How Klaviyo and Mailchimp records line up
Klaviyo and Mailchimp both store the customer's email address. askotter lowercases and trims it on both sides before matching, so the same person shows up as one customer across the two tools.
Klaviyo and Mailchimp both keep the UTM source, medium and campaign values from the visit, so activity lines up campaign by campaign even when no single person can be matched.
Shared between the two: the customer email address and the UTM campaign tags.
What combined reporting uses from each
Combined reporting needs a shared identifier or a shared time grain.
From Klaviyo that means profile emails and phone numbers. From Mailchimp it means subscriber emails.

What each tool sees on its ownShow less
Klaviyo on its own
Klaviyo sees who received, opened and clicked. It credits revenue by its own attribution window and cannot see sales that happen off the store it is connected to.
Timing. Klaviyo logs sends, opens and clicks as events. Apple Mail Privacy Protection preloads images, so open counts run high and clicks are the steadier signal.
Access. A Klaviyo private API key with read-only scopes.
Mailchimp on its own
Mailchimp sees who received and clicked. It cannot see what the reader did after landing on the site.
Timing. Mailchimp reports opens and clicks per campaign. Apple Mail Privacy Protection inflates opens, so clicks are the steadier signal.
Access. The Mailchimp Marketing API with an OAuth connection.
