What Are Washington SMS Guidelines?

Washington SMS guidelines are state-level rules that define how businesses can send text messages to people in Washington.

They outline what is considered acceptable content, when messages can be sent, and what type of consent is required before texting someone.

They function as a compliance framework within SMS communication so that marketing, reminders, and alerts respect consumer privacy and state consumer protection laws.

These guidelines depend on accurate records of consent, opt-in and opt-out data, message timestamps, and the nature of the content being sent.

They shape the final message by influencing wording, timing, and frequency so texts are transparent, clearly identified as promotional or informational, and easy to stop.

By following Washington SMS guidelines, businesses make sure recipients experience messages as relevant, lawful, and respectful rather than intrusive.
