How Klaviyo Measures Attribution

By default, Klaviyo uses a ‘last click’ attribution model for email and SMS. In essence, this means that the last message that the user clicked on before becoming a conversion will receive credit for the conversion itself. Though this needs to be done within the attribution window. Let us take a quick look at how it works:

• For Email: The default attribution window is five days. Therefore, if a customer clicks on an email and makes a purchase within that window, then they would get an email with credit.
• For SMS: The attribution window is typically 24 hours.
• Multi-Channel: If a customer receives multiple messages across different channels, like an email and an SMS), Klaviyo will credit the last interaction that led to the conversion.

Users are able to adjust these attribution windows in their Klaviyo settings. This though, depends on their customers’ behavior, whether it aligns with your marketing strategy or not.
