With an impressive 95% open rate and instant impact, SMS marketing is one of the most powerful communication channels for capturing your audience's attention, converting, and quickly building customer loyalty.
Yet, many businesses miss out on its true potential by making common mistakes that hinder their campaign performance.
In this article, discover the most frequent pitfalls, as well as strategies to convince your customers to subscribe to your offer or buy your products, and thereby reach your marketing goals.
Common mistakes to avoid
1/ Forgetting the call-to-action (CTA)
Description:
A common mistake is forgetting to add a compelling call-to-action. This element is essential for guiding your recipients on what to do after reading your message. You simply cannot afford to skip it!
Here are a few examples of actions:
- Buying a product;
- Subscribing to service offers;
- Making a reservation;
- Completing a survey;
- Registering for an event;
- Etc.
The CTA usually takes the form of a clickable link that directs users to a specific page, such as a website, an offer, or a form.
Consequences:
Without one, your messages risk lacking clarity and failing to motivate your targets to move further along the journey.
Because if you don't give them clear instructions, your customers won't know what they are supposed to do.
This can even frustrate them, thereby increasing the risk of unsubscribes or indifference toward your future messages…
Solution:
Make sure to include a clear and engaging CTA as a clickable link.
Here are a few concrete examples:
- "Book now";
- "Discover our offer";
- "Explore our selection";
- "Reply YES to take advantage of this".
Ensure it redirects the user directly to an optimized page to encourage them to take action quickly.

2/Not personalizing your messages
Description:
Sending generic messages without any personalization can quickly make your customers feel like just another number. They won't feel valued at all, which is a missed opportunity.
Keep in mind that personalization goes beyond just including the recipient's first name; it’s primarily about tailoring content based on their preferences, shopping habits, or location.
Consequences:
Standard, non-individualized content will generate a lack of interest and engagement from your target audience, which will unfortunately result in low click-through and conversion rates.
It can even annoy your customers, prompting them to ignore your future messages or unsubscribe.
Solution:
Use all the data at your disposal to personalize your SMS.
Integrate not only your contact's first name but also recommendations based on their preferences or purchase history.
For example: "Hi Julie, check out our selection of new coats just for you!"
Smart personalization shows your audience how much you value them, which will consequently increase your chances of capturing their attention and building a genuine connection.
3/Sending messages that are too long or poorly written
Description:
Even if you offer the most attractive deals, if your message isn't impactful, your campaign won't get the engagement you expect.
Remember that your customer is reading your SMS on a small mobile screen, not on a computer. You must therefore ensure you are as clear and understandable as possible for better readability.
Every word counts to convey the right intent and encourage them to take action.
Consequences:
Texts that are too long and convoluted phrasing risk losing your target's attention and damaging your credibility.
You will see a low read rate and a lack of interest from your recipients.
Solution:
Write short sentences with simple words for clear and concise messages. Always get straight to the point and favor lively phrasing for greater impact.
For example: "Get 20% off the entire store! Click here to claim your discount before tonight: [link]".
Don't hesitate to test your messages with A/B testing to determine which version is the most impactful.
4/Not complying with SMS marketing regulations
Description:
Sending SMS is subject to strict regulations that protect consumers. This is why any company wishing to launch campaigns must first obtain the recipients' consent and provide an opt-out option.
These rules are designed to protect consumers against intrusive practices and ensure ethical and transparent communication.
Consequences:
Failure to comply with regulations can lead to heavy fines and seriously damage your company's reputation. Furthermore, non-consenting recipients are more likely to report your messages as spam, which can affect your future campaigns and undermine trust in your brand.
Solution:
Comply with laws such as the GDPR (General Data Protection Regulation).
Ensure you obtain explicit consent before sending SMS, always provide a clear opt-out option, and manage your target audience's personal data securely.
Compliance strengthens your customers' trust in your business.
Best practices for effective communication
Scheduling SMS campaigns
In marketing, as you know, it is always crucial to send the right message at the right time, because even the most interesting content in the world can lose all its impact if it is sent at an inappropriate time or one that simply does not align with your recipients' habits.
To ensure your campaigns are successful, schedule your SMS messages by choosing an appropriate time.
In France, please note that you are not permitted to send SMS:
- Between 8:00 PM and 8:00 AM
- On Sundays
- On public holidays
In any case, for maximum impact, send your messages when your audience is receptive.
For example, a promotional SMS sent at 11:00 PM risks being ignored or perceived as intrusive by your customer, whereas a message scheduled just before their lunch break is more likely to encourage them to take action.
A/B testing to improve your performance
A/B testing is an essential strategy for improving the performance of your SMS marketing campaigns. By comparing two versions of a message on a sample of your audience, you can identify exactly what works best to capture attention, generate clicks, and increase conversions.
How does it work in practice?
1. Create two variations of your SMS
For example, you can test two different calls to action:
"Discover the offer" or "Buy now."
You can also vary the tone, the length of the message, or even the time of sending.
2. Send each version to two distinct groups
Select a customer segment, such as loyal customers. Divide this segment into two equal groups to ensure comparable results.
Send both versions of the message simultaneously to the two defined groups.

3. Analyze the statistics
Finally, compare open, click-through, or conversion rates to determine which version performs best, and select it for your future campaigns.

Performance tracking is an essential step.
Skipping this step means navigating completely blind, without knowing if your messages are hitting their mark or where you need to take action.
