How to cancel Adventure Challenge by mail
Collect the details you need
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Adventure Challenge holds, so the request can be matched to your account.
Prepare the letter
The letter asks Adventure Challenge to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Adventure Challenge”. Postbye fills it in from our English template.
Mail the letter with a receipt
Use certified mail for the 96001 Redding address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
Keep the tracking record with your copy of the letter. If Adventure Challenge bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Adventure Challenge, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
