Postscript integrates with Klaviyo, allowing you to share information between the two solutions.

About Klaviyo

Klaviyo is an automated marketing campaign solution that focuses on email, social advertising, and analytics. By linking your Klaviyo account with Postscript, you can grow your SMS subscriber list through Klaviyo forms, popups, and email lists.

How Do Klaviyo Lists Work?

Klaviyo lists allow you to organize subscribers who opt-in via a specific popup or form. When you create a popup or form in Klaviyo, you assign a list to the modal.

Once someone opts-in using that form or popup, they are added to the assigned Klaviyo list and flow through to Postscript.

Note: You will need to set up your Klaviyo integration before numbers can flow through to Postscript. Learn more about the setup process here.

When Does Postscript Sync Klaviyo Data?

Postscript pulls two types of information from Klaviyo: lists and subscriber information. Check out the tabs below to learn more about the specific sync times for each.

Postscript syncs newly created Klaviyo lists nightly.
- Example: Today you created a new Klaviyo list that you assigned to a popup where subscribers can sign up for early access to an upcoming new product drop. Since the list is brand new, it will not show in Postscript until the following morning. Any subscribers who sign up between now and then will appear with the list the next morning.
Postscript syncs data for existing Klaivyo lists every fifteen minutes.
- Example: You re-activate an opt-in form assigned to your "New Subscribers" list in Klaviyo. Since this list has been used before, it is already in Postscript. Postscript will sync any new subscriber data from this list every fifteen minutes.

Postscript syncs subscriber data every fifteen minutes.
- Example: A website visitor opts into SMS marketing using a giveaway Klaviyo popup. You created the popup (and the list) last week, so it already exists in Postscript. This new subscriber's data will show in Postscript during the next fifteen-minute sync time. Once synced, they will pull into any segment created from the Klaviyo list and will be searchable in Postscript.

Exception: New and existing subscribers will sync for a new Klaviyo form once the new form has synced in Postscript (which is done nightly). Once the list is in Postscript, any subscriber updates will happen every fifteen minutes.
