Two jobs, two kinds of traffic

Promotional SMS sells or announces: offers, events, campaigns. Transactional SMS supports an action the user already started: OTP, payment confirmation, order update, balance notice.

Mixing them carelessly hurts delivery reputation and confuses customers. Yoola SMS supports both patterns from one platform — you still need to choose the right content and timing.

Promotional SMS

Transactional SMS

Practical rule for Ugandan SMEs

If the user would be surprised to get the message, treat it as promotional. If the user would be blocked in their task without the message, treat it as transactional.

On Yoola SMS

New accounts can start with campaign sending from the dashboard. API users sending OTPs and alerts should follow the transactional/API guidance in the docs and keep templates clean. Same credit wallet; different operational discipline.
