Email delivery

Emails are sent from a no-reply address. Customers cannot reply to subscription notification emails. Provide a support contact in your email templates if customers need help.

​
Klaviyo integration

If you use Klaviyo for marketing automation, Appfox Subscriptions can emit subscription events directly to your Klaviyo account. Configure your Klaviyo public API key in the integration settings to enable event tracking.

​
Available Klaviyo events

The following events are sent to Klaviyo when they occur: Each event includes customer information (email, name), subscription details (contract ID, order name, amount, currency), and event-specific data like failure reasons or next billing dates.
Use Klaviyo events to build targeted campaigns. For example, send a win-back flow to customers whose subscriptions were cancelled, or offer loyalty rewards to customers with successful long-term subscriptions.
Test your email templates before going live. Send test emails to yourself and check that variables populate correctly.
