100% Preventing Duplicate Emails with Klaviyo Recover

If you've already followed the Manually duplicating flows for Klaviyo Recover guide, your Venon flows include a filter that checks: "Received Email from [Original Flow] zero times since starting this flow."

This works in most cases, but if your flows use re-entry (e.g., every 14 days), there's a small adjustment needed to make sure no duplicate emails are sent.

In Step 4 of the duplication guide, you added this filter to each Venon flow:

Change "since starting this flow" to "in the last [X] days", where X matches the re-entry period of the original flow.

For example, if the original flow has a 14-day re-entry window, change it to: zero times in the last 14 days.

Your original Klaviyo flows don't know about Venon flows. If the Venon flow sends first (because it only has a 10-minute delay), the original flow may still send its own email later — causing a duplicate.

To prevent this, add filters to each original flow that check whether a higher-level Venon flow has already sent an email. This way, if Venon already caught the person further down the funnel, the original flow won't send a redundant email.

Add these filters to your original flows:

No additional filters needed.

This should already be done, just double check that it's the case, because you probably already use those filters in your original flows.

Check that each Venon flow has those filters:

Add these on the trigger, in addition to the existing Venon event filters:

No additional cross-layer exclusions needed.
