What we need for each person
First name, last name, street, city, postcode, and country. Add extra fields if the letter needs them, such as a company or a nickname. Add people on the card page, or upload a spreadsheet if you already have one.

A spreadsheet is optional. Excel (.xlsx) and CSV both work. Extra columns become extra fields in the letter, written as {{Field name}}, the same tokens as the shop.
