For those looking to add mobile messaging to their marketing stack or increase the efficiency of their subscriber list, Justuno has a new feature to help do just that. We’re excited to announce a new SMS call-to-action (CTA) layer on mobile promotions that can help you quickly collect subscribers using a two-step opt-in that efficiently scales your SMS marketing database. This new SMS opt-in feature is being called “tap-to-text.”

SMS Opt-in Promotion

How The SMS CTA Layer Works

If you have an SMS provider, you can now use Justuno to collect even more subscribers using a simple CTA click exclusively in mobile SMS pop ups.

Note: This feature only works with mobile promotions, the layer simply won’t appear if placed on a desktop promotion

Rather than having potential subscribers take the time to enter their phone number and then wait to receive a text from you, using this SMS CTA layer will streamline the process.

When a mobile visitor is served a promotion asking them to opt-in to mobile messaging, they’ll simply have to click the CTA for “Yes.” This click opens the SMS (texting) app on their phone, with a pre-filled message ready to send to the phone number/short code provided by your SMS software. All they have to do is hit send, and they’re opted-in.

SMS Subscriber Flow

Use Justuno’s SMS integrations with SMSBump, Postscript, or Retention Rocket to help set up the opt-in text with desired next steps, like sending a reply message with a discount or automatically adding them to a list or automated marketing flow.

For step-by-step instructions to set this up in your Justuno account, check out the support article.

Creating Growth

Using the SMS CTA layer is a powerful way to power growth due to the simplicity of opting-in- all users have to do is tap twice rather than type out a submission. This ease of use is key for mobile traffic, where users are typically on the go and the quickest to abandon. In the world of instant-gratification, whoever is quickest often wins.

Looking to go even further? Combine the SMS CTA layer with a multi-screen two-step promotion to collect email addresses as well as SMS opt-ins for an easy two-for-one win. 

Email and Text Opt-in Promotion

Let’s check out a few best practices from our SMS providers for maximum effectiveness:

SMSBump (now a Yotpo company)

For those looking to collect phone numbers early in the customer journey, SMSBump recommends mixing eye-catching pop-ups with text opt-ins for an average of 5% or higher conversion rate. 

This is a super simple way to utilize the new SMS CTA layer within your Justuno pop-ups to collect mobile subscribers and streamline the opt-in process.

Don’t limit your SMS collection efforts to your website, SMSBump recommends utilizing your social media followers for quick wins. Use keyword opt-ins or shareable links for followers to sign up to receive texts wherever they are. That being said, make sure to also utilize one of the most natural touchpoints with your customers – your e-com checkout page. SMSBump users who leverage opt-ins directly at checkout see over 45% higher mobile subscriber rates.

For Postscript, they have only two requirements:  the text must include the keyword and that the keyword is in all caps. Pretty simple! For any questions, you can refer to step six in this article when linking your Postscript account with a Justuno promotion.

Retention Rocket

Retention Rocket has a few tips for getting started, first off that you make sure the user has confirmed their mobile device by either sending a message or replying with “Yes” to a message you sent them. Second, make sure you inform the subscriber how they can opt-out and send compliance information such as how often messages are sent, that messaging and data rates may apply, terms, etc.


Klaviyo encourages its users to keep in mind what is included in the message body, specifically, that the opt-in message includes the keyword “Join.” This is key for their platform, so a customer who clicks the button and sends the text will be subscribed to texts as long as your opt-in message clearly states their consent using this trigger word.

Final Thoughts

This new feature is a great way to start collecting mobile SMS opt-ins in the most efficient way possible. As SMS marketing only continues to grow in popularity and ROI, it’s critical to start building your database and engaging with customers where they want.
