What are mail components?

Question

1C-Bitrix

I saw the new components of the store "Component_name for mail" example
What are these components for and what kind of mail do they need? Maybe for the mail of Russia or for Yandex?

Answer 1

It's much simpler: this component displays a list of items in the specified user's shopping cart with "Change Quantity" and "Checkout" links.
This component should be used in conjunction with the "E-mail marketing" module, for example, to remind the user about the "abandoned" cart.
