import_address_list
Import address list
Use this when the user wants to mail printed cards to people at US postal addresses and gives the addresses as pasted text, a CSV, or an .xlsx spreadsheet. Reads names and addresses, checks required fields and US address format, and saves them as a recipient list. USPS verification runs only when it is configured; usps_checked in the result says whether it ran. Format checks alone do not confirm that an address is deliverable. Returns a list_id, how many rows are ready, and the problem for each row that needs fixing. Up to 300 recipients; pass list_id to append rows to an existing list. US addresses only. Not for e-cards or email, addresses outside the US, or advertising mail to purchased or rented lists.
