Invoice Email Extension for Magento 2

With this extension, you can add an invoice email address field in the Magento checkout page which facilitates your customers to add an alternate email for receiving the invoice. This allows you to send an invoice to the customer's preferred email address as soon as they place an order.

This extension allows your customers to edit, remove, or replace the additional email address they have specifically provided for receiving invoices. In case they change their email address or prefer to receive invoices on a different email, they can change their provided invoice email from their 'My Account' section.
