What is promotional SMS?

Last reviewed 1 min readReviewed by BroadNet engineering
Quick answer

Promotional SMS is marketing sent by SMS — offers, campaigns, announcements, abandoned-cart nudges. Unlike transactional messages, it requires explicit marketing opt-in, must honour opt-out (STOP) and quiet hours, and is often registered and routed as a distinct traffic class. Done well on consented lists it converts strongly; sent without consent it wastes spend and damages sender reputation.

The long answer

Everything worth knowing, nothing that isn't.

§01

Consent is mandatory

Promotional SMS may only go to recipients who gave marketing consent, and every message must offer an easy opt-out. This is both a legal requirement in most markets and a deliverability protection. See /answers/how-to-handle-sms-opt-outs and /answers/what-is-dnc.

§02

Classify and register correctly

Promotional traffic is often registered under a separate sender ID and routed as its own class; mixing it under a transactional ID risks suspension. See /answers/how-to-register-sender-id and /answers/what-is-transactional-sms.

§03

Make it convert

Identify your brand, lead with one clear benefit and a single call to action, time it to local business hours, and segment the audience. See /answers/sms-marketing-best-practices and /answers/sms-marketing-roi.
