Do it yourself
Cancel Smithsonian Magazine yourself
TLDR: Open the customer-service menu and use Cancel your Subscription, or call 1-800-766-2149. It takes a few days to take effect, bills that arrive in those days can be ignored, and the help page does not print a refund for time left.
Use Cancel your Subscription
Smithsonian bills the magazine.
- 01Open the Smithsonian magazine customer-service menu.
- 02Use the Cancel your Subscription button.
Some plans renew on their own and do not send a renewal notice. You can still cancel at any time. It takes a few days to take effect. Ignore bills that arrive in those days. You can also call 1-800-766-2149, Monday through Friday 7:00 a.m. to 7:00 p.m., and Saturday 8:00 a.m. to 5:00 p.m. If Synapse sold the subscription, cancel with Synapse at (877) 755-8550, 9:00 a.m. to 10:00 p.m. Eastern, or at magcustomerservice.com under My Subscriptions. Apple, Barnes & Noble Nook, and Zinio copies are cancelled with that store. Those copies do not include the membership benefits or the full archive. To pause delivery, call. The page does not say the online button does that.
Mail a notice
You want it on paper.
- 01Write that you are cancelling, and include the name on the subscription.
- 02Mail it to Smithsonian Magazine, P.O. Box 8504, Big Sandy, TX 75755.
The help page lists that box for customer service and for payments. Cancel online or by phone as well. A letter can arrive after the next bill is already on the way.
