Hi @ModernHerbCo,
Klaviyo tracks any conversion made within the attribution window that you set for your account - not just conversions within the first few hours after the email sent. By default, your attribution window is set to 5 days for email clicks and opens. That means that anybody who interacts with your email within 5 days of you sending it, and then purchases, will count as a conversion. You’ll then see this in the conversions tab of the campaign, and in the numbers on the right side of the main Campaigns page.
If you’re only seeing conversions from within a few hours of sending the email, you might have your attribution window set only to a few hours. Visit klaviyo.com/settings/attribution to check on your attribution window. If it’s only a few hours, you can change the time frame, then save. Let me know if you have additional questions about this process, or if I can help with anything else!
