Transactional SMS messaging is widely understood as any kind of message that is generated as a result of a user action, in direct relation to that user action.
This includes purchase confirmations, order updates, account alerts, schedule changes, reminders – just about anything that contains personalised information and was triggered by the action of one of your customers (even if there is a significant delay).
Transactional SMS messages give your customers the information they expect as soon as it is available, direct into their hands. It lets them know you’ve received an order & when it will be delivered; when an item is back in stock or ready for collection; that they need to renew a policy or subscription; a balance is running low; and that there has been a last-minute schedule change.
The bottom line is that much of transactional SMS messaging is just good manners and by that nature isn’t heavily sales focussed. But what you will get in addition to lower support costs is much happier customers, and happy customers are loyal customers who are more likely to buy off you in the future.
