Hi @magnify,
Thank you for sharing your question with the Klaviyo Community.
Keep in mind, when you back-populate a metric-triggered flow, recipients will move through the flow relative to when they performed the triggering action. Also, the flow will only “look back” as far as the time delay you have in the flow. For example, if you are using a 60-day time delay in your flow, back-populating will only capture folks who placed an order in the last 60 days.
The solution here is to extend the time delay to “look back” even further. For example, in your case, since you want to capture folks from as far back as 12/01/2020, you’ll have to replace the time-delay to accommodate that timeframe (60 > 155 days) and back-populate to include your target audience in the flow. As an example, those who placed an order 100 days ago will receive the flow email in 55 days, those who placed an order 30 days ago will receive the flow email in 125 days, and so on.
Lastly, keep in mind that after you update the time delay, the new 155 time delay will apply to new folks entering the flow. Therefore, your best bet after updating to 155 days and back-populating, is to promptly change the time delay back to 60 days so that the 60 day delay applies to new folks entering the flow rather than the 155 day delay. For more use-cases and details on this topic, specifically if you get into more complex use-cases and wish to back-populate, I recommend reading our article on backpopulation.
Thanks and have a great day.
