Transactional SMS is a type of text message communication that companies mostly utilise to give their clients relevant information at the right moment. Transactional SMS messaging is prompted by certain actions or events connected to individual consumers' contacts with a business, as opposed to promotional or marketing SMS, which are frequently sent to broad groups of users to sell products or services. Important details about a transaction or continuing business connection are usually included in these messages; examples include order confirmations, shipping updates, account alerts, appointment reminders, and verification codes for account authentication. They function to inform, engage, and notify clients on significant events or developments pertaining to their accounts or business dealings.
