Utility and authentication templates are the workhorses of transactional messaging. They cost far less than marketing and are tied to something the customer did or requested.
Use these for order confirmations, shipping updates, appointment reminders, and payment alerts. WA.Expert has ready formats for interactive utility, order details, and order status. They must relate to a real transaction, not a promotion.
These deliver one-time passwords and verification codes. The format is fixed by Meta and includes a copy-code button, which keeps OTP delivery fast and reliable.
Utility and authentication are priced low because they are expected, useful messages. Keep their content strictly transactional to stay in the cheaper category and avoid review issues.
