Growing your subscriber list is an essential part of a strong SMS strategy, and Postscript offers several creative ways to add SMS list growth opportunities throughout your marketing efforts.

In this article, we are going to introduce growing your list using an opt-in link.


When visitors or customers select the link, they're taken to a Shopify landing page where they can enter their phone number and complete the SMS opt-in process.

You can include an opt-in link on your website, in emails, and in social media campaigns. Here are some popular examples:

  • Promote a giveaway in an email and link readers to the landing page for entry.
  • Direct Instagram followers to the opt-in landing page with a swipe-up story.
  • Offer time-sensitive discount codes in social advertisements and link to the landing page.
  • Use different opt-in links to track the success of different traffic sources.

  1. Select Acquisition in the side menu of your Postscript dashboard, then select List Growth Tools.
  2. Locate Share your opt-in link and select Get Started to the right of this option.
  3. Choose a Keyword from the drop-down. We recommend you choose a keyword with a coupon associated with it. Users who opt-in using this link will be logged under this keyword.
  4. Select Create Page to create a landing page where desktop visitors can enter this phone number. Postscript will provide the necessary compliance language here.
  5. Proof your Mobile Opt-In Message. When users on a mobile device select your opt-in link, it will launch their native mobile app with this message pre-populated.
    • If your keyword is identical to the shop name included in your message, your link creation will error out. Please use a keyword that is not your exact store name.
  6. Select Get Link to generate the opt-in shortlink. 

Don't forget to copy your compliance language at the bottom of the page. If you are sharing the link in places where users are most likely on their mobile device (i.e., Instagram), you will need to include this language as they will not be directed to the compliant landing page.

Alternatively, you can always create a dedicated landing page that will ensure identical opt-in experiences for both your mobile and desktop subscribers.

Include Compliance Language


When collecting subscribers, the TCPA requires you to include necessary compliance language that informs visitors that they are opting into SMS messaging from your store.

Here's the TCPA-approved compliance language:

*I agree to receive recurring automated marketing text messages (e.g. cart reminders) at the phone number provided. Consent is not a condition to purchase. Msg & data rates may apply. Msg frequency varies. Reply HELP for help and STOP to cancel. View our Terms of Service and Privacy Policy.
You should be all set to begin growing your subscriber list with an opt-in link and landing page!
