How to cancel Endurance by mail
Get your account details together

Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Endurance”: close the Endurance account, stop every charge and reply in writing.
Mail the letter with a receipt
Post it by certified mail to Endurance in Northbrook, United States, using the exact address below, and note the tracking number.
File the delivery record
Delivery confirmation is your evidence that Endurance was asked. Watch the next statement or two for any further Endurance charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Every address we hold for Endurance, with the envelope wording
Before you cancel Endurance, check these
- 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.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
