Case study: weekly retail SMS campaigns
How they send
Marketing exports a consented list, writes a short offer, and sends from the portal with a registered Sender ID. They keep OTP and receipts on the API so promo copy never lands on login messages.
Scale
The team described weekly sends on the order of 80,000 customers. Unicode (Sinhala/Tamil) is used only when the extra credits are worth it.
