?+
Njiwa gives you real-time delivery reports (DLR). As mobile networks send back status callbacks, you see delivered and failed status per message — so you always know exactly what reached its destination.
