The Ultimate Guide to SMS Opt-in for 2024 (Tips + Examples)

Sending unsolicited text messages to your customers is like barging into a party uninvited. It ticks people off, it’s illegal, and you’ll lose out on building a solid customer base. 

We understand that convincing people to share their numbers can be tricky, but the core of a successful SMS campaign is adhering to SMS opt-in best practices. You can gain trust and build a strong relationship with your audience by getting their explicit permission to send messages. It also reduces the chance of receiving spam complaints, leading to better and more positive customer experiences.

This article will tell you everything you need to know about using SMS opt-ins for your brand. 

What is SMS opt-in? 

SMS opt-in messages are requests for permission to send text messages to a user’s mobile device. These messages seek explicit consent, ensuring compliance with privacy regulations. Users must willingly agree to receive communications, promoting a respectful and legal approach to engaging with the audience through text messaging.

Your SMS opt-in process involves three key stages: 

  1. The opt-in mechanism: How customers request to receive your brand’s texts, often through web pop-ups, links in emails, or texting a specific keyword to your SMS code. 
  2. A confirmation message:  Prompts customers to text a keyword to verify their consent, creating a double opt-in, now the SMS marketing standard. 
  3. The initial text: Kicks off your official conversation, thanking subscribers, offering incentives, and introducing your brand.

Why is SMS opt-in important?

Permission-Based Marketing: Obtaining users’ permission before sending promotional messages shows respect for users’ privacy, which helps build trust and positive perceptions of the brand.

User Engagement: Opted-in users are more likely to engage with and respond positively to SMS messages, as they are genuinely interested in receiving communications from the business.

Relevance and Personalization: Enables businesses to tailor messages based on user preferences, making the content more relevant and engaging, capturing the user’s attention, and driving desired actions.

Reduced Spam Complaints: Ensures that messages reach the intended audiences, reducing the risk of users marking messages as spam as they have willingly opted to receive communications.

Cost-Efficiency: Optimizes marketing budgets by focusing on users who have expressed genuine interest.

Brand Image and Loyalty: Contributes to a positive brand image by demonstrating ethical and responsible communication practices.

Data Accuracy: Helps maintain accurate and up-to-date contact information as users are more likely to provide valid and current details during the opt-in process.

What are the SMS opt-in requirements? 

Let’s look into some of the important SMS opt-in requirements to be followed by businesses to follow compliances: 

Express Consent

Individuals must provide explicit consent to receive SMS communication from a particular sender. Consent is typically obtained through an opt-in mechanism, such as checking a box on a website, sending a keyword to a shortcode, or filling out a consent form.

Clear Disclosure

Double opt-in

This two-step process minimizes the risk of unintended subscriptions and aligns with privacy regulations; hence, this method is widely endorsed for its reliability in confirming user consent.

Ask your subscribers what they think! Getting feedback helps you understand what they like and what they don’t. This information is gold—it enables you to improve your messages and keep them interested.

What is SMS opt-out, and how do you control it?

SMS opt-out, also known as SMS unsubscribe or SMS opt-out compliance, refers to the process by which SMS recipients indicate they no longer wish to receive such messages. 

It’s a crucial aspect of SMS marketing to ensure that businesses comply with regulations and respect their customers’ preferences. It is also about building and maintaining a positive relationship with your audience. Respecting their preferences and providing an easy and transparent opt-out process contributes to a positive customer experience.

Here are the critical aspects of controlling SMS opt-out:

1. Clear opt-out instructions

Provide clear and easily understandable instructions on how recipients can opt out of receiving SMS. This often involves including a simple keyword or shortcode in the message, such as “STOP” or “UNSUBSCRIBE.”

2. Automated opt-out system

Implement an automated system that processes opt-out requests promptly. When a recipient sends the designated opt-out keyword, the system should automatically remove their phone number from the distribution list and confirm the opt-out.

3. Opt-out confirmation

Send a confirmation message to the individual who opts out, confirming their request has been received and processed. It helps build trust and assures that you respect their preferences.

4. Maintain a list

Keep a record of individuals who have opted out to create a do-not-contact list. Update and check this list regularly to ensure that those who have opted out are not accidentally contacted in the future.

5. Strategize for re-engagement

To re-engage users who have unsubscribed:

  1. Focus on showcasing the value they are missing out on.
  2. Offer exclusive discounts or promotions to entice their return.
  3. Share interesting content and sneak peeks of upcoming deals to get them excited again.
  4. Show them the unique benefits they’ll enjoy if they return to encourage re-engagement.
