2026 SMS Compliance: How to Legally Send Bulk Marketing Messages

In 2026, mobile carriers and regulators (TCPA, GDPR, A2P 10DLC) have implemented stricter filters. To ensure your business communication reaches its destination, you must prioritize legal compliance. This guide explains how to use SMS Deliverer as a secure, local gateway for your professional campaigns.

1. Permission-Based Marketing (Opt-In)

Consent is the foundation of legal SMS marketing. You must obtain explicit permission before sending promotional content. Using purchased lists is not only ineffective but also illegal under most jurisdictions.

Pro Tip: Use your website or offline store to collect phone numbers with a clear disclosure that the user will receive marketing alerts.

2. Automated Opt-Out Handling

Every marketing message must provide an easy way to unsubscribe. The "STOP" keyword is the industry standard. Failure to respect opt-out requests can lead to heavy fines and SIM blocking.

Our desktop SMS software includes a powerful Keyword Trigger feature that automatically blacklists contacts who reply with STOP.
