## How we ranked them

Certified mail matters because it leaves a record you can show: the mailing date, tracking and, with a return receipt, who signed for the letter. Postbye ranks first because it also writes the letter and finds the address; the three do-it-yourself mailers are ranked by the price of a one-page certified letter.
