The short answer: text messaging (SMS and messaging apps) works best for short, timely, useful messages: appointment reminders, order and service updates, onboarding nudges, quick support conversations and renewal reminders. Customers read texts far more often than email, so use messaging sparingly, get clear permission, keep it two-way and connect it to your CRM so every message has context.
Why messaging matters for CX
- It's where customers already are. Most people check their phones constantly and prefer quick messages to phone calls.
- It's fast. Texts are usually read within minutes, which makes them ideal for time-sensitive updates.
- It's two-way. Customers can reply, confirm or ask a question without switching channels.
- It's asynchronous. Customers can respond when it suits them, without waiting on hold.
The best use cases
| Stage | Example messages |
|---|---|
| Onboarding | Welcome message, setup reminders, "your account is ready" |
| Service updates | Appointment reminders, delivery tracking, outage alerts |
| Support | Ticket updates, quick questions answered by text, follow-up after resolution |
| Feedback | One-question CSAT or NPS surveys after key interactions |
| Retention | Renewal reminders, payment issues, check-ins with at-risk customers |
Tips for using messaging well
- Get clear consent. Only text customers who have opted in, and make opting out easy.
- Be useful, not noisy. Every message should help the customer. Limit marketing texts.
- Keep it short and personal. Use their name, say who you are and get to the point.
- Time it well. Respect time zones and business hours.
- Make replies count. Have someone, or a well-designed AI assistant, ready to respond.
- Connect it to your CRM. Log messages against customer records so the whole team has context.
- Follow the rules. Messaging is regulated in most markets (for example TCPA in the US and GDPR and PECR in the UK and EU), so check requirements before you start.
Frequently asked questions
Is SMS or email better for customer communication?
Both have a place. Use SMS for short, urgent or time-sensitive messages, and email for longer, detailed or less urgent information.
Can AI handle text conversations with customers?
