Why Use Postscript Opt-in Links

  2. Locate and select the mobile popup you wish to edit.
  3. Select the call-to-action button to populate the Button Click Action side menu.

  5. In the Destination URL field, enter or paste the URL you copied from Postscript.

Compliance Language Requirements


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.

Since your opt-in process will auto-populate a message draft in your subscriber's phone, your popup must display proper TCPA compliance language.

Here's the TCPA-approved compliance language:

*By providing your phone number, you agree to receive recurring automated marketing text messages (e.g. cart reminders) from this shop and third parties acting on its behalf. Consent is not a condition to obtain goods or services. Msg & data rates may apply. Msg frequency varies. Reply HELP for help and STOP to cancel. You also agree to the Terms of Service and Privacy Policy.

Note: In order to collect subscribers compliantly, your shop's Terms of Service and Privacy Policy need to be hyperlinked in the language shown above. If they cannot be hyperlinked, the full URLs of each need to be included so a viewer may search your terms or privacy policy if needed.

For example, "View our Terms of Service (https:/myshop.com/terms-of-service/) and Privacy Policy (https://myshop.com/privacy-policy/).”
