SMS Marketing and Text Message Automation

SMS marketing lets you send promotional messages, alerts, and automated text sequences directly to your customers' phones. With open rates above 90% and most texts read within three minutes, SMS is the highest-engagement marketing channel available. This guide covers everything from setting up your first campaign to managing compliance, carrier routing, and deliverability across multiple providers.

Why SMS Marketing Works

Email open rates average 20-25%. SMS open rates consistently exceed 90%. The difference is simple: people check their text messages. Unlike email, which gets filtered, tabbed, and buried, a text message arrives directly on the lock screen and gets read almost immediately.

For businesses that need timely communication, SMS is unmatched. Appointment reminders, flash sales, shipping notifications, two-factor codes, and urgent alerts all perform dramatically better over text than email. Customers who opt into your SMS list are actively telling you they want to hear from you on their most personal device.

The catch is that SMS marketing comes with strict legal requirements. Federal law (TCPA), carrier registration (10DLC), and opt-in rules all apply. Getting these wrong can result in fines of $500-$1,500 per message. The compliance guides below cover every requirement in detail so you can run campaigns confidently.

How SMS Marketing Works on This Platform

The SMS Broadcast app handles bulk text messaging with features built specifically for deliverability and compliance. Here is what makes it different from basic SMS tools:

12 SMS providers with automatic carrier-based routing. Messages to AT&T numbers go through providers with the best AT&T delivery rates, Verizon numbers route through Verizon-optimized providers, and so on. This is technical infrastructure that most SMS platforms do not expose.
Carrier lookup on every contact. The system identifies each phone number's carrier before sending, enabling intelligent routing decisions instead of blindly sending through one provider.
Volume management across providers. Large campaigns are distributed across multiple sending numbers and providers to avoid triggering carrier rate limits or spam filters.
Click tracking with bot detection. Links in your messages are tracked for clicks, and the system filters out automated bot clicks from carrier security scanners so your analytics show real human engagement.
Automated sequences. Set up drip campaigns that send timed follow-up messages over days or weeks. Combine with email campaigns for multi-channel sequences.
AI-powered replies. Connect an AI chatbot to handle incoming text replies automatically, turning one-way broadcasts into two-way conversations.

Compliance and Legal Requirements

SMS marketing is heavily regulated in the United States. Before sending your first campaign, you need to understand three layers of rules:

Federal Law (TCPA)

The Telephone Consumer Protection Act requires express written consent before sending marketing texts. This means you need a clear opt-in process where the subscriber specifically agrees to receive text messages from your business. Verbal consent is not enough for marketing messages. The TCPA compliance guide covers exactly what constitutes valid consent.

Carrier Registration (10DLC)

All business text messaging in the US now requires 10DLC registration. This is a carrier industry program that verifies your business identity and the type of messages you plan to send. Without registration, your messages will either be blocked or severely throttled. The 10DLC registration guide walks through the process step by step.

Opt-Out Handling

Every SMS you send must include a way to opt out, and you must honor STOP requests immediately. The platform handles STOP, UNSUBSCRIBE, and CANCEL keywords automatically, adding the number to your suppression list. See automatic opt-out handling for details.

Deliverability and Carrier Routing

Sending a text message is easy. Getting it delivered consistently at scale is the real challenge. Carriers actively filter business messages, and each carrier has different rules about what gets through and what gets blocked.

The platform's carrier-based routing system addresses this by maintaining delivery relationships with 12 different SMS providers. When you send a campaign, each message is routed through the provider that has the best delivery track record for that specific carrier. AT&T messages go one route, T-Mobile another, Verizon another. This is the same approach large enterprise messaging companies use, but available at any scale.

The carrier-based routing guide explains how this works in detail, and the SMS deliverability guide covers common delivery failures and how to fix them.
