# 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.
