Bulk SMS is the same mechanism everywhere — a message, a list, a network delivery report — but what organisations send with it differs completely by sector. These guides describe the messages each industry in Zambia actually sends, how they send them (spreadsheet upload, scheduled reminders, API integration) and the sample messages that work.

Transactional or marketing?
Most sectors send both. A school's fee reminder is transactional; its open-day invitation is marketing. A retailer's order update is transactional; its Friday promotion is marketing. The distinction matters for consent: transactional messages are expected by the recipient, marketing messages need an opt-in and an opt-out. The transactional SMS and SMS marketing guides cover each.
