Emails often end up in the spam folder, and push notifications require an app to be installed. Nevertheless, many small and medium-sized businesses are looking for a channel that reliably reaches their audience at the right moment. This is exactly where text messages come in.
Almost everyone opens a text message within a few minutes. What may sound like an almost forgotten channel is actually one of the most direct ways to reach your customers.
This post shows you the Strengths and Limitations of SMS, the legal framework in the DACH region, as well as twelve ready-to-use text modules.
Why Text Messaging Is Once Again Relevant for Customer Retention
A text message reaches virtually every mobile device—without requiring an installed app, a data connection, or a spam filter. This technical robustness makes it unbeatable for certain types of messages. The second reason is attention: A text message is usually read within a few minutes.
The Role of SMS in Today's Communication Mix
Email remains the go-to channel for in-depth information and storytelling. Push notifications are best suited for engagement-focused messages aimed at active app users. SMS is reserved for the few, truly important messages that need to be seen right away. Read the article for more on the big picture Push Notifications for Customer Loyalty.
When SMS Marketing Is Really Worth It
Three criteria can help you make this decision: The message is time-sensitive, it is personally relevant, and there is a clear next step. If any one of these three criteria does not apply, email or a push notification is almost always the better choice.
The Most Important Use Cases
- Appointment and Reservation Reminder: usually 24 hours in advance, fully automatically by the system.
- Reward Unlocked: A message that highlights a specific benefit and the next step.
- Voucher Expiration Reminder: A single reminder sent a few days before the expiration date noticeably increases the number of redemptions.
- Limited-time offer: A reference to a time-sensitive promotion targeting a predefined segment.
- Order or Pickup Notification: A classic for Click & Collect, often combinable with a loyalty offer.
- Reactivation: as the final step in a multi-step Winback Campaign, not first.

Legal Guidelines in Germany, Austria, and Switzerland: A Concise Overview
- Opt-in required: Express consent is required; pre-checked boxes are not sufficient.
- Clear Purpose: When registering, it must be clear what the number is used for.
- Unsubscribe link in every message: The default is „Log out: STOP“ or a short link.
- Sender clearly identifiable: The brand must be clearly identifiable.
- Transactional SMS messages are different: Confirmation emails are not considered advertising, but they must still comply with data protection regulations.
Text Message, Push Notification, or Email: The Decision Chart
| Criterion | Text Message | Push | |
|---|---|---|---|
| Unit Costs | high (5–10 cents) | very low | very low |
| Text Length | up to 160 characters | briefly | any |
| Useful for | time-sensitive, in person | Activation, Recall | Storytelling, Sequences |
| Not suitable for | Mass Email Newsletter | complex content | immediate response |
Frequency, Tonality, and Common Mistakes
A maximum of 2 to 4 text messages per month per recipient, a consistent sender name, and delivery times on weekdays between 10 a.m. and 7 p.m. are a safe bet. Common mistakes include sending messages too frequently, generic messages with no personal relevance, not providing an unsubscribe option, and using pushy phrases like „Last chance!“.
Anyone sending text messages as part of a loyalty program should obtain consent separately from other channels.

Conclusion
SMS marketing isn't the right channel for every message, but for the right messages, it's unbeatable. When used sparingly, personally, and clearly, SMS provides a direct line to customers that no other channel can deliver as reliably.
Appointment and reservation reminders, reward activations, and short-term promotions with clear instructions belong in text messages. Newsletters and general updates should remain in email and the app.
Frequently Asked Questions
How much does each text message cost in the DACH region?
Per SMS, unit costs typically range from about 5 to 10 cents, depending on the provider and volume. In addition, there are often small setup or platform fees. Compared to email or push notifications, SMS is thus significantly more expensive, but it’s often competitive on a per-message-viewed basis. A rule of thumb: If the value of a triggered action exceeds about €1, SMS is cost-effective in most cases.
Do I need separate consent for each channel?
Yes. Email, push notifications, and text messages are legally distinct channels and each requires explicit consent. In practice, a clear distinction during the onboarding process is helpful—for example, a separate question for text messages alongside the newsletter opt-in. A blanket “opt-in” box is legally vulnerable and leads to problems in the long run.
What should the maximum unsubscribe rate be?
A healthy SMS unsubscribe rate is well below 1 % per campaign. If it rises above that, you almost always have one of two problems: too high a frequency or too little relevance. Monitor the unsubscribe rate on a campaign-by-campaign basis; SMS responds very quickly. If you notice a notably high number of unsubscribes in your next mailing, either reduce the frequency or refine the content.
Are transactional text messages subject to the same regulations?
Transactional SMS messages—that is, messages triggered by a specific action—are not considered advertising and do not require separate consent for advertising. However, they must comply with data protection regulations, provide clear information at the time of data collection, and not include any mixed advertising content. As soon as an advertising message appears in an order confirmation, the message quickly becomes promotional.
What kinds of text message content work best?
Anything that’s time-sensitive and personal: appointment reminders with a confirmation option, reward activations, pickup notifications, and coupon reminders. General newsletters or brand storytelling without a specific deadline don’t work as well. Rule of thumb: If the message would also work in an email, it doesn’t belong in a text message.
Do I need a separate SMS tool, or can I do this through the loyalty system?
Both are possible. If you use a modern loyalty program, SMS is often integrated directly as a channel, triggered by the same events as push notifications and email. The advantage of this is that frequency limits and metrics remain consistent across all channels. A standalone tool can be useful if you use SMS solely for transactional purposes.
Does SMS marketing work internationally, too?
Yes, but with caution. Unit costs and legal requirements vary significantly from country to country. In the DACH region, SMS is used less frequently than in the U.S., for example, which means that an SMS has a greater impact here. When sending messages across borders, you should pay attention to country-specific opt-out rules and delivery times.
