Magento 2.3 - Customer Firstname in Email

Question

How can we load the customer first name in transactional emails in Magento 2.3?

We tried this, but that does not work;

{{trans "%name," name=$order.getBillingAddress().getFirstName()}}

Answer 1

As mentioned in comments you can use getCustomerFirstname().

{{trans "Hi %first_name," first_name=$order.getCustomerFirstname()}}
