10 tips to write compelling sales texts for SMS marketing

10 tips to write compelling sales texts for SMS marketing

SMS messages are read more frequently than other forms of marketing communications. According to a study by SHIFT agency, four out of five smartphone owners open every SMS they receive.

One of the main advantages of SMS marketing is that customers can store important information in their phones for a long time and have access to it at any moment. A successful SMS marketing text begins with addressing the customer’s pain point, making it clear from the first lines that the message is about them. Then, it goes straight to the essence of the offer without unnecessary details and includes a call to action.

In this article, we’ve compiled 10 basic principles to help you write “selling” SMS messages — useful and unobtrusive ones that will motivate customers to make purchases. The foundation of the article is based on our own experience, as well as research from American and European messaging services and agencies.

№ 1: Make specific offers

Don’t waste users time and write SMS messages as succinctly and specifically as possible so that it’s clear from the first words what the offer is about.

Wrong

A specific offer is hidden in abstract words and is not obvious

Correct

The SMS immediately promises clear benefits.

№ 2: Respect the recipient

    You should know a few basic rules:
      1. Do not use capital letters throughout the message — it’s the visual equivalent of shouting.
      2. Do not overuse exclamation and question marks — in the text, they look like cries of desperation.
      3. Do not overuse emojis in messages — AB tests by 12 STOREEZ have shown that SMS messages without emojis are opened much more often.
Wrong

SMS in capital letters looks aggressive, as if shouting at the recipient.

Correct

An example of successful use of capital letters in an SMS text.

№ 3: Choose the right time to send

According to Textmagic, for event-related messaging, the best time to send is closer to the event time, as SMS messages are read almost immediately.

Wrong

Such messaging on a Friday evening may be ineffective, as many customers may already have plans for the weekend.

Correct

The SMS specifies the actions more clearly and is sent on Thursday evening so that customers have the opportunity to take advantage of the offer by the beginning of the weekend.

№ 4: Do not send SMS every day

Be mindful of the frequency of your SMS campaigns. This is crucial for budget savings and maintaining customer loyalty. Studies show that SMS spam can trigger a negative reaction

It’s best to use mass messaging selectively, only for major events and promotions. For example, a report from the SimpleTexting messaging service indicates that the main reason customers opt out of SMS campaigns is because the company reminds them too frequently.

In a survey about how often customers are willing to receive SMS messages from companies, 56% responded every two weeks, 29% once a week, and only 2.3% four times a week.

№ 5: Limit the duration of special offers

Limiting the duration of an offer makes it more desirable for customers. This triggers a Black Friday effect – customers feel they might miss out on a great opportunity, so they respond faster.

Wrong

Discount not time-limited, so offer seems uninteresting

Correct

SMS with limited-time offer

№ 6: Send SMS from a recognizable sender name

If you specify the sender’s name in your SMS campaigns, it will generate more trust from your customer base. Research shows that customers usually ignore messages from unknown senders as they consider them unwanted advertising.

Wrong

Unknown number does not inspire trust

Correct

The recipient knows who the SMS is from and is more likely to open it: from Golden Apple

№ 7: Call to action

Calls to action in SMS campaigns increase the likelihood of conversion. You can ask customers to register, send a message, or use a coupon. If a message lacks a clear call to action, customers are more likely to ignore it, even if the content interests them.
Wrong

Unclear what the SMS means and what the company expects from the customer

Correct

Clear call to action and direct link in SMS

№ 8: Prepare the mobile version of your website

Avoid sending customers links that require printing or redirecting to a non-optimized mobile version of the site. If consumers need to enter a login and password, consider using social networks for logging in, such as Facebook, making it easier for customers and providing you with additional user data.

Wrong

Without a mobile version of the website, your offer is likely to be ignored

Correct

A user-friendly interface can build strong connections between the company and the customer

№ 9: Make different special offers

Diversity in special offers helps maintain customer interest in SMS campaigns. According to recommendations from Simpletexting, companies can offer various promotions and discounts to attract customer attention.

For example, one week you can offer a discount on products, the next – a promo code for an additional discount, and then – invite customers to a fun event or promotion.

Diverse offers help maintain customer interest and activity.

№ 10: Keep SMS under 70 characters

The maximum length of one SMS is 160 symbols. If you exceed this limit, the system perceives it as multiple SMS, which can increase marketing expenses. Therefore, it’s important to write short messages.

We advise you to use the “inverted pyramid” principle: start the SMS with the main idea, followed by additional information.

Wrong

Example of a long SMS that may not be read in most cases

Correct

Example of a short and concise SMS

In conclusion

We’ve provided you with several examples of strong sales texts for SMS campaigns. But you must remember that there is no perfect formula – the effectiveness of promotions needs to be tested. And it’s best to do this with a full arsenal of tools for comfortable SMS marketing.
