Hi @toad78, If you’re looking to collect phone numbers from the cart and sync them to your Mailchimp audience, you can extend the Mailchimp for WooCommerce plugin using custom merge tags. A guide on how to add custom merge tags can be found here: Custom Merge Tags – Mailchimp for WooCommerce Integration.
Incorporating this functionality requires modifications to your functions.php
file or a custom plugin, which can be complex. If you’re not comfortable with code changes, it might be best to engage a third-party developer with experience in WordPress and WooCommerce customizations. This ensures that changes are made correctly and your site remains stable and secure.
