Hi ​@rdraves - thank for your question, here is what is happening:

The email delivery count and the conditional split results often don’t match because:

1. Timing matters: Klaviyo evaluates a contact at the exact moment they hit the conditional split, not when they receive the first email.

2. People drop out of flows: Contacts can exit a flow before reaching the split (i.e. if they unsubscribe, get suppressed, or fail a filter update).

3. Real-time behavior changes: Between receiving the first email and hitting the split, a customer might complete a purchase, start checkout, or no longer meet the filters, so they shift categories.

Example from your screenshot:

• 21 emails delivered

• But conditional split shows only 18 total (3 yes + 15 no)

That means 3 people likely exited the flow or skipped the split step due to:

• Flow filters being re-evaluated mid-flow

• Email address becoming suppressed, bounced, or unsubscribed

• Customer behavior changing (i.e. they start checkout or purchase after receiving the first email)

Here is what I’d check:

1. Check exit conditions

   • Go to the Flow → View Activity Feed → See if those 3 profiles show:

     • Flow exited

     • Suppressed

     • Failed filter due to updated profile data

2. Add a “Flow Filter Snapshot” tag

   • Add a “Profile Property” or event capture at the first email to snapshot their status (i.e. cart value, checkout started, etc.) for comparison at later splits.

3. Delay the conditional split slightly

   • Adding a 1–2 hour delay before the split helps ensure that flow filters and conditional logic aren’t being evaluated simultaneously as real-time behavior shifts.
