First Purchase flow back population

Back-populating profiles into a date-triggered flow in Klaviyo, like your First Purchase Anniversary Flow, can be tricky because Klaviyo doesn’t allow retroactive triggering for profiles based on past dates. However, you can achieve this goal with a workaround:

Solution: Use a Segment and Manual Flow Trigger

1. Create a Segment for Profiles to Back-Populate

   • Go to Lists & Segments and create a new segment with the following conditions:
     • Properties about someone > First Purchase Date > is before > [today's date].
     • Optionally, add filters to exclude profiles already in the flow to avoid duplicates.

2. Export the Segment

   • Export the segment as a CSV file by clicking Manage Segment > Export Segment to CSV.

3. Manually Trigger the Flow for the Segment

   • Duplicate your existing First Purchase Anniversary Flow and make it a manually triggered flow:
     • Change the trigger from Date Property to List-Based Trigger.
     • Upload the exported CSV file as a new list and set the flow to trigger for this list.
   • Activate the duplicated flow temporarily to process these profiles.

4. Deactivate the Temporary Flow

   • Once all 91K profiles have gone through the flow, deactivate it to avoid conflicts with the original flow.

5. Continue with the Original Flow

   • Keep your original First Purchase Anniversary Flow active for new profiles that meet the date condition moving forward.

Key Notes

• If the flow sends time-sensitive emails (e.g., exactly on the anniversary date), use Delays in the temporary flow to adjust the timing for each email stage.
• Monitor the temporary flow closely to ensure profiles are processed as expected.
• For large datasets, stagger the upload to prevent exceeding Klaviyo’s processing limits.
