Take this example from Ulta: Instead of writing out “24-piece,” the USA Phone Number List company wrote “24 PC.” Most people can figure out what the message means, but it takes time to translate. The capitalization doesn’t help — a PC is, to most, a computer.

Make the best of your limited space by starting with something exciting. Flag a sale as “4 hours only!” or let SMS subscribers know when a deal is on its way out by telling them it’s their “LAST CALL” to shop. You can also just start with the goods. “BOGO” and “50% off” are things customers love to hear. Crafting the perfect SMS marketing message takes more time than you have characters, but doing it right pays off.
