Shopify merchants: would you trust a diagnosis based on 3 anonymized screenshots?

I'm trying to understand how much data is actually needed to diagnose a repeat-purchase / win-back problem in a Shopify + Klaviyo store.

Suppose a store has plenty of one-time buyers but isn't sure which customers were realistically recoverable.

Instead of asking for store access, imagine reviewing only:

1. an anonymized flow trigger + filters screenshot
2. an anonymized customer event/activity timeline
3. relevant flow or cohort analytics

No customer names.
No email addresses.
No Shopify/Klaviyo login.
No production access.

For merchants or in-house retention/CRM operators:

Would you be comfortable sharing something like this with an outside analyst if you had a real retention problem?

If not, what would stop you — privacy, trust, effort, or simply not enough value?

I'm specifically interested in merchant/operator perspectives.
