SMS stands for Short Message Service: the traditional text message sent from a cell phone. SMS marketing uses this channel for brief commercial communications, such as a discount code, a shipping notification, or a reminder. It doesn't require an internet connection or a downloaded app—just a cell phone number.

Why does it matter?

Its biggest advantage is its reach: it can reach almost any phone, even without mobile data. It's straightforward and quick to read, making it useful for urgent messages or those with a deadline.

Its limitations are also clear. It supports only a small amount of text, doesn't allow rich images or fluid conversations like WhatsApp, and each message costs money. That's why it works best as part of an omnichannel strategy:

• Short, to-the-point messages: an offer, a deadline, a link.
• Key moments: the last day of a promotion or an important announcement.
• Supplement: for customers who do not respond through other channels.
• With permission: only to those who agreed to receive text messages, with a simple way to opt out.

Story mode

Lucia shops at an online sports store, but she almost never opens the emails, and she hasn't enabled WhatsApp for that brand. On the last day of a sale, the store sends her a short text message: "Lucia, the 20% off running gear sale ends today. Use the code RUN20." She reads it on her way to work, goes to the website, and buys a pair of performance socks before midnight.
