## Steps

1\. Create a VeloBotix account and register a Sender ID. 2. Export consenting contacts to CSV. 3. Remove landlines and duplicates. 4. Write a short message; check Unicode if you use Sinhala or Tamil. 5. Send a test to your own SIM. 6. Schedule or send. 7. Review delivery reports before the next blast.

## Portal vs API

Use the portal for marketing teams. Use SEND\_BULK\_SAME or SEND\_BULK\_DIFFERENT when your CRM should fire the campaign.

No. Buy when you need volume; unused credits stay on the account.
