Who can import a list? Shops on all Postscript plans have access to list imports. Learn more about Postscript Plans.
When migrating an SMS list to Postscript from Klaviyo, our team requires both a list of active subscribers and a list of unsubscribes (or inactive subscribers who were previously opted into your SMS program). By collecting both of these lists from your brand, you will:
- Ensure only active subscribers are added to your Postscript account.
- Avoid uploading inactive subscribers as a result of duplicate Klaviyo profiles with conflicting opt-in information.
- Hit the ground running with a compliant Postscript-hosted SMS program.
In this guide, we'll walk you through how to export both your active subscriber list and your inactive subscriber list.
Export Active Subscriber List From Klaviyo
- From your Klaviyo dashboard, select Lists & segments under Audience on the left-side navigation bar.
- Select Create List/Segment in the upper-right corner. Then choose Segment.
- Name your segment. Be sure to give it a name that will allow you to easily identify it among your lists and other segments when exporting.
- Under Definition, select the dropdown and choose What someone has done (or not done).
- Next to Has choose Subscribed to SMS Marketing. Then, select at least once and over all time as your following values.
- Select the + AND connector. Then, click the Select a condition... dropdown and choose What someone has done (or not done).
- Next to Has choose Unsubscribed from SMS Marketing. In the next dropdown to the right, select zero times and over all time as your following values. Note: At this time, take a screenshot of the criteria you've used. Our compliance team will request it from you later.
- Select Create Segment>> in the bottom-right of the editor.
- Once the segment is created, select Manage Segment in the upper-right corner, then choose Export Segment to CSV.
- Select the checkbox next to Property to select all. Once all of the properties are selected, choose Start Export in the upper-right corner.
- Once the export is complete, you can find this segment in your computer's Downloads file.
Note: Once we receive your uploaded list, our compliance team will email you to request proof of the criteria used when exporting active subscribers from your Klaviyo account. This is to ensure that the appropriate parameters were in place during the export in order to protect our customers from potential litigation.
Export Inactive Subscriber List From Klaviyo
- From your Klaviyo dashboard, select Lists & Segments under Audience on the left-hand navigation bar.
- Select Create List/Segment in the upper-right corner. Then choose Segment.
- Name your segment. Be sure to give it a name that will allow you to easily identify it as a list of inactive subscribers among your lists and other segments when exporting.
- Under Definition, select the dropdown and choose What someone has done (or not done).
- Next to Has choose Unsubscribed from SMS Marketing. Then, select at least once and over all time as your following values.
- Select Create Segment in the bottom-right of the editor.
- Once the segment is created, select Manage Segment in the upper-right corner, then choose Export Segment to CSV.
- Select the checkbox next to Property to select all. Once all of the properties are selected, choose Start Export in the upper-right corner.
- Once the export is complete, you can find this segment in your computer's Downloads file.
Import Active Subscriber List to Postscript
- Head to Postscript's Subscriber List Upload form.
- Fill out each required field. Attach your CSV from Klaviyo at the end of the form.
- Postscript's compliance team will review your list and upload it to your account in 1-3 business days. Once uploaded, you will be notified in-app and automatically see your subscribers added to your Postscript account.
Important! Do not upload your list of inactive subscribers to the Postscript List Upload Form. Please email the list to compliance-ops@postscript.io.
Before You Go
- We highly encourage you take screenshots and/or photos of your opt-in forms with compliance language present so you can continue to keep your subscriber collection records should you need to reference them in the future.
- Before exporting your list to upload to Postscript, be sure to deactivate list growth tools (popups, keywords, landing pages, etc.) on Klaviyo so your list exports are comprehensive and as up-to-date as possible ahead of the migration.
- Once you're migrated to Postscript, activate Postscript list growth tools (popups, keywords, landing pages, etc.) to begin subscriber acquisition.
