Write the cancellation request
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – America's Test Kitchen / Cook's Illustrated”: close the America's Test Kitchen / Cook's Illustrated account, stop every charge and reply in writing.
Send it by certified mail

Cancelling a news or magazine subscription

Publishers often move you from an introductory price to the standard rate and can steer cancellations towards phone or chat, so a written request is the record that you asked.

A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.

America's Test Kitchen / Cook's Illustrated lets you cancel directly (online (My Account > Edit Membership > Cancel Membership); magazine by account page or phone). A letter is the fallback that leaves a dated record when the direct route fails.
