When making a birthday gift to my sponsored child, Samuel, the telephone rep said I need to send a letter to my sponsored child or the pop up card I’m sending would not be delivered. Does the card with a signature not count as a letter? Will the card not be mailed unless I put a seperate paper letter in with it? I didn’t want to send another letter because I feel I’m writing too much as it is, but I wanted to send the fun card just to bring a smile to his face. Please let me know so I can either write a letter and mail it or just mail it. Thank you.
