The route your message uses is dependent on the type set for the message, either promotional or transactional. When purchasing a new number using the Amazon Pinpoint console you will be prompted to choose the route type.
Promotional routes are typically marketing or sales-related messages. Some countries or regions have quiet time hours when you're not permitted to send promotional messages. A transactional route is for more time-sensitive messages, such as password resets or one-time passwords. This can be applied to the number when you're purchasing a new number or can be passed as an optional parameter in the SendMessages operation of the Amazon Pinpoint API. When sending a message using that number as the originator, Amazon Pinpoint chooses the applicable promotional or transactional route.
You pass the route type as an optional parameter using the SendMessages operation of the Amazon Pinpoint API. In some cases you might use a SenderID as the originator, or you might have a shared pool of numbers. If you have both transactional and promotional numbers associated with your account for the destination country, Amazon Pinpoint chooses a transactional number by default. Delivery receipts and the Delivery dashboard show the route as either promotional or transactional, based on the chosen number.
