A/B testing for SMS marketing: How to Get the Best Results for Marketing Campaigns

July 31, 2024

Marketing campaigns are vital for businesses, especially in the competitive landscape of e-commerce. 

Yet, many campaigns fall short due to a lack of targeted and optimized strategies. One effective method to refine and improve your campaigns is A/B testing. 

This article delves into A/B testing for SMS marketing, offering insights and strategies to achieve the best results for your campaigns.

What is A/B Testing for SMS Marketing?

A/B testing of SMS marketing is a method of comparing two versions of an SMS marketing campaign to determine which one performs better. By sending different messages to segments of your audience, you can analyze which variant drives more conversions, engagement, or any other desired action.

11 Conversion-Driven Types of A/B Testing

Before diving into specific types of A/B testing for SMS marketing, it’s important to understand the foundational value of these experiments. 

A/B testing allows you to isolate and test individual elements of your messaging strategy, providing clear insights into what drives user engagement and conversions. 

By systematically comparing different variations of your SMS campaigns, you can fine-tune your approach to resonate more effectively with your target audience. 

Here are some of the key types of A/B tests you can implement to optimize your SMS marketing efforts:

1. Image-Based with Content

This type of testing compares SMS messages that include images (via MMS) against text-only messages. 

For example, a restaurant might send one group a text message describing a new dish and another group a message with an image of the dish. By analyzing engagement rates, businesses can determine if visual content boosts conversions.

2. SMS with MMS

Beyond image comparisons, testing SMS versus MMS involves assessing the impact of multimedia elements, like videos or gifs, in messages. 

For instance, a fashion retailer could test plain text sale notifications against MMS messages showing models wearing discounted items. The richer multimedia content might lead to higher engagement and conversion rates.

3. Emoji Driven for Gen-Zs

Emojis can add personality and emotional appeal to messages. A/B testing with and without emojis can reveal their impact on engagement, especially among younger audiences. 

A clothing brand might test a message saying, “Big Sale Today!” against “Big Sale Today! 🎉” to see which one resonates more with Gen-Z shoppers.

4. Short and Large Content Format

The length of your SMS content can significantly impact readability and engagement. Testing short, concise messages against longer, more detailed ones helps identify the optimal length for your audience. 

For example, a tech company might test a brief announcement of a product launch against a detailed message explaining features.

5. Customer Journey Focused

Testing different messages tailored to stages in the customer journey—like awareness, consideration, and decision—can enhance relevance and effectiveness. 

A beauty brand could compare the results of an introductory offer message sent to new subscribers against a loyalty reward message sent to returning customers.

6. Incentive-Based Testing

Offering various incentives such as discounts, freebies, or early access can be tested to see what drives more conversions. 

For example, an electronics retailer might A/B test a message offering a 10% discount versus one offering a free accessory with a purchase.

7. Call to Action Variation

Different calls to action (CTAs) can dramatically affect the performance of your messages. 

Testing CTAs like “Buy Now,” “Learn More,” or “Sign Up Today” helps identify the most compelling prompts. 

An online bookstore could test “Shop Now” versus “Browse Our Collection” to see which drives more clicks.

8. Copy Variation Based on Demographical Audience

Tailoring your message copy to different demographics can optimize relevance and engagement. 

For instance, a fitness brand might test messages highlighting health benefits for older audiences against those emphasizing appearance for younger ones.

9. Tone of Voice Variations for Different Generations

The tone of your message—casual, professional, or playful—can impact how different age groups receive it. A/B testing can help determine the best tone for each segment. 

For example, a bank might test formal language for older customers and a more relaxed tone for younger clients.

10. AM vs PM Testing

The timing of your SMS campaigns is crucial. Testing messages sent in the morning versus those sent in the evening can reveal optimal times for engagement. 

A travel agency could test sending trip deals at different times to see when customers are more likely to book.

11. Discount vs Promotion

Comparing the effectiveness of straightforward discounts against promotional offers can help refine your incentive strategy. 

A beauty salon might test a 20% off message against one offering a free service with a booking to see which drives more appointments.

Laws to Follow in A/B Testing (as of 2024)

Compliance with regulations is essential in SMS marketing. As of 2024, marketers must adhere to the Telephone Consumer Protection Act (TCPA), ensuring they have explicit consent from recipients. 

Messages should include opt-out instructions, and businesses must honor opt-out requests promptly. Additionally, the General Data Protection Regulation (GDPR) may apply if marketing to EU residents, requiring specific consent and data protection measures.
