Features
- Works with Joomla's built-in contact form, no extra form builder needed.
- Loads your Klaviyo lists and custom fields and maps Joomla contact fields to them.
- Consent is your choice: add every submission, or only the ones where a checkbox of your contact form is ticked.
- Subscriber status, double opt-in and existing-subscriber handling are set per site.
- The visitor never waits: Joomla answers first, then the subscriber is sent to Klaviyo. Failures are logged, never shown to visitors.
- Updates through the Joomla Update System. Supports Joomla 4.4, 5 and 6.

Get started
Install the package, open Components, Contact Form Integration for Klaviyo, paste your API key, select a list, map the fields, decide whether a consent checkbox is required, and save.
