Enhanced Guest Customer (not logged-in) Interaction Events

1) Cart Created Event for Not Logged-In Customers

Currently, when a non-logged-in customer enters their email during checkout, they do not receive a shopping cart abandonment email. To enhance user experience and encourage completion of purchases, I propose implementing a cart_created event that triggers an email for these users as well. By doing so, we can proactively engage with potential customers who haven’t logged in, nudging them towards completing their purchase.

2) Order Completed Event for Guest Orders

Unlike the original Brevo module, the current implementation does not generate an order_completed event for orders from guests (not logged-in). Having this event is essential for post-purchase follow-up, including order confirmation and feedback requests. Implementing this feature would improve communication with guest customers and enhance overall satisfaction.
