Letter of Goodwill - Certified Mail? (Solved) I have several letters of goodwill I plan to send to see if I can excuse late payments. Should I send these by certified mail?

Usually no, it sends the wrong message. consumers.creditnet.com/Discussions/credit-talk/t-goodwill-letter-certified-mail-46797.html It won't let me post links until I have enough posts.
