   Tip: Select any of the images or GIFs in this article for a closer look.

Postscript popups continue to be a powerful (and compliant) way to collect SMS subscribers. But did you know that in addition to collecting phone numbers, you can also configure your Postscript popup to collect email? And if you have an active Klaviyo integration, you can send that email data to Klaviyo.

How Sending Subscriber Email Data to Klaviyo Benefits You

  • Simultaneously build your SMS and email subscriber list with a single popup.
  • Assign subscribers to a particular Klaviyo list for later use in Klaviyo email campaigns.

Configure Postscript to Send Email Data to Klaviyo


  1. Select Acquisition in the side menu of your Postscript dashboard.
  2. Select the popup that you'd like to forward emails from to Klaviyo.
  3. Under the popup name, select the + Add Step/Custom Step tab. When you select + Add Step, you are able to add an additional step for subscribers to enter their email address. Alternatively, you can also use this second step to collect custom properties.
  4. When collecting emails, you can toggle the Forward to email app option ON and select which lists hosted by your email servicer provide you'd like to forward the collected emails to.
