Bulk SMS Service in Sri Lanka

What is bulk SMS?

Bulk SMS is one-to-many messaging: promotions, announcements and updates to a contact list. Use the portal for CSV campaigns or the API (SEND_BULK_SAME / SEND_BULK_DIFFERENT) for software-driven sends.

Bulk SMS Sri Lanka campaign workflow

Upload contacts (CSV), choose Sender ID, write the message in Sinhala, Tamil or English, personalize with merge tags, schedule or send immediately, then watch delivery in the dashboard.

Credits never expire, so seasonal campaigns do not force you to burn a monthly bucket.

When to use bulk vs transactional SMS

Use bulk SMS Sri Lanka for promotions and announcements. Use transactional SMS for orders, OTPs and account alerts that must fire from your system in real time.

Both share gateway routes and reporting on one account.

Compliance and opt-out

Keep lists clean and honour opt-outs. Marketing traffic should only go to people who expect it. Transactional alerts follow a different consent pattern than promo blasts.
