Klaviyo's page lists more than 30 components (Email Sending, Text Message Sending, Flows, Campaigns, Sign-up Forms, the Shopify integration and others), so a subscription there tells you which part is affected. StatusBird tracks the overall indicator plus the email, SMS, API and forms components.

What usually breaks for Shopify stores when Klaviyo is down?

• Abandoned cart, welcome and post-purchase flows stop sending, and the revenue those flows normally produce quietly disappears
• Scheduled campaigns send late, in the wrong order, or not at all
• Sign-up forms and pop-ups fail to load on the storefront, so list growth stalls
• The Shopify integration stops syncing orders and profiles, which breaks segments and triggers when it catches up
• SMS replies and transactional messages queue up and arrive in a burst after recovery
