How to cancel Causebox by mail
Get your account details together
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Causebox names the right account the first time.
Prepare the letter
The letter asks Causebox to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Causebox”. Postbye fills it in from our English template.
Post the letter
Address the envelope to Causebox, Los Angeles, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Hold on to the receipt
File the receipt with the letter. A Causebox charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Causebox cancellation letter goes
Causebox lists 12820 Panama St, Los Angeles, CA 90066 as its mailing address.
Los Angeles, California 90066 is a United States address, so ordinary certified mail reaches it.
The letter greets the reader with “To Whom It May Concern,”; your own details sit under the labels Name, Address and E-mail.

Before you cancel Causebox, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
