Its great advantage lies in immediacy and in the high open rates, far superior to other traditional channels.

This type of marketing allows you to send key information in seconds, whether a promotion, a notification or a reminder. Being such a personal and accessible channel, it achieves a direct connection with the user, something brands increasingly value.

In addition, SMS marketing stands out because it is simple, cost effective and universal. It does not depend on external applications, does not require an internet connection and works on practically any mobile device, which makes it highly inclusive.

In this article we will see what it is, what its advantages are and how to integrate it within a modern communication strategy to make the most of its potential.

9 key points to understand text message marketing

1. Clear definition: what it is and how it is used in modern businesses

Text message marketing consists of sending short and direct communications to customers through SMS.

Its use goes beyond simple promotions, today it is applied in appointment reminders, order tracking or loyalty campaigns, becoming an essential tool in customer management.

Its value lies in the immediacy and closeness it offers, since the messages arrive directly to the mobile device, without intermediate filters or the risk of getting buried in saturated inboxes.

2. Difference compared to other channels: email, calls, WhatsApp

Unlike email, which often gets lost in the promotions folder, or calls, which can be perceived as invasive, SMS has immediate reach and a more positive perception from users.

Even compared to WhatsApp or other messaging apps, text messages stand out for their universality, they work on any phone, with no need for internet or additional downloads.

3. Higher open rates: why SMS stands out over email

SMS campaigns far outperform email in open rates, which can reach over 90% in just minutes.

This makes text message marketing one of the most effective channels to ensure that the message is actually read.

In addition, its brevity encourages immediate action, with a well designed link or call to action, the impact is almost instant.

4. Practical examples: how an SMS after a meeting speeds up closing

Imagine that a salesperson has just finished a meeting with a client. 

Sending a short and personalized SMS with a reminder of the proposal or with a link to the contract can speed up the purchase decision and help improve sales prospecting.

In the same way, a text message after a support call can improve customer satisfaction, by showing follow up and commitment.

5. Productivity in action: automated messages that save time

Automated SMS marketing allows you to schedule mass or individual sends at key moments.

This frees teams from repetitive tasks and ensures that communication always arrives on time.

Automated flows are ideal for sending payment reminders, delivery notices or limited offers, optimizing the productivity of sales and support teams.

6. More data for the CRM: each interaction is recorded in a structured way

Every SMS sent and received becomes a valuable piece of data for the company.

By integrating it into the CRM, a more complete view of the customer journey is obtained, allowing better segmentation and personalization of communication.

This structured record facilitates more detailed later analysis, improving strategic decision making and the return on investment in marketing.

7. Omnichannel as a competitive advantage: integrating text messages with calls, email and chat

The true potential of SMS emerges when combined with other channels.

An omnichannel strategy allows a customer who receives an SMS to continue the conversation by email, call or chat, without losing context.

That integration offers a fluid and coherent experience, increasing customer trust and multiplying conversion opportunities.

8. Relevance in marketing and sales: immediate reach and precise segmentation

SMS marketing not only guarantees visibility, it also allows the segmentation of audiences based on interests, purchase history or location. This ensures that each message is relevant and reaches the right audience.

In sales, this personalization capability translates into faster closings and communication perceived as useful, not intrusive.

9. Industry trends: how messaging evolves in digital marketing strategies

The future of text message marketing is oriented toward smart automation and artificial intelligence integration to create more personalized experiences.

Companies no longer see it as an isolated channel, but as part of a broader digital strategy, where it coexists with email, social media and chatbots.

Its evolution points to reinforcing brand omnipresence, ensuring faster, more relevant and effective interactions.

5 Key benefits of text message marketing for your company

1. Direct connection with customers

Text message marketing guarantees immediate and personal communication.

Unlike other channels, SMS arrives directly to the customer’s device, which increases the probability of being read in just minutes.

This close contact helps create a stronger and more reliable relationship, delivering clear messages without depending on saturated inboxes or the customer’s availability to answer calls.

2. Greater speed in campaigns

One of the great advantages of SMS is its speed of delivery and reading.

Sending a promotion, a reminder or a service notification through this channel ensures an almost instant reaction.

This allows companies to make better use of time in sensitive campaigns, such as flash sales or urgent notices, where speed makes the difference in conversion.

3. Scalability for sales and marketing

SMS marketing is highly scalable, it adapts both to small campaigns and to mass sends without losing effectiveness.

A small business can use it to build customer loyalty, while a large company uses it to coordinate promotions in multiple markets.

Its low cost and ease of implementation make it an ideal option for companies seeking to increase their reach without large additional investments.

4. Closer customer experience

Text messages bring a personal touch that other channels do not always achieve.

A customer who receives an SMS with their name or with information relevant to their situation perceives greater care and attention from the brand.

In addition, omnichannel gains strength when SMS is combined with email, calls or chat, creating a coherent and more human experience at every point of contact.

5. Generation of more data for better decisions

Each interaction via SMS leaves a structured record that can be analyzed to improve commercial and marketing strategies.

Open rates, link clicks or conversions make it possible to better understand customer behavior.

When integrated into a CRM, this data provides a more complete view of the customer journey, which facilitates segmentation, personalization of future campaigns and smarter business decisions.

4 Types of text message marketing campaigns

1. Exclusive promotions and discounts

Promotional SMS are one of the most common uses of this channel. By sending limited offers or exclusive coupons, companies generate urgency and immediate motivation in the customer.

This type of message has a direct impact on sales, especially on key dates such as sales, Black Friday or seasonal campaigns.

The brevity of SMS forces clarity and directness, which increases the probability that the customer will act at the moment.

2. Appointment or booking reminders

The sending of automated reminders via SMS reduces no shows in medical appointments, restaurant reservations or professional services.

It is an ideal channel because it arrives directly to the phone and does not require the customer to check their email.

This use increases operational efficiency of the company and improves the customer experience, by offering them a useful and timely reminder.

3. Satisfaction surveys and immediate feedback

With a short message and a link to a survey, companies can obtain valuable opinions in real time. This helps measure service quality and detect improvement opportunities faster than with traditional methods.

In addition, the SMS format gives the customer the feeling that their opinion is quick to give and really taken into account.

4. Transactional messages (shipping, confirmations, payments)

Transactional SMS inform about order status, purchase confirmation or payment validation.

They are essential in e commerce and subscription services.

By keeping the customer informed at every step, trust in the brand is strengthened and the need for inquiries in other service channels is reduced.

Strategies to increase the effectiveness of your SMS

Personalize with the customer’s name and preferences

A generic message may go unnoticed, but a personalized one generates a stronger connection. Including the customer’s name or references to previous purchases increases relevance and response rate.

Personalization turns SMS into a close channel adapted to each user.

Segment the audience for more relevant messages

Not all customers need to receive the same information. Segmentation by interests, purchase history or location allows you to send more specific and valuable messages.

This practice improves the customer’s perception, since they receive offers tailored to what really interests them.

Include clear and easy to follow calls to action

Each SMS must have a specific objective: visit a link, confirm an appointment or redeem a coupon. That is why it is key to include a clear, short and easy to execute call to action.

A button, a short link or a simple instruction makes the difference in the effectiveness of a campaign.

When and how to send effective text messages

Recommended times to maximize open rate

The moment of sending directly influences the effectiveness of a campaign.
The best times are usually mid morning or early afternoon, when users are more receptive and attentive to their phone.

Avoiding early mornings, nights or holidays helps ensure that the message is not perceived as an annoyance and, at the same time, increases the probability of immediate reading.

Proper frequency: do not saturate the customer

Sending messages constantly can tire the user. That is why it is essential to find a balance between presence and excess.

The recommendation is to prioritize relevance over quantity, sending only when the message provides real value.

Moderation builds a longer lasting relationship, based on trust and respect for the customer.

Adjusting content according to the purchase cycle

Not all customers are in the same stage.

A new user may need introductory information, while a repeat one will respond better to exclusive promotions or reminders.

Adapting messages to the moment of the purchase cycle allows you to offer more useful content and increase conversions without seeming intrusive.

Integration of text message marketing with other channels

Combine SMS with email campaigns

SMS can act as the perfect complement to email. While email allows you to expand details, SMS provides immediacy and reminder.

An effective example is announcing a promotion by email and sending a short SMS just before it ends, reinforcing urgency and generating more conversions.

Coordinated use with calls and WhatsApp

The strength of SMS is multiplied when integrated with other communication channels. 

After a call, a confirmation SMS can consolidate the agreement. Tools such as an automatic call dialer further streamline this process by reducing manual effort.

In the case of WhatsApp, both channels offer an omnichannel experience, ensuring continuity in the conversation regardless of the medium.

This coordination improves the relationship with the customer, by conveying consistency and constant attention.

Multichannel strategies to improve conversion

The real power of digital marketing lies in the multichannel strategy.

Combining SMS, email, calls and instant messaging allows you to reach the customer in the most convenient way at any given moment.

This integrated approach offers greater reach, personalization and effectiveness, generating a smooth journey that increases conversion rates and strengthens brand loyalty.

4 Key metrics to measure the success of your SMS campaigns

1. Open rate

The open rate measures how many recipients read the received messages.

In SMS, this metric usually exceeds 90%, making it one of the most effective channels compared to other media such as email.

A high level of opens ensures that the message was not only delivered, but also captured the customer’s attention in minutes.

2. CTR (click through rate) in links

CTR indicates the percentage of users who clicked a link inside the message. This data reveals the persuasive capacity of the content and the relevance of the offer.

Well structured SMS, with a short link and a clear call to action, usually achieve click rates between 10% and 30%, far above other digital channels.

3. Conversion rate and sales generated

Measuring how many customers complete the desired action, whether a purchase or a registration, is essential to calculate return on investment (ROI).

SMS campaigns with precise segmentation and personalized messages achieve high conversion rates, consolidating their role as a sales and loyalty channel.

4. Unsubscription rate

The opt out rate reflects the percentage of users who decide to unsubscribe from the list.

A sudden increase may indicate that the messages are too frequent, irrelevant or sent at inappropriate times.

Analyzing this metric allows you to adjust the strategy to maintain an active and engaged contact base.

Regulation and best practices in SMS use

Explicit user consent (opt in)

Before sending any message, it is mandatory to obtain explicit permission from the customer. This consent guarantees compliance with the law and reinforces trust in the brand.

A transparent opt in avoids legal problems and improves the perception of the company as respectful and trustworthy.

Clear options to unsubscribe (opt out)

Every SMS must include an easy way for the customer to unsubscribe at any time. It can be a direct link or a keyword such as “STOP”.

Offering this option protects the brand’s reputation and shows commitment to user experience.

Compliance with regulations such as GDPR

In Europe, the General Data Protection Regulation (GDPR) requires companies to handle personal data securely and transparently.

This includes keeping records of consents, ensuring data deletion upon request and applying security measures.

Complying with these regulations not only avoids penalties, it also contributes to a stronger and more ethical relationship with customers.

Common challenges when using text message marketing

Initial resistance from teams

One of the main challenges is resistance to change.

Teams used to relying on calls or emails may perceive SMS as a secondary channel.

To overcome it, it is necessary to show its real impact on sales and loyalty, highlighting the speed and effectiveness of messages.

Integration with existing tools

SMS marketing must work coherently with the rest of digital tools.

When there is no good integration, time is lost in manual records and database management.

The key is to choose solutions that allow connecting the SMS channel with CRMs and marketing platforms, avoiding information silos.

Legal and regulatory compliance

Complying with regulations such as GDPR or LOPD GDD is essential.

Not having explicit user consent or not offering a clear unsubscribe option can lead to penalties.

Therefore, each campaign must be designed within a legal framework that protects both the customer and the company.

Best practices for implementing text message marketing

Personalization of messages

A generic SMS has less impact than one tailored to the customer.

Including the name, references to past purchases or specific benefits makes the message more relevant and close.

This personalization increases interaction and loyalty.

Use of automations and templates

Automations allow scheduling reminders, promotion sends or purchase confirmations at the right time.

Using optimized templates guarantees consistency in communication, saving time and reducing human errors.

Coordination with other channels (calls, WhatsApp, email)

The true value of SMS is enhanced when integrated into an omnichannel strategy.

Coordinating messages with calls, WhatsApp or email offers the customer a smooth and uninterrupted experience, strengthening the brand’s presence at all points of contact.

Measuring results with clear KPIs

Without proper measurement, it is impossible to improve.

Defining KPIs such as open rate, clicks, conversions and unsubscribes makes it possible to understand what works and what does not.

This data is essential to optimize campaigns and ensure that each send provides measurable value to the business.
